Compressor Belts

Core Technical Specifications

Separation precision: Captures ultra-fine oil aerosols as small as 0.1 μm

Residual oil content at compressor outlet: ≤3ppm

Oil mist separation efficiency: ≥99.99% for particles ≥0.1 μm

Media property: Hydrophobic & oleophobic high-temperature resistant glass fiber, compatible with all mineral and synthetic compressor lubricants

Operating pressure range: 0.4 ~ 1.6 MPa

Standard Replacement Cycle

Clean indoor workshop with stable continuous load: 3,500–6,000 operating hours or 12 months (whichever comes first)

Dusty workshop, frequent start-stop & heavy intermittent load: Max 3,500 hours

Mandatory Replacement Criteria

Differential pressure of separator ≥0.08 MPa, or obvious excessive oil consumption, oily fog and liquid oil droplets flowing out from terminal compressed air pipelines

Initial pressure drop of new separator: ≤0.02 MPa

Blockage alarm differential pressure: ≥0.08 MPa

Product Advantages

Adopts US HV ultra-fine glass fiber composite material, maintains stable oil removal efficiency under continuous 120°C high-temperature working condition, no media softening or secondary oil re-entrainment.

Independent central vertical oil return tube design

Coalesced liquid lubricant drains rapidly back to compressor oil sump via dedicated central tube, effectively reducing unit oil consumption and cutting frequent oil refilling costs.

Double-layer metal mesh anti-collapse protection structure

Internal and external perforated steel support mesh prevents fiber media deformation under long-term negative airflow pressure, maintaining stable separation efficiency throughout full service life.

Integrated one-piece NBR threaded sealing ring

Heat-resistant NBR rubber gasket fully bonded to threaded base, eliminates oil leakage at threaded joints under high temperature and pressure, lowering routine maintenance frequency.

Working Principle

High-temperature oil-air mixed gas discharged from screw rotors enters the separator canister from outside to inside.

Large liquid oil droplets sink to the bottom of the canister for primary gravity separation.

Ultra-fine 0.1 μm oil aerosols collide with multi-layer gradient glass fiber media, coalesce into large liquid oil droplets and flow down to the central oil return tube.

Clean compressed air without oil mist flows out from the top of separator to post-treatment dryers and precision pipeline filters; recovered lubricant flows back to compressor oil sump for recycling.

The filter media cannot be cleaned, washed or regenerated. Full canister replacement is required once saturated by carbon sludge and oil contaminants.

Application Scope

Automotive component manufacturing workshops, general machinery processing, plastic injection molding lines, textile pneumatic equipment, food packaging air supply, small mobile construction air stations, laboratory and pharmaceutical factory compressed air systems.
