Compressed Air & Gas Filters

Our 300 series of high efficiency coalescing compressed air & gas filters are designed for versatility. The many features provide complete protection for instrumentation, pneumatic machinery, fuel gas systems, air dryers as well as a vast array of process applications. At the heart of our coalescing filter is the completely disposable C-type coalescing element. Made entirely from borosilicate glass microfiber and fluorocarbon binder, it is compatible with all compressor lubricants and will operate at temperatures up to 300°F. The C-type element has a two-layer structure, an inner particle capture-layer and an outer drainage-layer. Liquid droplets remain mobile once captured and travel through the fine-pored capture-layer, along the intersecting microfibers, growing in size as they progress. These coalesced droplets are transferred to the large-pored drainage-layer from where they drain by gravity into the filter bowl. Liquid collected in the filter bowl can be removed by a manual or fully automatic drain.

Each filter assembly comes complete with a coalescing element. Simply designate your grade when ordering: I.E. 360A-1/2”-70C.
HOW TO SELECT THE CORRECT COALESCING GRADE OF FILTER ELEMENT
GRADE 70C -
COALESCER
HIGH EFFICIENCY
Has an efficiency rating of 95% against 0.01 micron particles and aerosols and should be specified for all general purpose applications requiring clean compressed air. e.g. Protection of valves, cylinders, air tools, air motors and pumps etc. This element is ideal for fuel gas/CNG filtration. It provides excellent efficiency while allowing high flow rates.
GRADE 50C –
COALESCER
HIGH EFFICIENCY
Has an efficiency rating of 99.99% against 0.01 micron particles and aerosols and should be specified for the most demanding applications requiring the highest quality of air cleanliness. e.g. air bearings, spray coating, instrumentation, laser systems, food contact etc. For best performance a grade 70C coalescer should be used as a pre-filter to the grade 50C.
HOW TO SELECT THE CORRECT NON-COALESCING FILTER ELEMENT
GRADE PEL –
POLYETHYLENE
BULK CONTAMINATES
In compressed air & gas service, the sintered polyethylene (PEL) elements may be utilized as pre-coalescers or initial course filters in heavily contaminated systems. They can assist and improve the longevity of a coalescing element to capture fine aerosols. The 75-micron grade is recommended for this task since it exhibits the best flow curves. Micron sizes available: 10, 25, and 75.
*These are not included with 300 series housings. Sold Separately.
GRADE SS –
STAINLESS STEEL –
RECLEANABLE
In compressed air & gas service, the mesh stainless steel (SS) elements may be utilized as pre-coalescers or initial course filters in heavily contaminated systems. The SS elements may also be cleaned for reuse. Micron sizes available: 0.5, 1, 3, 10, 25, 50, 100, and 200.
*These are not included with 300 series housings. Sold Separately.
GRADE CC –
OIL VAPOR ADSORPTION
CRITICAL APPLICATIONS
Coalescing filters can only remove oil and water present in compressed air lines as liquid aerosols. They cannot remove the small fraction of oil present as a true vapor. We provide carbon (CC) based vapor adsorption cartridges, which will remove hydrocarbon vapor when used in conjunction with coalescing filters. Please remember a 50C coalescing prefilter must always protect grade CC Hydrocarbon Vapor Adsorption Cartridges. The CC cartridges have the same Flow rate as 50C elements.
*These are not included with 300 series housings. Sold Separately.
GRADE SG –
H20 VAPOR ADSORPTION
CRITICAL APPLICATIONS
Coalescing filters can only remove oil and water present in compressed air lines as liquid aerosols. They cannot remove the small fraction of water present as a true vapor. We provide silica gel (SG) based vapor adsorption cartridges, which will remove water vapor when used in conjunction with coalescing filters. Please remember a 50C coalescing prefilter must always protect grade SG Water Vapor Adsorption Cartridges. The SG cartridges have the same Flow rate as 50C elements.
*These are not included with 300 series housings. Sold Separately.
