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 chassis with vertical development, made for environments that require a low level of noise. The oil level and drain reported outside, the control console equipped with inter-stage pressure gauges, the oil pressure gauge, the internal temperature indicator, the presence alarm and incorrect phase sequence, the lack alarm oil and the start, stop and manual condensate drain commands allow easy management and maintenance of the compressor.
