Silent reaches new heights in terms of soundproofing, allowing you to drop below the threshold of 70 dB in operation. Built to meet the needs of intensive use and when large refill capacities are required, it is equipped with 4 front filling connections with high pressure hoses and an intuitive control panel. It is also equipped with an electric motor and powerful pumping units. For longer filter life, the Tornado high pressure dryer is recommended. Available as optional: the Presec system for filter saturation control or the SAM system for multigas analysis and remote charging panel.
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.
