Why Compressed Air Treatment Matters

Compressed air, if untreated, is a liability rather than an asset. It contains:

• Water vapor that condenses into damaging moisture

• Oil aerosols that contaminate downstream equipment

• Solid particulates from dust and wear

• Microorganisms that can thrive in warm, moist environments

Left unaddressed, these contaminants can:

• Shorten equipment life

• Cause corrosion in pneumatic tools and pipelines

• Ruin product batches (especially in food, beverage, and pharmaceutical sectors)

• Lead to regulatory compliance issues

• Increase unplanned downtime and maintenance costs

That’s why air treatment systems are an essential part of any reliable compressed air network—and why Powerex’s TDD Air Treatment Skid is such a valuable addition.

Sustainable Solutions: Bauer Compressors’ Innovations in Renewable Natural Gas (RNG) and Biogas Compression

As the world shifts toward sustainable energy sources, one resource continues to gain momentum for its efficiency, renewability, and environmental benefits: Renewable Natural Gas (RNG). Derived from organic waste, RNG—also known as biomethane—is a clean-burning alternative to traditional fossil fuels, and it’s increasingly used in transportation, power generation, and heating.

But transforming raw biogas into usable RNG isn’t simple. It requires a complex system of collection, purification, and—critically—compression. That’s where Bauer Compressors shines.

With more than 75 years of engineering experience and a growing footprint in the clean energy sector, Bauer has developed purpose-built systems to help operators capture, clean, compress, and deliver RNG safely and efficiently. From landfills to farms to wastewater treatment facilities, Bauer's advanced compression technology is helping drive the future of green energy.

📞 To speak with an RNG compression specialist, call (615) 641-3100 today.

What Is Renewable Natural Gas?

RNG is chemically identical to fossil natural gas but comes from organic sources such as:

• Agricultural waste (manure, crop residues)

• Landfill gas (decomposing municipal solid waste)

• Wastewater treatment plants

• Food processing byproducts

These materials naturally produce methane (CH₄) during decomposition. That methane is captured as biogas, then processed to remove:

• Moisture

• Carbon dioxide (CO₂)

• Hydrogen sulfide (H₂S)

• Volatile organic compounds (VOCs)

Once purified to pipeline-grade quality (typically >96% methane), the resulting gas is considered RNG and can be:

• Injected into the natural gas grid

• Compressed into CNG for vehicle fueling

• Used for onsite power or heating

Why Compression Is Essential in RNG Production

Before RNG can be stored, transported, or injected into the pipeline, it must be compressed to meet volume and pressure requirements. This process includes:

• Post-purification compression for pipeline injection (200–1,200 psi)

• Storage compression into high-pressure vessels

• Dispensing compression for CNG fueling stations (up to 3,600 psi)

Without robust and reliable compression, RNG cannot be distributed or monetized effectively. Bauer’s systems are built specifically for this stage—handling challenging gas streams with high uptime and efficiency.

The Rise of Hydrogen and Natural Gas

Hydrogen: The Fuel of the Future

Hydrogen is a clean energy carrier that produces only water when burned or used in fuel cells. Its applications include:

• Fuel for hydrogen-powered vehicles (FCEVs)

• Industrial heating and processes

• Grid energy storage

• Backup power systems

However, hydrogen must be compressed to high pressures—often 350 bar (5,000 psi) or 700 bar (10,000 psi)—to be stored and distributed efficiently.

Natural Gas and RNG

Compressed Natural Gas (CNG) is already widely used in fleets, transit, and utility vehicles as a cleaner-burning alternative to diesel or gasoline. Renewable Natural Gas (RNG), derived from organic waste sources like landfills or agriculture, further reduces emissions and supports circular economies.

To be usable as a fuel, both CNG and RNG must be:

• Cleaned (scrubbed of impurities)

• Compressed to high pressure

• Safely stored and dispensed

This is where Bauer Compressors plays a pivotal role.

Why Compression Matters

Gases like hydrogen and methane are low-density by nature. To make them practical for storage and transport, they must be compressed:

• To reduce volume

• To match fueling or process pressures

• To improve energy efficiency

• To meet regulatory and safety requirements

Compressors must operate reliably, handle extreme pressures, and meet industry-specific codes such as NFPA, ASME, and CSA.

Advancements in Gas Injection Technology: How Bauer Compressors Revolutionized Plastics Manufacturing

The plastics industry has seen massive advancements over the last few decades—faster production, lighter materials, and greater design flexibility. One of the most significant innovations fueling that progress is Gas Injection Molding (GIM), a process that allows manufacturers to produce complex plastic parts with less material, lower cycle times, and superior strength-to-weight ratios.

At the heart of this revolutionary method lies high-pressure gas compression, and no company has done more to advance and refine this technology than Bauer Compressors. With their robust engineering, oil-free systems, and industry-specific customization, Bauer compressors have become the gold standard in gas injection systems around the world.

In this post, we’ll explore how gas injection molding works, why compressed gas is essential to its success, and how Bauer Compressors—supported by Industrial Air Services in Nashville, Knoxville, and Chattanooga—is helping plastics manufacturers raise the bar in performance, quality, and efficiency.

📞 Call (615) 641-3100 for expert help with gas-assist system design, installation, and support.

What Is Gas Injection Molding?

Gas Injection Molding is a plastics manufacturing process that uses pressurized gas (typically nitrogen) to hollow out sections of molten plastic inside a mold. The result is a part with:

• Hollow channels instead of solid plastic cores

• Reduced material usage

• Better dimensional stability

• Minimal surface defects

• Lighter overall weight

GIM is ideal for parts that need to be strong but not overly heavy—such as:

• Automotive interior and exterior parts

• Appliance housings

• Furniture components

• Medical device enclosures

• Electronics cases

The process requires a high-pressure gas source—reliable, clean, and precisely controlled—to displace the plastic within milliseconds and form the desired structure.

Why High-Pressure Gas Matters

The success of a gas injection molding system hinges on pressure accuracy and timing. Nitrogen must be injected:

• At precisely the right point in the injection cycle

• At high enough pressure to fully displace the molten plastic

• In a clean, oil-free form to avoid contamination or mold fouling

This is why the compressor system is the most critical component of any GIM installation. Inconsistent pressure or contaminated gas can ruin molds, damage equipment, and lead to massive scrap rates.

The Importance of Pure Air in Industrial Applications: Why Air Quality Matters More Than You Think

When people think of “clean air,” they often picture medical facilities or laboratories. But in reality, pure air is just as critical in industrial environments—even when the air isn’t being inhaled by people. In manufacturing, food and beverage production, electronics assembly, and countless other sectors, the quality of compressed air directly impacts product safety, equipment performance, and operational efficiency.

Using the wrong type of air—or failing to treat it properly—can lead to contamination, machine failure, spoiled products, and regulatory violations. In this blog, we’ll dive into why air purity is essential in industrial settings and how Powerex compressors, supported by Industrial Air Services, help businesses across Nashville, Knoxville, and Chattanoogamaintain clean, compliant, and efficient operations.

📞 Have questions about your facility’s air quality? Call (615) 641-3100 to speak with an expert.

What Is “Pure Air” in an Industrial Context?

“Pure air” typically refers to air that is free of oil, particulates, water vapor, and other contaminants that could interfere with a process, product, or machine. Depending on the industry and application, the required level of purity can vary.

The ISO 8573-1 Air Quality Standard

To standardize what “clean” means, the ISO 8573-1 classification system ranks air quality in terms of:

• Solid particles

• Water vapor (humidity or condensate)

• Oil content (aerosol and vapor)

For example:

• ISO Class 1 is extremely pure (often used in electronics and medical applications)

• ISO Class 4 or 5 may be acceptable for general industrial use

Powerex compressors, particularly oil-less models, can be paired with dryers and filters to meet ISO Class 0 or Class 1 standards—meaning no detectable contamination.

Key Industries Where Air Purity Matters

1. Food and Beverage Production

Compressed air is often used for:

• Packaging (blow molding, sealing)

• Mixing or moving ingredients

• Clean-in-place (CIP) systems

Contaminated air can spoil products or lead to bacterial growth, prompting costly recalls. Powerex oil-free systems prevent oil or water from entering your production line.

2. Electronics Manufacturing

Tiny contaminants can ruin circuit boards, hard drives, and chips. In this environment, even microscopic oil aerosols are unacceptable.

Clean air is essential for:

• Pick-and-place machines

• Soldering and coating lines

• Static pressure maintenance in cleanrooms

3. Automotive and Aerospace

In these industries, compressed air powers tools that must perform with precision and consistency. Oil mist or moisture can affect:

• Paint finishes

• CNC machining accuracy

• Robotic assembly lines

4. Pharmaceuticals and Cosmetics

Much like in food production, any contamination of the final product—or even the packaging—can result in health risks, regulatory penalties, and lawsuits. FDA, GMP, and ISO compliance all require the use of clean, filtered air.

5. Plastics and Injection Molding

Even a small amount of water vapor or oil can affect the curing process or cause voids and defects in molded products.

Risks of Using Impure Compressed Air

Many industrial facilities underestimate the cost of air impurities. Consider the following risks:

• Product contamination

• Clogged or fouled pneumatic equipment

• Downtime due to tool failure

• Rework or scrap costs

• Non-compliance with OSHA, FDA, or ISO standards

• Customer complaints or brand damage

In some industries, one drop of oil can contaminate thousands of products—or shut down an entire production line.

How Powerex Ensures Clean Air

Powerex offers oil-less scroll, piston, and rotary compressors specifically designed for environments where air purity matters. Their systems are:

• Oil-free by design—no oil in the compression chamber means no risk of contamination

• Equipped with advanced filtration to remove particles, vapors, and condensate

• Available with integrated dryers (desiccant or refrigerated) to control moisture

• Smart monitored—you can track air quality metrics in real time

Air Treatment Matters: More Than Just the Compressor

Even the best compressor can deliver contaminated air without the proper accessories. Powerex systems can be bundled with:

• Particulate filters (remove dust, rust, and other solids)

• Coalescing filters (remove oil aerosols)

• Activated carbon filters (remove odors and vapors)

• Refrigerated or desiccant dryers (remove moisture)

• Pressure and dew point monitors (track performance)

This layered approach ensures your air quality stays within your target ISO class—regardless of environmental conditions.

Real-World Example

Industrial Bakery – Nashville, TN

The facility used compressed air for ingredient transport and packaging. An older lubricated compressor introduced oil vapor into the production area, triggering a failed FDA inspection.

But no matter how advanced or well-built your compressor is, one truth remains: consistent maintenance is the key to performance, efficiency, and longevity.

In this post, we’ll share practical, actionable maintenance tips for keeping your air compressor system in top condition. Whether you’re operating an industrial setup or a critical medical air system, following these guidelines can extend your equipment’s life and prevent costly downtime.

This information is proudly provided by Industrial Air Services, your trusted source for Powerex compressors in Nashville, Knoxville, and Chattanooga. Call (615) 641-3100 for expert service, maintenance plans, and support.

Why Maintenance Matters

Air compressors operate under extreme pressure, temperatures, and in some cases, around the clock. Without proper care, even the most reliable unit can experience:

• Loss of pressure

• Increased energy consumption

• Mechanical wear or pump failure

• Contamination of air or vacuum systems

• Emergency shutdowns

Routine maintenance not only prevents major breakdowns but also keeps your system running at peak efficiency, helping you save on energy and avoid unplanned expenses.

Tip #1: Read the Manufacturer’s Manual (Seriously)

The best maintenance schedule is the one recommended by the manufacturer. Powerex systems, for example, come with detailed manuals that outline:

• Maintenance intervals

• Parts to inspect and replace

• Alarm codes and what they mean

• Cleaning and lubrication instructions (if applicable)

Skipping the manual is like driving a car without knowing how to check the oil. Start there—it’s your roadmap.

Tip #2: Perform Daily Visual Inspections

A quick daily check can help catch early signs of trouble before they become serious. Look for:

• Unusual noise or vibration

• Oil or water leaks

• Dust or debris buildup

• Indicator lights or alarms

• Abnormal smells or heat levels

Train your team to do a walkaround every day, especially in multi-shift operations.

Tip #3: Monitor Air Intake Quality

Your compressor’s intake air should be clean and dry. If your system is pulling in:

• Dust

• Moisture

• Chemical fumes

…it can affect the longevity of the filters, valves, and pump itself. Consider relocating the intake or installing pre-filtersin dusty environments.

Tip #4: Replace Air Filters Regularly

Clogged air filters reduce efficiency and strain your compressor. In most Powerex systems, the air filters are accessible and easy to change.

• Check filters monthly (or more often in dirty environments)

• Replace when clogged or discolored

• Use only OEM filters to ensure proper fit and filtration performance

Pro tip: Keep spares on hand to avoid downtime.

Tip #5: Keep Your System Dry

Moisture is the enemy of clean compressed air. Without proper drainage or drying, water can:

• Corrode internal components

• Introduce microbial growth in medical systems

• Contaminate pneumatic tools or lab processes

Always check:

• Moisture separators

• Drain valves

• Desiccant or refrigerated dryers

Powerex systems often include integrated drying solutions, but they still need regular monitoring and servicing.

Tip #6: Check and Change Lubricant (For Lubricated Units)

While most Powerex compressors are oil-less, if you’re using a lubricated model (such as some rotary screw units), maintaining oil levels and quality is critical.

• Use only the specified oil type

• Change oil on schedule, or if it becomes milky, burnt, or contaminated

• Don’t mix oils—different types can break down sealing and lubrication

For oil-less units, skip this step but still monitor components for mechanical wear or signs of dry friction.

Tip #7: Inspect Belts and Couplings

Belt-driven models require regular belt inspections. Look for:

• Cracks or fraying

• Improper tension

• Misalignment

A worn belt can reduce efficiency and even snap, leading to unexpected downtime.

Powerex scroll compressors, popular in medical and lab environments, use direct-drive systems with fewer moving parts, reducing this maintenance need—but it’s still good to inspect couplings and motor mounts.

Tip #8: Maintain a Clean Work Area

Dust, chemical fumes, and general shop grime can shorten the life of your compressor. Keep the area:

• Free of clutter

• Well ventilated

• Protected from temperature extremes

Don’t place flammable items or chemical containers near the compressor intake.

Tip #9: Monitor Performance Metrics

Many Powerex systems come with digital controllers and sensors to track:

• System pressure

• Run hours

• Load/unload cycles

• Filter status

• Moisture levels

Monitor these regularly and set alerts for out-of-spec readings. Staying ahead of system trends is a great way to schedule maintenance before problems arise.

But what does it actually mean to comply with NFPA 99? Why does it matter? And how do Powerex systems ensure that your facility meets (and exceeds) these requirements?

In this in-depth guide, we’ll explore the history, structure, and purpose of NFPA 99, the consequences of non-compliance, and how Powerex medical air systems, installed and supported by Industrial Air Services, can help your facility stay fully compliant.

What Is NFPA 99?

NFPA 99 is the Health Care Facilities Code, which outlines risk-based performance criteria for healthcare systems—including medical gas and vacuum systems, electrical systems, fire protection, and more. It’s widely recognized and enforced across the U.S. as the gold standard for ensuring patient safety.

Who Needs to Comply?

Any facility where patient care is administered—hospitals, dental offices, outpatient surgical centers, and clinics—must comply with NFPA 99 if they use medical air or vacuum systems. This includes systems that power ventilators, anesthesia equipment, surgical tools, and more.

Why Medical Air Systems Are Regulated

Medical air is considered a life-supporting gas, which means its purity, availability, and pressure must be strictly controlled. Impure or insufficient air can cause major complications during surgery or recovery and could even endanger lives.

NFPA 99 aims to ensure:

• Purity of air delivered to patients

• Redundancy in case of equipment failure

• Alarm systems to alert staff of issues

• Routine maintenance and inspection protocols

• Proper installation practices for safety and hygiene

Key NFPA 99 Requirements for Medical Air Systems

1. Category 1 Systems for Life-Support

NFPA 99 divides systems into categories based on risk. Category 1 systems—like medical air—are used for life support and must meet the most rigorous safety and design standards.

2. Redundancy & Reliability

Medical air compressors must have redundant components. If one compressor fails, a backup must take over without interrupting air supply.

Powerex systems offer duplex, triplex, and even quadplex configurations, ensuring that there's always a redundant pumpavailable.

3. Monitoring & Alarms

NFPA 99 mandates monitoring of key metrics such as:

• Air pressure

• Dew point (moisture level)

• Contaminants

• Pump status

These readings must be constantly available, with alarms located both at the system and in central monitoring stations.

4. Dryers and Filters

The air must be dry and free of contaminants. NFPA 99 specifies requirements for filtration and drying equipment, including the use of desiccant dryers, particulate filters, and carbon filters.

Powerex systems include high-quality filtration and moisture removal technologies designed specifically to meet these needs.

5. Piping and Labeling Standards

The standard also outlines best practices for piping materials, system layout, labeling, and color coding, ensuring safe installation and minimizing human error.

Common Compliance Pitfalls

❌ Inadequate Redundancy

If your system has no backup compressors or tanks, you're out of compliance—and risking patient safety.

❌ Outdated Alarm Systems

Many older systems lack the proper real-time alerts and monitoring required by modern NFPA 99 standards.

❌ Poor Documentation

NFPA 99 requires clear logs of system inspections, maintenance, and performance checks.

❌ Using Non-Medical-Grade Equipment

Only medical-grade, certified systems may be used for life-supporting air applications.
