The Coltri MCH 11 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.
