Silicone-free filtration for air compressors

Contact our expert

Guaranteed silicone-free

We produce our SFA filter housings and elements in a clean room environment and clean and test them according to certified procedures.

Energy savings

The design and media used for our compressed air filters minimize reduction in pressure.

Maximum contaminant removal

Our SFA filter ensures maximum removal of dry and wet dust, particulates, oil aerosol and water droplets through its high-efficiency glass fiber and fleece media.

High performance

High-quality materials such as stainless steel cores, double O-rings, epoxy sealed caps and anti-corrosive coated filter housings are selected to ensure high performance and reliability.

Silicone-free filtration for air compressors

An air filter protects your compressed air system and your investment. And there is none better than Atlas Copco’s SFA filters.

These silicone-free air filters efficiently prevent dry and wet dust, particulates, oil aerosol and water droplets from entering your compressed air system. In the process, they ensure that you have access to a compressed air stream with a superb air purity.

Know your air quality requirements

If you know that a filter from the SFA series is right for you, then you can check out the below table for some useful information.

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. If you are not sure which ISO standard applies to your operation, you can contact Atlas Copco or consult this table below.

SFA series

The silicone-free air filters of the SFA series prevent a wide range of contaminants from entering your compressed air system. They not only protect your equipment but also your end products and your entire operation.

Thanks to their glass fiber and fleece filtration media, SFA filters are highly efficient in removing dry and wet dust, particulates, oil aerosol and water droplets. Their low pressure drops ensure that you enjoy significant energy savings while lowering operating costs.

The filters of the SFA series, which are certified by the Fraunhofer Institute as guaranteed silicone-free, stand out with their outstanding reliability. It is the result of high-performance stainless-steel cores, double O-rings, epoxy-sealed caps and an anti-corrosive coated filter housing.

In addition, external ribs on the threaded housing and push-on elements make the filters of the SFA series easy to maintain.

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.
