Force Four
The FORCE FOUR model meets professional needs that require large charging capacities in hot, poorly ventilated environments or tropical countries. It is equipped with an intuitive control panel and electric motor. The pumping unit, a choice of 3 most powerful, is exposed to ensure a better cooling cycle. It is equipped with the Hyperfilter purification system mounted on a stand-alone system, with automatic condensate drainage. For longer filter life, the Tornado high pressure dryer is recommended. Available as options: the Presec system for filter saturation control, Megafilter oversized filter cartridges, and 2- or 4-outlet remote refill panel.

Electric motor
One of the fundamental parts of the compressor: the motor transfers the motion to the pumping unit through the belt. Single-phase 7.5 kW or three-phase 7.5 to 11 kW electric motor is available on this model.
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.
Compressor control and automatic condensate drainage system
-
Motor protection switch.
-
Fixed calibration pressure switch 232 or 300 bar.
-
Autostart with pressure differential 15 bar. (optional)
-
Transformer.
-
Drainage of all separators between individual stages and also of the final separator during compressor operation (standard drainage interval every 15 minutes for a period of 6 seconds).
-
Timer for automatic condensate drain.
-
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.
Interstage pressure gauges are mounted in the compressor frame.
