The Coltri MCH 11/EM Compact Breathing Air Compressor gives the performance required of a dive shop or dive club breathing air compressor from a unit able to operate off a single phase supply. The compressor is powered by a 4Kw single phase motor so will require it's own dedicated supply but eliminates the expense of installing a three phase supply into your premises.

The compressor is capable of producing 195 L/min (7 CFM) meaning a fill time of around 11 minutes for a 15 litre cylinder from empty to 200 Bar. Filtration to supply air quality to EN12021, fill whip assembly and choice of fill adaptors are supplied as standard. The Compact compressor has auto stop and automatic condensate drains.
