Why do I need a compressed air filter?

Compressed air filters help to keep the air clean and condensate free to protect equipment from dust, dirt, pipe scale, oil and water. Even though the compressed air system will typically have a main dryer, additional treatment is often necessary. For this discussion, we will focus on the oil removal process and filter type.

Why do I need an oil-water separator for my air compressor?

The oil-water separator collects condensate from your air compressor, tank, filters, and dryer, and removes the oil from the water prior to putting it down the drain. It also eliminates the need to have the oily condensate hauled away. Why Do I Need an Oil/Water Separator for My Compressed Air System?

What does an air compressor oil filter look like?

Typically, an air compressor oil filter looks like a can with openings on one side. Inside the filter is a paper filter element which is folded like a harmonica to create the biggest possible surface area (so that maximum oil can flow through). But be aware: not all air compressor oil filters are the same! Oil filters on rotary screw compressor

Can dust damage air compressor oil filter?

Dust and dirt will damage the filter element, wear the bearings and clog the oil-separator. Typically, an air compressor oil filter looks like a can with openings on one side. Inside the filter is a paper filter element which is folded like a harmonica to create the biggest possible surface area (so that maximum oil can flow through).

What is an oil filter on a compressor?

Oil filters are normally only found on bigger compressors, like oil-injected screw compressors. Obviously, they filter the oil to remove any dirt. In other words: they protect your compressor from damages by dirt, sand, pieces of rust, etc. Dust and dirt will damage the filter element, wear the bearings and clog the oil-separator.

How does a two-stage compressed air filter work?

Two-stage filtration in compressed air filters, such as those from ASCO Numatics, works by removing large particles in the first stage and fine particles in the second stage. This is equivalent to having two filters in one, and also removes water droplets and oil.
