SILENT


Product description

What you don’t feel it’s his biggest performance.


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.
