Filtermart™ Coalescer Filters : Air

Borosilicate Glass Coalescer Filter Solutions

Borosilicate glass coalescer filters are commonly specified for fine liquid-aerosol removal, with some elements rated to capture entrained liquids down to approximately 0.01 microns. The glass-fiber matrix captures oil mist and water aerosols and coalesces them into larger droplets, which are directed toward the drainage layer for removal from the air stream.

Low initial resistance is also important in a coalescing application. A properly selected glass fiber filter element can help limit unnecessary pressure drop, support efficient airflow, and reduce the amount of compressor work required to maintain downstream flow.

Borosilicate Glass Filters for Industrial Applications

• Pharmaceutical and food-grade compressed-air systems where clean air is critical to the process
• Electronics manufacturing and cleanroom-adjacent applications sensitive to aerosol and particulate contamination
• Petrochemical and gas-processing systems requiring consistent oil-mist and moisture removal upstream of instrumentation
• Industrial plants protecting pneumatic tools, valves, controls, and other downstream equipment from liquid contamination

Why Choose FilterMart for Borosilicate Glass Filter Elements

FilterMart supports borosilicate glass filter elements with more than 1,137,727 cross-references, helping customers identify replacement elements for existing housings and part numbers. Proper dimensional matching is important because an incorrect fit can create bypass paths and reduce filtration performance.

Not every application requires the same media. For liquid-service applications, compare our liquid coalescer filters for separation needs involving fuel or hydraulic fluids. For applications where solid-particle loading is the primary concern, borosilicate particulate elements or paper particulate coalescer filters may be more appropriate. Our air coalescer filters category provides a practical starting point for comparing available filtration options.

Frequently Asked Questions

What is a borosilicate glass coalescer filter used for?

It is used to remove fine oil mist, water aerosols, and other liquid contaminants from compressed-air or gas streams. This helps protect downstream equipment and supports cleaner air for sensitive industrial processes.

How is a borosilicate glass fiber filter different from a standard particulate filter?

A standard particulate filter primarily targets solid debris. A borosilicate glass fiber filter is designed for coalescing liquid droplets, combining smaller droplets into larger droplets that can drain from the airstream.

What efficiency can I expect from a borosilicate filter?

FilterMart's borosilicate glass elements are engineered for fine liquid-aerosol capture, with the supplied specifications indicating performance down to approximately 0.01 microns for entrained liquids.

Will a glass fiber filter element fit my existing housing?

Compatibility depends on the housing dimensions and part number. FilterMart cross-references borosilicate glass cartridges against major OEM dimensions to help identify suitable replacement elements without changing the existing housing.

How often should a silicate filter element be replaced?

Replacement intervals depend on contamination loading and differential pressure rather than a fixed calendar schedule. Monitoring pressure drop and following the applicable manufacturer's recommended replacement limit can help maintain filtration performance and manage energy use.

Do borosilicate glass coalescer filters need special handling?

Yes. Fine glass-fiber media should be handled carefully during installation and removal to avoid crushing the element or damaging its end caps. Used cartridges should be disposed of according to your facility's applicable filter-waste procedures.

Is a silicate filter the same as a borosilicate glass filter?

In this page's filtration terminology, "silicate filter" is used as a shorthand reference to borosilicate glass filtration media. The more precise term for this application is borosilicate glass filter or borosilicate glass fiber filter.
