E-book Compressed Air Filters
23 May, 2022
Filters play a crucial role in the proper treatment of compressed air. In this interactive e-book on filters you will learn everything on contaminants and which filters offer you optimal protection.
H series
High pressure filtration
H series - High pressure filtration
Compressed air systems are always at risk of contamination. Dust, wet dust, oil aerosol, water droplets, particulates and oil vapor pose a threat to downstream equipment and end products.

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.
Know your air quality requirements
If you are unsure, and only know that you have to protect your system, then you need to find out your air quality requirements.
Knowing your air quality requirements and which standards to comply with will help you select the right air filter, which could lower your investment costs and ensure that you get the most out of your compressed air system.
Air quality requirements
Find the right filter for your application
The table below shows the various ISO 8573-1:2010 air purity classes and the Atlas Copco filters and dryer-combinations that meet these classes.
If you are unsure which ISO class you need but you do know what contaminant you have to protect your system from, then check out the general and special applications tables below. It will provide you with an overview of which Atlas Copco filters are the ideal solution for which contaminant.
