Coalescing Filters

Part No: 901566.0

Core Technical Specifications

Required inlet air pre-treatment: Residual liquid oil ≤0.01 ppm 

Adsorption media: High-density food-grade coconut shell granular activated carbon, acid-resistant, anti-hydrolysis, minimal carbon dust shedding

Operating temperature: 3 ~ 66°C; higher temperature accelerates carbon saturation

Max inlet relative humidity: ≤60% RH; dry inlet air extends adsorption cycle significantly

Standard replacement cycle

Clean, low-humidity general workshop: 4000 working hours / 12 months

Paint shop / high humidity / heavy oil load: 1800–2800 hours

Replace trigger: Obvious oily odor at air outlet or ΔP ≥ 0.07 MPa

Differential pressure threshold

Initial new element pressure drop: ≤0.015 MPa

Alarm replacement pressure: ≥0.07 MPa

Structural features

Anti-static conductive plastic cage eliminates static fire hazard in oil-air mixed environments

Key Product Advantages

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 full service cycle. Double-layer microfiber barriers prevent fine carbon dust from entering downstream pipelines.

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

Conductive polypropylene cage dissipates 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  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 Scenarios

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.
