Breathing Air Compressor SUPER SILENT 235 L/min, 400 V 50 Hz

Low-noise high-pressure breathing air compressor for professional filling stations

The Coltri Super Silent is a stationary high-pressure breathing air compressor with a soundproofed steel enclosure, designed for continuous operation in dive centers, clubs, fire departments, and industrial applications.

The fully enclosed design significantly reduces noise emissions and allows operation even in noise-sensitive environments. At the same time, the system provides a robust compressor unit, reliable cooling, and comprehensive safety monitoring.

The integrated Maxi Filter purification system ensures breathing air in accordance with EN 12021. The compressor is also compatible with Nitrox (up to 40% O), helium, and nitrogendepending on configuration and version.
