Coalescing Filters

Part No: E83KD

Core Technical Specifications

Filter Media: Multi-layer deep-pleated imported borosilicate glass fiber composite with integrated polyester drainage fleece, anti-hydrolysis, low permanent pressure loss, static conductive

Max Continuous Working Pressure: 1.6 MPa

Continuous Inlet Air Temperature: 3°C ~ 66°C

Max allowable inlet relative humidity: ≤70% 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 2,000–3,000 hours

Mandatory replacement trigger: Visible liquid carryover downstream or differential pressure ΔP ≥ 0.07 MPa

Initial pressure drop of brand-new element: ≤0.018 MPa

Alarm replacement differential pressure: ΔP ≥ 0.07 MPa

Outer Support Cage: Rigid perforated anti-static polypropylene, corrosion-proof, prevents media deformation under airflow surges

Integrated Drainage Fleece: Polyester drainage layer gathers coalesced liquid and guides it downward to housing condensate drain

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

Anti-Static Design: Conductive composite framework eliminates static charge buildup risk in oil-air mixed working environments

Key Product Advantages

It drastically reduces contaminant load for E83KE ultra-coalescer and E83KA carbon filter, extending their service cycles by over 50% and cutting overall maintenance costs.

Deep-pleated gradient glass fiber media with large liquid holding capacity

Generous pleat surface area provides outstanding water & oil sludge storage capacity, slowing differential pressure rise across the full service life. Built-in polyester drainage fleece continuously drains separated condensate, avoiding secondary liquid re-entrainment by turbulent airflow.

Ultra-low permanent pressure loss reduces compressor energy consumption

Optimized flow channel design and high-permeability media deliver up to 50% lower steady-state pressure loss compared to generic aftermarket filters, lowering continuous power draw of upstream screw compressors and reducing long-term factory electricity expenses.

Anti-static all-plastic support structure eliminates fire hazard in high-oil environments

Conductive polypropylene cage dissipates static charge generated by high-speed air and oil mist friction, removing ignition risks in painting, chemical processing and food manufacturing workshops.

Bayonet plug-and-play maintenance design for rapid single-person replacement

No special tools required; fully vent filter housing pressure, unlock top bayonet cap, extract old cartridge and install new unit within 1 minute, minimizing unplanned production downtime during servicing.

Coalescing Working Principle

Compressed air containing solid dust, bulk water droplets and medium-size oil mist flows out of E83KB particulate filter and enters E83KD outer cage.

Large water and oil droplets are first trapped by the outer polyester drainage fleece and drain downward via gravity to the housing condensate drain port.

Remaining 0.1 μm liquid oil mist penetrates multi-layer gradient glass fiber media; tiny liquid particles collide, aggregate and coalesce into continuous liquid oil films on fiber surfaces.

Pre-cleaned compressed air (≤1 ppm residual liquid oil) passes through the inner barrier layer and flows downstream to E83KE ultra-coalescing polishing stage.

After long-term service, media pores become fully saturated with oil sludge and water deposits; differential pressure rises sharply and separation efficiency drops, requiring full cartridge replacement .

Application Scope

Automotive component electrostatic painting workshops, metal cutting & welding factories, plastic injection molding production lines, food & beverage sterile packaging pneumatic systems, textile factory compressed air supply, small & medium general machinery processing pneumatic tool stations.
