Description

Regular filters that take on one group of contaminants each, Atlas Copco has also developed high-pressure air filter variants that guarantee air purity up to a pressure of 350 bar: The H series. They efficiently reduce contaminants in a high-pressure environment in a cost-effective manner.

H series

This high-pressure filtration solution has been engineered to cost-effectively reduce a wide range of contaminants in your compressed air stream. As a result, they provide you with the best air purity and meet even stringent quality demands for working pressures of up to 350 bar.

All filter housings of the H series are hydraulically tested to ensure a safe and reliable operations at all times. Using high-efficiency glass fiber and fleece media, they ensure a maximum removal of dry and wet dust, particulates, oil aerosol and water droplets (depending on which model you choose. Please consult the table below). As a result, the H series provides optimal protection for your compressed air stream, downstream equipment and end products.

The low pressure drops of these high-pressure air filters offer you substantial energy savings and lower operating costs. In addition, thanks to high-performance stainless-steel cores, double O-rings, epoxy-sealed caps and a filter housing with an anti-corrosive coating, they are also extremely reliable.
