Coltri Silent
Control is everything.
4-stage high pressure pumping unit.
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.
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.
