Description
The FORCE FOUR by Coltri Compressor is tailored to meet the demands of professionals operating in challenging conditions, such as hot and poorly ventilated environments or tropical regions, where substantial charging capacities are essential. This model comes equipped with an intuitive control panel and an electric motor for seamless operation.
To enhance cooling efficiency, the pumping unit, with a selection of three of the most powerful options, is prominently exposed. Additionally, it features the Hyperfilter purification system, which is integrated into a stand-alone configuration, complete with automatic condensate drainage for optimal performance.
For extended filter longevity, we recommend considering the Tornado high-pressure dryer as an accessory. Furthermore, this model offers various optional features, including the Presec system for monitoring filter saturation, Megafilter oversized filter cartridges, and a 2- or 4-outlet remote refill panel, providing versatility to suit your specific requirements.
Available models:
- 400 EM
- 450 ET
- 650 ET

Electric motor
A key part of the FORCE FOUR compressor is the motor. 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 for the most efficient extraction of 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.
