Filter Cylinders

Did you know that cylindrical filters are made of polyester felt that's been treated with resin then baked in an oven?  The oven curing helps to provide the tell-tale rigidity that makes these filters self supporting. Which means there is no need for support screen or springs with cylindrical filters, they stand tall on their own. The most common pore size is a 40 micron for this particular type of oil coalescing filters. However, cylindrical filters can be made in a variety of micron ratings.

Applications for filter cylinders include:

• Breather filters on military equipment
• Air filters prior to air compressors
• Oil coalescing filter
