Outer Drainage Layer: Drainage of coalesced liquid and protection from re-entrainment is provided by a polymeric outer drainage layer. This ensures consistent, high efficiency performance.
Metal Support Core: Axial strength and protection against liquid slugs are provided by a perforated inner support core constructed of
304 stainless steel.
Outer Cage: Media support during operation is provided by a 304 stainless steel outer support cage.
Primary Coalescer: Coalescing is achieved by use of a high area pleated glass fiber medium that is surrounded by a non-woven polymeric support and drainage layers. A patented surface treatment is used that enhances coalescer performance and lowers fouling tendency and pressure drop.
End Caps: 304 stainless steel end caps are used to improve cartridge strength and prevent contaminant bypass.

1 Standard seal material is Nitrile (H13). Fluorocarbon Elastomer (H) and Ethylene Propylene (J) are also available for optimum fluid compatibility.
2 A change out differential pressure of 15 psid is recommended to ensure efficient operation.
& Drain Sizes
- Removal of 99.99% of all aerosols 0.3 microns and larger. Typical downstream aerosol concentrations are less than 0.003 ppm.
- Patented surface treatment that prevents liquids from wetting the coalescer media allowing for higher gas flow capacity and lowered fouling tendency and differential pressure.
- Consistent performance using thin fibers and fixed pore construction optimized for efficient coalescing.
- Long service life due to pleated media structure and surface treatment.
- Low energy losses with typical saturated pressure drop of 1.2 psid (82.7 mbard).
- Wide range of compatibility for use with process gases, compressor oils, hydrocarbon condensates, and water.
To calculate the pressure drop for other process conditions use the
∆P = KH QA2 ρ + KC QA µ
|where:||∆P:||pressure drop in psid|
|KH:||housing pressure drop constant|
|QA:||actual flow rate in acfm|
|ρ:||gas density at operating conditions in lb/ft3|
|KC:||coalescer pressure drop constant|
|µ:||gas viscosity at operating conditions in cP|
