Coalescing Filters

Core Technical Specifications

Filtration Grade: Terminal vapor adsorption polishing stage, eliminates compressor oil vapor, hydrocarbon gases and oily odors

Removal Performance

Adsorption Media: High-density food-grade granular coconut shell activated carbon, acid-resistant, anti-hydrolysis, ultra-low carbon dust shedding

Max Continuous Working Pressure: 1.6 MPa

Operating Temperature Range: 3°C ~ 80°C; higher temperature drastically accelerates carbon saturation

Max Inlet Relative Humidity: ≤60% RH; dry inlet air extends adsorption service cycle significantly

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

Mandatory Replacement Trigger: Obvious oily odor at air outlet or differential pressure ΔP ≥ 0.07 MPa

Initial Pressure Drop of Brand-New Element: ≤0.015 MPa

Alarm Replacement Differential Pressure: ΔP ≥ 0.07 MPa

Perforated stainless steel inner & outer support cages, anti-rust and anti-corrosion, prevents carbon core deformation under large-volume high-speed airflow surges

Dual inner & outer microfiber barrier mats fully encapsulate carbon granules to block fine carbon dust from entering downstream pipelines

Double full-circle oil-resistant EPDM sealing rings, zero bypass air leakage

Static conductive composite framework eliminates static accumulation fire risk in oil-air mixed working environments

Key Product Advantages

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

Installed downstream of HF0440 ultra coalescer, CF0440 adsorbs all gaseous oil vapors that glass fiber coalescing media cannot capture, removes lubricant odors and trace hydrocarbons, fully protecting high-sensitivity precision mass 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 and equipment failure.

Humidity-resistant media structure to prevent premature carbon failure

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

Stainless steel anti-corrosion framework adapts to harsh heavy industrial environments

Full stainless steel support cages resist rust and condensate corrosion, suitable for long-term continuous operation in large auto painting, heavy laser cutting, pharmaceutical mass filling and food packaging workshops.

Threaded quick-install design for single-person fast maintenance

Isolate and vent housing pressure, unscrew the top threaded cap, extract old cartridge and install new unit within 3 minutes, minimizing unplanned large-scale 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 high-precision 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 large-component electrostatic painting workshops, heavy-duty metal fiber laser cutting factories, large electronic component cleanrooms, cosmetic & pharmaceutical mass aseptic filling lines, large food sterile packaging production, central laboratory high-purity instrument gas supply, medical central breathing air pretreatment.
