Oil Free Air Compressors

Oil Free Air Compressors

As well as manufacturing one of our standard air compressors as an oil-free version (SEP550S/OF), the SEP400 compressor is also oil-free and designed for pre-action systems where lower pressures and volumes are required but quiet operation is essential. For example, computer rooms, office suites, residential applications etc.

The SEP400 unit is suitable for continuous operation, and as the compressor is oil free it is very low maintenance. Higher capacity models are available to order.

All of our compressors are designed to comply with LPC, BS5306 & EN12845 guidelines, all materials comply with PED 97/23/EC and are fully tested prior to packing and despatch.
