Mark III Silent
Ideal for intensive use in hot, poorly ventilated environments or in tropical countries. Designed with an improved cooling system and a filtering system with two Hyperfilters, these compressors are powered by an electric motor and equipped with four different pumping units, all in the TPS (Tropical Plus Superdry) version. They are available with function monitoring systems and electrical panel for automatic compressor shutdown.
3-stage high pressure pumping unit.

Purification at the highest level.
Placed after the last compressor separator and before the pressure holding valve, the Hyperfilter purification system enables reliable treatment of the breathing air according to DIN EN 12021¹ when using original filter cartridges. The separator present between the 2nd and 3rd stage of the purification circuit allows to extract the greatest possible humidity. The filtering capacity with inlet air at 20 ° C and 200 bar is 4300 m³.
Electrical cabinet
-
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.
-
Integrated no-load start (automatic drain every time the unit is switched off).
-
5 liter condensate collection tank, with silencer; capacity of about 3 liters, for the ecological disposal of condensate.
-
Interstage pressure gauges display the working pressure for the individual compression stages. This pressure information allows you to check the tightness of the valves (inlet and outlet) of each stage and to quickly identify potential sources of failure.
Chassis
Silenced cab chassis designed and built to facilitate maintenance operations. The tilting motor-holder plate ensures constant V-belt tension. Compressor management and maintenance are facilitated by important devices and tools: the oil level and drain shown outside, the control console equipped with inter-stage pressure gauges, the internal temperature indicator, the presence alarm and incorrect phase sequence, the oil lack alarm and the start stop and manual condensate drain commands.
