Working Principle
It features an eccentric rotor with sliding vanes inside a cylindrical casing.
As the rotor spins, the vanes extend/retract, forming variable-volume chambers.
Air is trapped in these chambers at the inlet, then compressed and discharged at the outlet.
This continuous rotation ensures smooth, steady airflow with minimal pulsation.
Key Features
Compact & Lightweight: Small footprint for easy installation in tight spaces.
Low Noise & Vibration: Quieter than Roots blowers, ideal for noise-sensitive areas.
Stable Airflow: Positive displacement design delivers constant flow despite pressure fluctuations.
Simple Structure: Few moving parts (rotor, vanes, casing) for easy maintenance and high reliability.
Oil-Lubricated or Dry: Oil-lubricated models offer better sealing; dry types prevent oil contamination.
Typical Specifications
Airflow: Up to 10 m³/min.
Pressure: Up to 50 kPa (0.5 bar).
Drive: Direct-coupled or belt-driven motor.
Main Applications
Wastewater Treatment: Aeration for small sewage plants, ponds, and septic systems.
Aquaculture: Oxygenation for fish ponds and aquariums.
Pneumatic Conveying: Light-duty transport of powders and granules.
Industrial Processes: Dust removal, gas supply, and low-pressure ventilation.
