Compressors

The Air Horse EPM-150A is a large-capacity, variable-speed direct-drive screw air compressor from the EPM series, designed to deliver high-volume compressed air with exceptional energy efficiency for heavy industrial applications. Powered by a 110 kW (150 HP) permanent magnet synchronous motor, it achieves a free air delivery of 20.5 m³/min (724 CFM) at 8 bar working pressure, with a 10 bar variant also available delivering 17.9 m³/min (632 CFM).,The integrated variable frequency drive (VFD) continuously adjusts motor speed to match real-time air demand, eliminating wasteful load/unload cycling and delivering dynamic energy savings of up to 35% compared to fixed-speed alternatives. The direct-drive configuration with a permanent magnet motor eliminates gearbox, belt, and coupling losses, achieving near-100% mechanical transmission efficiency. The system features millisecond-level response for speed correction within 3 ms, maintaining stable discharge pressure control within a minimal range and enabling soft-start operation that extends motor and bearing life.,The compressor is housed in a soundproofed enclosure with an intelligent controller and is engineered for continuous duty in demanding environments including large-scale manufacturing, PET blowing, laser cutting, and heavy engineering plants. Its compact footprint and straightforward installation (requiring only main power connection) make it a practical high-capacity solution for industrial compressed-air systems.
