Axtel GM-7L Rotary Piston Blower

Applications & Use Cases

• Pneumatic conveying of dry bulk materials in food processing lines.
• Aeration in wastewater treatment or fermentation processes.
• Vacuum applications for packaging or material handling.
• Agitation of liquids in mixing tanks.
• Drying processes requiring forced air circulation.

Typical Specifications

Typical capacity

For this class of equipment, rotary piston blowers commonly offer airflows ranging from 100 to 500 m³/hr, depending on the specific model and application.

Power supply

Units of this type typically operate on a 3-phase industrial power supply, commonly 400V, 50Hz in the UK.

Motor power

Motor sizes for rotary piston blowers like the GM-7L typically range from 2.2 kW to 11 kW, influencing the blower's output and pressure capabilities.

Operating pressure

Rotary piston blowers are generally designed for low-pressure applications, typically providing pressures up to 1 bar (gauge) or vacuum levels up to -0.5 bar (gauge).

Footprint

The footprint for a unit of this type is typically compact, often around 0.5m x 0.5m x 0.8m, though this can vary with ancillary equipment.

Noise level

While specific levels vary, rotary piston blowers commonly operate in the 75-85 dB(A) range, often requiring acoustic enclosures in sensitive environments.

Frequently Asked Questions

• What is the primary difference between a rotary piston blower and a rotary lobe blower?

  Rotary piston blowers typically offer higher volumetric efficiency and can achieve slightly higher pressures or deeper vacuum compared to standard rotary lobe blowers, often with less pulsation.

• Is this type of blower suitable for continuous operation?

• What maintenance is typically required for a rotary piston blower?

• Can this blower handle moist air or vapours?

• What are the typical installation requirements for a unit like this?
