• Aluminum monoblock
• Forced lubrication with low-pressure gear pump
• First stage for gas recovery
• Pipes, fittings and nuts made of AISI 316 stainless steel
• Intermediate condensate separators after the second and third stages
• High-pressure final condensate separator
• Safety valves after each compression stage
• Special cast iron cylinders with low roughness lapping
• Forged aluminum connecting rods
• Forged steel crankshaft
• First-, second- and third-stage high-flow fill valves
• Heavy-duty roller bearings
• Hardened steel fourth stage with 6 special cast iron piston rings
• Second and third stages with thrust pads to eliminate lateral forces on the pistons
• Filter system Hyperfilter activated carbon

One of the key parts of the compressor: the motor transfers motion to the pumping unit through the belt. The three-phase electric motor is available on this model from 11 to 1 5 kW.

Placed after the last compressor separator and before the pressure maintenance valve, the purification system Hyperfilter 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 stages of the purification circuit makes it possible to extract as much moisture as possible. The filtering capacity with inlet air at 20°C and 200 bar is 52,500 m³.

• ON/OFF switch with motor protection switch.
• Electromechanical pressure switch that stops the compressor at the final pressure.
• Drainage of all separators between individual stages and also of the final separator during compressor operation
• Timer for automatic condensate drainage device.
• Integrated no-load startup (automatic discharge each time the unit is turned off).
• Condensate collection tank 5 liters, with silencer; capacity about 3 liters, for environmentally friendly disposal of condensate.
• Interstage pressure gauges display the operating pressure for individual compression stages. This pressure information allows the tightness of the valves (inlet and outlet) of each stage to be checked and potential sources of failure to be quickly identified.

Silenced cabin chassis with vertical development, made for environments requiring low noise level. Oil level and drain reported externally, control console equipped with inter-stage gauges, oil pressure gauge, internal temperature indicator, presence and wrong phase sequence alarm, oil shortage alarm, and run stop and manual condensate drain controls allow easy operation and maintenance of the compressor. Made of steel with scratch-resistant powder coating in color Black RAL 9005.
