15HP 8bar PM Variable Frequency Single Screw Industrial Air Compressor

This 15HP permanent‑magnet variable‑frequency screw air compressor is a single‑unit direct‑drive model built for continuous industrial operation. Equipped with high‑efficiency PM motor, it adjusts air output dynamically according to actual consumption to cut down idle power waste. Air‑cooled structure keeps stable performance under regular workshop conditions. Low running noise and clean outlet air make it well‑suited for small‑to‑medium workshops, machinery processing and general pneumatic equipment support. Compact footprint simplifies installation and on‑site layout.

Product Introduction

Main Advantages

 

Energy‑saving permanent magnet motor The variable‑frequency system matches air supply with real‑time air demand. When air consumption drops, the motor automatically reduces speed instead of running no‑load, bringing obvious electricity savings for users with fluctuating air‑use conditions.

Reliable direct‑drive transmission Direct coupling between motor and air‑end removes belt‑loss trouble. Fewer wearing parts mean less routine maintenance and stable long‑hour continuous running.

Comfortable low‑noise operation Optimized internal silencing structure keeps operating noise at 57±2dB(A). It will not create heavy noise interference inside production workshops.

Stable air‑cooled heat dissipation Air‑cooled design works well in ordinary factory environments, no extra cooling water system required. It lowers the threshold for on‑site deployment.

Clean compressed air Residual oil content of delivered compressed air is controlled within ≤3ppm, which can effectively protect downstream pneumatic components and extend service life of air‑driven tools.

Gentle frequency‑conversion startup Frequency‑conversion starting limits starting current, avoiding sharp impact to factory power grid.

Typical Application Scenarios

 

This compressor fits small‑scale manufacturing workshops, metal processing, packaging lines, woodworking workshops, general light‑industry factories, and all kinds of pneumatic tool supporting work.
