Compressor Open MCH 22, 30 and 36 Coltri

Open satisfies the professional needs they require

Large charging capacities in hot, poorly ventilated environments

or tropical countries. It is equipped with 4 front attachments of

filling for high-pressure hoses, of a

Intuitive control panel and electric motor. The

pumping unit, to be chosen from the 4 most powerful, is exposed

at the rear of the structure to ensure a

best cooling cycle. For a longer service life

of the filters, the high-pressure dryer is recommended

Tornado. Available as an option: the Presec system for the

filter saturation control or the S.A.M. system for

the multi-gas analysis and remote charging panel.

4-stage high-pressure pumping unit.

Oil level sensor

Prepared for Hyperfilter filter system

Purification at the highest level.

Placed after the last compressor separator and before the pressure maintenance valve, the Hyperfilter purification system enables reliable treatment of breathing air, according to DIN EN 12021¹ when using original filter cartridges. The separator between the 2nd and 3rd stages of the purification circuit allows the extraction of as much moisture as possible. The filtering capacity with incoming air at 20°C and 200 bar is 4300 m³.

Electrical panel

ON/OFF switch with motor protection switch.

Digital electronic pressure switch that stops the compressor at the final pressure.

Drainage of all separators between the individual stages and also of the final separator during compressor operation

Timer for automatic condensate drain.

Built-in no-load start (automatic drain each time the unit is switched off).

5 litre condensate collection tank, with silencer; Capacity of approx. 3 litres, for environmentally friendly condensate disposal.

Interstage pressure gauges display the operating pressure for individual compression stages. This pressure information allows you to check the tightness of the valves (inlet and outlet) of each stage and quickly identify potential sources of failure.
