Breathing Air System for 4 users filter

Åndemiddel Filter

Air-Fed air from the air compressor can be used where there is a low oxygen concentration (less than 17% vol.) Or the ambient air is not suitable for breathing air.

Ultrafilters breathing air panel with SMF & AK filter (oil and particle filter and carbon filter) is used for filtration of compressed air from the compressor, this product is available in two versions floor stand or wall mounting with 1-4 connections.

The Danish working environment authority has prepared an AT-guidance regarding Compressed air breathing apparatus D. 5.1 by July 2000.

AT manual describes in requirements for breathing air quality. It also commands a check of this (should be at least 1 time per year).
