Coalescing Filters

Core Technical Specifications

Pre-filtration Precision: 0.01 μm solid particles & residual liquid oil aerosols

Composite Media Structure: Outer borosilicate glass fiber coalescing pre-layer + inner food-grade granular activated carbon core; hydrolysis-resistant, compatible with all mineral and synthetic compressor coolants

Standard Replacement Interval

Clean indoor workshop, inlet temp ≤100°F: 1,000 operating hours or 12 months

High oil load / painting workshop, inlet temp >100°F: 500–800 hours

Mandatory Replacement Trigger

Differential pressure ΔP ≥ 0.05 MPa or obvious oily chemical odor detected in downstream pipelines

Differential Pressure Thresholds

Initial pressure drop of new element: ≤0.014 MPa

Blockage alarm differential pressure: ≥0.05 MPa

Key Product Advantages

Dual-layer composite design extends carbon service cycle

Outer glass fiber pre-layer intercepts residual liquid oil mist and micro dust before air enters carbon core, preventing carbon micropore clogging and doubling adsorption service life.

High-capacity macro-pore activated carbon for stable long-term adsorption

Uniform large-pore carbon granules provide massive oil vapor storage capacity; differential pressure rises slowly without sharp resistance surge under continuous heavy-duty operation.

Full perimeter dual-end rubber sealing eliminates bypass airflow

Molded black rubber end caps with embedded nitrile O-rings block short-circuit unfiltered air, ensuring 100% compressed air passes through activated carbon for complete odor & vapor removal.

Working Principle

Ultra-clean compressed air pre-treated by FE100-A coalescing filter flows from inside to outside through glass fiber pre-layer.

Trace residual liquid oil droplets and micro solid dust are captured by the outer coalescing media and drain down to the filter bowl via gravity.

Liquid-free clean air enters the activated carbon core; oil vapor, hydrocarbon gas and oily odor molecules are physically adsorbed into carbon micropores.

Odorless, ultra-dry Class 1 oil-free compressed air is delivered to terminal production equipment.

Activated carbon will reach adsorption saturation after long-term operation. This filter element cannot be cleaned, regenerated or reused; full replacement is required once saturated.

Application Scope

Automotive electrostatic painting workshops, precision electronic component assembly, pharmaceutical sterile production, medical dental air supply, food sterile packaging, laboratory analytical instruments, laser cutting & laser marking equipment.
