22kW Skid Mounted Low Pressure VSD Single Stage Air Compressor

Elily 22kW Skid-Mounted Low-Pressure VSD Single Stage Rotary Screw Air Compressor supports customizable working pressure of 3–6 bar. Featuring plug-and-play skid-mounted construction, it delivers high airflow with outstanding energy efficiency for low-pressure production demands.

1. Dedicated PM VSD Low-Pressure Design, Superior Energy Saving

Fitted with a 22kW permanent magnet variable frequency motor, the optimized single-stage low-pressure airend adopts upgraded rotor profiles. Working pressure is adjustable within 0.3–0.6 MPa, with maximum airflow up to 6.5 m³/min at 0.3 MPa. Practical field tests prove 25%–35% energy savings versus conventional fixed-speed compressors, ideal for low-pressure continuous operation.

2. Integrated Skid-Mounted Structure, No Foundation Required

The whole machine is assembled on a heavy-duty steel skid base. No anchor bolt installation is needed. After positioning via forklift or crane, only power and pipe connection are required. Fully pre-commissioned before shipment, the unit cuts on-site installation time by 70% for rapid commissioning.

3. Single-Stage Low-Pressure Compression for Optimized Efficiency

Single-stage compression avoids inter-stage pressure loss, performing more efficiently at low pressure than two-stage compression systems. It runs with lower discharge temperature, extends lubricant service life and reduces routine maintenance expenses. For aeration processes, this 22kW low-pressure model achieves 12% better specific power performance than mainstream industry benchmarks.

4. Comprehensive Safeguards for Severe Working Conditions

The permanent magnet motor is IP54 protected with Class F insulation. The control cabinet comes with built-in dust filters, adapting to dusty, high-temperature workshops such as cement production plants.

Multiple safety protections cover over-temperature, over-pressure, over-current, phase loss, phase reversal and unstable voltage, enabling reliable 24-hour continuous unattended operation.
