Coalescing Filters

Part No: E31175X1

Core Technical Specifications

Absolute Separation Precision: 0.01 μm ultra-fine liquid oil mist droplets

Removal Efficiency: 99.999% capture rate for all liquid particles ≥0.01 μm

Filter Media: Imported UK HV gradient borosilicate glass fiber composite, oleophobic & hydrophobic, anti-hydrolysis, static conductive, 96% high porosity

Max Continuous Working Pressure: 1.6 MPa

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

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

Paint shop, high humidity, heavy oil load, 24/7 continuous operation: Shorten to 2,000–3,000 hours

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

Differential Pressure Thresholds

Initial pressure drop of brand-new element: ≤0.02 MPa 

Alarm replacement differential pressure: ΔP ≥ 0.07 MPa

Stainless steel perforated support cages, anti-corrosion, prevents media deformation under large airflow surges

Outer polyester drainage fleece: gathers bulk condensed water/oil and guides downward to housing drain port

Double EPDM oil-resistant O-ring top seal, zero bypass air leakage

Static conductive fiber media eliminates static charge buildup fire risk in oil-air mixed environments

Key Product Advantages

Oversized deep-pleated gradient glass fiber media with massive contaminant holding capacity

Large pleat surface area provides outstanding oil sludge & water storage capacity, slowing differential pressure rise over full service life. Layered coalescing structure continuously aggregates micro oil droplets into liquid film for automatic gravity condensate drainage, maintaining stable ultra-high separation efficiency without performance decay.

Ultra-low permanent pressure loss reduces large compressor energy consumption

High-porosity imported glass fiber media delivers up to 50% lower steady-state pressure loss than generic aftermarket filters, lowering continuous power draw of upstream large screw compressors and factory long-term electricity expenditure.

It limits liquid oil content below 0.01 ppm, extending downstream E31175XA carbon filter service life by over 60% and cutting overall maintenance cost.

Stainless steel anti-corrosion framework adapts to humid industrial environments

Full stainless steel support cage resists rust and condensate corrosion, long service life under workshop high-humidity working conditions; static conductive fiber eliminates hidden ignition hazard in paint, chemical and food production workshops.

Simple threaded maintenance design for single-person replacement

Isolate & vent housing pressure, unscrew top cap, extract old cartridge and install new unit within 2 minutes, minimizing unplanned large-scale production downtime.

Coalescing Working Principle

Pre-cleaned compressed air (≤1 ppm liquid oil) from E31175X5 medium coalescer enters outer polyester drainage fleece layer; large water/oil droplets separate and drain downwards via gravity.

Remaining 0.01 μm submicron liquid oil mist penetrates multi-layer gradient glass fiber media; tiny oil particles collide, aggregate and coalesce into continuous liquid oil films on fiber surfaces.

Fully polished compressed air (≤0.01 ppm residual liquid oil) passes through inner microfiber barrier layer and flows out to E31175XA activated carbon final stage for oil vapor & odor removal.

Media cannot be cleaned or regenerated on-site; once saturated with oil sludge, differential pressure spikes and separation efficiency fails, requiring full cartridge 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.
