In industries that rely on efficient gas transfer and vapor recovery—like oil & gas, chemicals, refrigeration, and liquefied gas handling—the choice of a compressor is not just about flow rate. It's about long-term reliability, efficiency, environmental compliance, and uptime. Blackmer’s reciprocating gas compressors deliver all of that—and more.
This guide offers a deep dive into the features, functionality, and practical advantages of Blackmer’s LB, HD, and NG Series reciprocating compressors. Whether you're designing a new gas system or upgrading aging equipment, understanding these compressor lines is key to making a smart, cost-effective investment.
What is a Reciprocating Gas Compressor?
A reciprocating gas compressor is a type of positive displacement machine. Using pistons that move within a cylinder, these compressors draw in gas, compress it, and then discharge it at a higher pressure. The up-and-down motion of the piston produces a pulsed flow of gas and is highly effective for high-pressure applications.
Unlike rotary or centrifugal compressors, reciprocating units excel in applications that demand:
Variable flow and pressure
Tight sealing against gas leaks
Handling of vapor, gas, or mixed-phase streams
Overview of Blackmer’s Reciprocating Compressor Series
LB Series – For Liquefied Gases like LPG & Anhydrous Ammonia
Blackmer’s LB Series is purpose-built for handling liquefied gases. These compressors are widely used in propane terminals, bulk storage facilities, cylinder filling stations, and railcar unloading operations.
Core Features:
High-efficiency valves for smooth flow
Self-adjusting piston rod seals for reduced leakage
Ductile iron pistons for maximum durability
Available in multiple bore/stroke sizes to match flow and pressure needs
These compressors are the gold standard for liquefied petroleum gas (LPG) systems and vapor recovery applications.

HD Series – For Industrial Gas Compression
For heavier gases and more rugged environments, Blackmer’s HD Series offers unmatched toughness. These compressors are suitable for industrial gases such as:
Carbon dioxide (CO₂)
Nitrogen
Refrigerants
Air and specialty gases
Standout Benefits:
Single and two-stage designs for higher compression ratios
Air- or water-cooled configurations
Oil-free options available
Superior reliability in process gas applications
Whether you're bottling gases, maintaining system pressure, or recovering vapors from storage, the HD Series delivers industrial-grade results.
Industrial Air Services can help you size and install the right HD Series compressor. Call (615) 641-3100 to speak with a specialist.
NG Series – For Natural Gas and Wellhead Applications
The NG Series is Blackmer’s answer to oilfield and natural gas compression. Designed specifically for clean and sour gas applications, it’s the go-to for upstream energy producers.
Why it Stands Out:
Oil-free operation prevents contamination
Designed for low maintenance and high run-time
Compatible with sour gas environments (H₂S)
Equipped with a full compartment distance piece for environmental safety
Applications include wellhead compression, tank vapor recovery, and gas gathering. The NG Series is also ideal for operations looking to reduce methane emissions and comply with environmental regulations.

Advantages of Blackmer Reciprocating Compressors
Whether you're comparing to rotary vane, diaphragm, or screw compressors, Blackmer’s reciprocating designs offer unique advantages:
Exceptional Gas Tightness: Perfect for volatile or hazardous gases
Versatility: Handles a wide range of gases and operating conditions
Ease of Maintenance: Designed for quick serviceability
Durability: Materials like ductile iron and stainless steel extend service life
Energy Efficiency: Engineered to reduce power consumption at rated loads
When paired with Industrial Air Services’ local support for sales, installation, and parts, you get not just a pump—but a fully backed system solution.
Selecting the Right Compressor for Your Operation
To ensure you’re choosing the best system, consider the following factors:
Type of gas being compressed
Target suction and discharge pressure
Volume of gas (CFM or SCFM)
Ambient and process temperatures
Environmental regulations
Required certifications (e.g., API, ASME, NFPA)
Industrial Air Services offers free consultations and system audits to determine the right size and model for your needs. With offices in Nashville, Knoxville, and Chattanooga, we’re ready to support your project from start to finish.
Real-World Example: Vapor Recovery at a Tennessee Propane Terminal
A regional propane storage facility in Tennessee was losing thousands of dollars each month in unrecovered vapor during loading and offloading. The facility installed a Blackmer LB942B reciprocating compressor as part of a dedicated VRU (vapor recovery unit).
Results included:
A 38% reduction in gas loss from flaring
Fast ROI: The compressor paid for itself in less than 9 months
Maintenance downtime reduced to once a year
