SH-AH PM VSD Single-Stage Screw Compressor
The workhorse for general plant air. A permanent-magnet synchronous motor with inverter control follows actual demand, while the centrifugal fan holds stable cooling across 30–280 kW.
SH-AH PM VSD Single-Stage Screw Compressor
The workhorse for general plant air. A permanent-magnet synchronous motor with inverter control follows actual demand, while the centrifugal fan holds stable cooling across 30–280 kW.
Overview
SH-AH couples a PM synchronous motor directly to the airend, removing belt and coupling losses; efficiency at low speed falls away far less than with asynchronous VSD designs. Single-stage compression keeps the structure simple with fewer service points, and the centrifugal fan maintains stable discharge temperature in warmer rooms. The controller regulates speed against line pressure, cutting unloaded running time in workshops with fluctuating demand.
Key features
PM motor coupled directly to the airend — no belt slip or coupling loss, better part-speed efficiency.
Closed-loop pressure control matches output to consumption, reducing load/unload and throttling losses.
High static pressure and good dust tolerance suit less-clean workshop environments.
Inverter soft starting limits inrush current and is gentler on the plant network.
