High-Pressure Filtration Solutions
H Series – High-Pressure Filtration
Compressed air systems are inherently subject to contamination risks. Dust, wet dust, oil aerosols, water droplets, particulates, and oil vapors can pose threats to downstream equipment and end products.


Conventional filters can only remove a single set of contaminants at a time. To address this, Atlas Copco has developed the H‑Series high‑pressure air filters, which ensure air purity even at pressures up to 350 bar. These filters efficiently and cost‑effectively remove contaminants in high‑pressure applications.


H Series
This high-pressure filtration solution is meticulously engineered to cost-effectively reduce a wide range of contaminants in compressed air streams. As a result, it delivers optimal air purity and meets stringent quality requirements for operating pressures of up to 350 bar.
All filter housings in the H Series undergo hydraulic testing to ensure safe and reliable operation at all times. Featuring high‑efficiency glass‑fiber and felt media, they deliver maximum removal of dry and wet dust, particulates, oil aerosols, and water droplets—depending on the model you select; please refer to the table below. As a result, the H Series provides robust protection for your compressed air stream, downstream equipment, and end products.
The low pressure drop of these high-pressure air filters can help you save significant energy and reduce operating costs. Moreover, with their high-performance stainless steel filter elements, dual O-rings, epoxy‑sealed end caps, and corrosion‑resistant coated housings, they deliver reliable performance.


Understand your air quality requirements.
If you’re unsure but know you must protect your system, you need to understand your air quality requirements.
Understanding your air quality requirements and the standards you must comply with will help you select the appropriate air filter, thereby reducing your capital costs and ensuring that you can fully leverage your compressed air system.

 

Find the filter that suits your application environment.
The table below shows the various ISO 8573-1:2010 air purity classes, along with the Atlas Copco filter and dryer combinations that meet these classes.
If you’re unsure which ISO class is required but know precisely which contaminants must be kept out of your system, please refer to the general‑purpose and specialized‑application tables below. They provide an overview of which Atlas Copco filter is best suited to address each type of contaminant.
