Coalescing Filter Element
Stainless Steel Industrial Air Filter Element.A coalescing filter element is a high-efficiency filtration component designed for liquid-liquid separation. Its primary function is to coalesce emulsified and free water in oil into larger droplets and then separate them. The coalescing layer merges fine water droplets into larger ones, while the hydrophobic separating layer blocks water passage, achieving effective oil-water separation. It is widely used for oil dehydration and purification.Stainless Steel Industrial Air Filter Element.
Product Features
High coalescing efficiency – reduces free water content to below 15ppm in a single pass
Low initial pressure drop, reducing operating energy consumption
High dirt-holding capacity for extended service life
Excellent corrosion and temperature resistance, suitable for various oil types
Compact design for easy installation and replacement
Applications
Dehydration of aviation fuels (Jet A, Jet A-1, JP series)
Water removal from diesel, gasoline, and biodiesel
Online water removal for lubricating oil, turbine oil, and hydraulic oil systems
Insulation recovery treatment for transformer oil
Phase separation of petrochemical process liquids (e.g., benzene, alcohols, solvent oils)
Marine fuel and lube oil purification systems
Lubricating oil recovery in natural gas compressors
Service Life
Under normal operating conditions: 6–24 months
Replacement indicators:
Differential pressure reaches 1.5–2.0 bar (alarm value)
Persistent water content exceedance at outlet
Excessive solid particle contamination after filtration
Recommended service period reached per company policy
Features
High pollution capacity Imported filter materials are selected, which can accommodate high quality particle pollution per unit area, large pollution capacity, and long service life.
Stable filtering accuracy Good processing technology reduces the damage of filter materials caused by mechanical force during wave bending processing, which can cause filtration failure andensure stable and uniform filtration accuracy of the filter element.

FAQ
Q: What impurities can the coalescing filter element remove?
A: It primarily removes emulsified and free water from oil, while also capturing a certain amount of solid particles.
Q: How to determine when the filter element needs replacement?
A: Typically by pressure differential (reaching alarm value), excessive water content after filtration, or reaching the recommended service period.
Q: Is the filter element compatible with different brands of filter housings?
A: Compatibility depends on dimensions, port type, and seal design. Customization is available upon request.
Q: What materials are used in the filter element?
A: The coalescing layer is usually fiberglass or special resin; the separating layer is stainless steel mesh or hydrophobic material. End caps and cages are often carbon steel or stainless steel.
Q: Does high temperature or high-viscosity oil affect performance?
A: Yes, to some extent. Please provide your operating conditions so we can recommend a suitable model with adequate temperature or viscosity tolerance.
