Less, more.
The best answer to those who want small-sized breathing air compressors, while maintaining high performance. Equipped with four different TPS (Tropical Plus Superdry)
pumping units, Ergo TPS is powered by an electric motor. It has a panel with a monitoring system complete with pressure gauges, autostop with adjustable electronic pressure switch, automatic condensate drain and control of the direction of rotation. It is also equipped with two connections for high pressure hoses and an increased filtering system with two Hyperfilters. Optionally, you can add the remote charging panel.

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.

Open frame designed to facilitate maintenance operations and portability. The tilting motor-holder plate ensures constant V-belt tension. The protective casing in thermo-formed material conveys the cooling air on the cylinders and on the inter-stage pipes, guaranteeing a high compression efficiency. The control console equipped with inter-stage pressure gauges, the internal temperature indicator, the alarm presence and incorrect phase sequence, the oil lack alarm and the start stop and manual condensate drain commands allow easy management and maintenance of the compressor.

Simplicity comes standard.
Imagine having a compressor capable of great performance and endowed with extraordinary solidity. What would all this be without absolute simplicity in
managing it? We believe that innovation is for this: to make everything

The highest air quality is the goal of a Coltri compressor.
Air purity and quality are two essential characteristics of
our compressors. The air you breathe from Coltri
compressors complies with the EN 12021: 2014 standards:
this is why you can work, have fun and exercise with them
in absolute safety.
