Air Filters

Core Technical Specifications

Absolute Filtration Precision: 0.01 μm submicron particles

Particle Removal Efficiency: ≥99.999% for contaminants ≥0.01μm

Operating Temperature Range: +1.5°C ~ +80°C

Filter Media: Multi-layer hydrophobic & oleophobic borosilicate glass fiber composite, hydrolysis-resistant, compatible with all compressor mineral/synthetic coolants

Standard Replacement Cycle

Clean indoor workshop: 4,000–6,000 operating hours or 12 months

Heavy oil load / automotive painting line: 2,500–3,800 hours

Mandatory Replacement Trigger: Differential pressure ΔP ≥ 0.05 MPa or visible oil contamination downstream

Differential Pressure Thresholds

Initial pressure drop of new element: ≤0.012 MPa

Alarm blocking differential pressure: ≥0.05 MPa

Structural Construction Features

Central threaded stud for stable vertical locking inside housing, prevents element shaking under airflow

Dual-end integrated sealing gaskets eliminate air bypass and short-circuit filtration

Ribbed drainage structure accelerates liquid oil/water dripping into filter bowl, avoids media saturation

Anti-corrosion plastic end caps & outer cage, suitable for high-humidity industrial environments

Key Product Advantages

Ultra-clean 0.01μm filtration meets high-standard compressed air requirements

Captures invisible micro oil mist and fine dust, delivers Class 1 clean air for laser, electronics and pharmaceutical production.

Low stable pressure drop reduces compressor energy consumption

Uniform gradient fiber layout ensures slow pressure rise throughout service life, cutting long-term power costs.

Fast, tool-free maintenance design

Single person completes replacement within 2 minutes by loosening central stud, minimal production downtime.

High dirt holding capacity extends service interval

Multi-layer deep-pleated media stores large volume of oil sludge and dust, reducing frequent replacement frequency.

Working Principle

Pre-filtered compressed air carrying submicron oil aerosol and fine dust flows from outside to inside through filter media.

Coarse liquid droplets and large particles are trapped by outer pre-layer and drain downwards to filter bowl.

0.01μm ultra-fine oil mist collides with glass fiber media, coalesces into large liquid oil droplets and flows down for drainage.

Ultra-dry, oil-free clean compressed air exits from central core to downstream equipment.

Filter media cannot be cleaned or regenerated; once saturated by oil contaminants, full replacement is required.

Application Scope

Automotive electrostatic painting workshops, precision electronic component assembly, pharmaceutical sterile production, small laser marking/cutting machines, laboratory gas supply, food sterile packaging, medical dental air systems.
