SFA series

SFA series - Silicone-Free Filters

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.

Description

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.

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

Silicone free air filter

A guaranteed solution

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.

Air quality requirements

Know your air quality requirements

Air contamination
Air contamination
There are lots of contaminants that threaten your compressed air system – and therefore also your equipment and end products. From wet and dry dust to particulates, water drops and oil aerosols, each of them reduces your air quality and puts your operation at risk.
 
There are lots of contaminants that threaten your compressed air system – and therefore also your equipment and end products. From wet and dry dust to particulates, water drops and oil aerosols, each of them reduces your air quality and puts your operation at risk.

If you know that a filter from the SFA series is right for you, then you can check the specifications table below 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 the table in the filter applications section below.

Filter applications

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.
