Coalescing Filters

Part No: E83KA

Core Technical Specifications

Complete elimination of compressor oil odors, trace volatile organic compounds

Adsorption Media: Food-grade high-specific-surface-area coconut shell granular activated carbon, acid-resistant, anti-hydrolysis, low carbon dust shedding

Continuous Inlet Air Temperature: 3°C ~ 66°C; higher temperature accelerates carbon saturation

Max allowable inlet relative humidity: ≤60% RH

Clean, low-humidity general workshop: 4,000 operating hours / 12 months

Paint shop, high humidity, heavy oil load, 24/7 continuous operation: Shorten service life to 1,800–2,800 hours

Mandatory replacement trigger: Obvious oily odor at air outlet or differential pressure ΔP ≥ 0.07 MPa

Differential Pressure Thresholds

Initial pressure drop of brand-new element: ≤0.015 MPa

Alarm replacement differential pressure: ΔP ≥ 0.07 MPa

Outer Support Cage: Corrosion-proof perforated conductive polypropylene, prevents carbon particle leakage and media deformation under airflow surges

Dual Barrier Layers: Outer & inner microfiber mats fully encapsulate carbon granules to stop carbon dust downstream

Sealing System: Integrated high-temperature EPDM full-circle O-ring, zero bypass air leakage

Anti-Static Design: Conductive composite framework dissipates static charge generated by high-speed air flow and carbon friction, eliminating fire hazards

Key Product Advantages

Terminal polishing stage to achieve odorless, Class 0 oil-free compressed air

Installed downstream of E83KE ultra-coalescing filter, E83KA adsorbs all gaseous oil vapors that glass fiber coalescing media cannot capture. It removes all lubricant odors and trace hydrocarbons, fully protecting high-sensitivity production processes.

High-capacity coconut shell activated carbon with long adsorption service life

Ultra-high specific surface area carbon granules deliver massive oil vapor adsorption capacity, slowing saturation throughout the full service cycle. Double-layer microfiber barriers lock fine carbon dust inside the cartridge to avoid pipeline contamination.

Humidity-resistant media structure to prevent premature carbon failure

Specially engineered anti-hydrolysis carbon formulation tolerates mild condensate exposure; upstream refrigerated/adsorption dryer is mandatory to control inlet humidity below 60% RH and extend service intervals.

Anti-static all-plastic support frame eliminates explosion risk in oil-air mixed environments

Conductive polypropylene cage releases static charge accumulated from high-speed air and carbon particle friction, removing hidden ignition hazards in painting, chemical and food processing workshops.

Tool-free bayonet maintenance design for ultra-fast single-person replacement

No spanner or special tools required; fully vent filter housing pressure, twist open the top bayonet cap, extract old cartridge and install new unit within 1 minute, minimizing unplanned production downtime.

Adsorption Working Principle

Trace gaseous oil vapor, hydrocarbon molecules and odor compounds are captured via physical adsorption on the microporous surface of activated carbon granules.

Purified oil-vapor-free compressed air (total residual oil ≤0.003 ppm) passes through the inner microfiber barrier and flows out to terminal production equipment.

After long-term service, carbon micropores become fully saturated with oil vapors; adsorption efficiency drops sharply and differential pressure rises. The cartridge cannot be regenerated on-site and requires complete replacement.

Application Scope

Automotive electrostatic paint workshops, precision electronic component cleanrooms, cosmetic & pharmaceutical aseptic filling lines, food sterile packaging production, laboratory high-purity instrument gas supply, medical breathing air pretreatment, fiber laser cutting ultra-clean air stations.
