MD Pneumatics rotary lobe blowers supply air or vacuum for applications such as pneumatic conveying, process gas boosting, and vacuum excavation. Equipment selection depends on the required flow and operating conditions.

Our page features PD Plus, CP, Equalizer RM and DF, and QX blowers, along with packaged systems. Each series has different capabilities, so compare the specific model against your application requirements.

Rotating lobes carry pockets of gas from the inlet toward the discharge. The connected system creates resistance to that flow, so pressure depends on the application and must remain within the blower's limits.

Selected models support pressure or vacuum duties. Confirm the operating direction, allowable pressure differential, speed, and temperature for the proposed service rather than assuming one configuration suits every application.

A package combines the blower with supporting equipment, which may include a motor, drive, base, silencers, enclosure, and controls. Confirm the quoted scope, especially protection devices and installation requirements.

Provide the material type, transfer rate, conveying distance, pipe diameter, elevation changes, and expected pressure losses. The blower must match the conveying system's airflow needs without exceeding its pressure or temperature limits.

Hotter inlet air changes gas density and increases the starting temperature for compression. Selection should account for seasonal conditions, equipment room ventilation, and any heat entering the blower through process piping.

Possibly. Check motor power, speed, electrical supply, drive arrangement, and the full operating load. Matching the old motor's horsepower alone does not confirm that the replacement blower will operate correctly.

Review inlet and discharge silencing, enclosure design, vibration isolation, and piping supports. Noise can travel through both air and connected structures, so the most effective solution addresses the complete installation.

Inlet filtration helps keep abrasive particles out of the blower. A loaded filter also restricts airflow, so filter condition should be monitored and elements serviced according to the equipment manufacturer's instructions.

Follow the model's manual for lubricant checks and changes, drive inspections, filter service, and operating checks. Record temperature and vibration trends so changes can be investigated before they disrupt production.

Possible causes include excessive pressure differential, restricted airflow, poor ventilation, incorrect speed, or lubrication problems. Check the operating readings against the rated limits before deciding whether internal repairs are needed.

Investigate inlet restrictions, leaks, changes in system resistance, drive speed, and wear. Compare measurements under the same operating conditions; readings taken at different pressures or temperatures can be misleading.

Compare the condition of the housing and rotating components, repair cost, parts availability, and current process requirements. A rebuild may suit a sound machine, while changed demand can justify selecting different equipment.

Send the blower nameplate, motor data, operating airflow and pressure, installation photos, and any available drawings. Include the handled gas, operating hours, and problems with the current system.
