Mistral Series High Pressure

The Opus Mistral Series is a range of high-pressure portable breathing-air charging sets.

They are high pressure breathing air charging sets that makes cylinder charging possible, where and when you need it. This set comprises of a three stage air cooled compressor, driver and purification system, which incorporates a coalescing prefilter (0.5 mg/m3 oil residual) located prior to the purification cartridge, ensuring breathing air that exceeds the EN 12021 directive.

It’s lightweight, compact and easy to transport, as wheels are mounted on the base. The very slow compressor speed ensuresreliability and long life.

Several models are available, with a choice of electric motor (single or three phase) or petrol engine drives.
