Air Filters

Core Technical Specifications

Absolute Filtration Precision: 3 μm solid particles

Core Function: Remove condensed bulk water, liquid oil droplets, coarse metal dust and pipeline rust particles

Operating Pressure Range: 0.4 ~ 1.6 MPa

Operating Temperature Range: 2°C ~ +60°C

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

High humidity / workshop with heavy dust: 2,500–3,500 hours

Mandatory Replacement Trigger: Differential pressure ΔP ≥ 0.05 MPa

Initial pressure drop of new element: ≤0.010 MPa

Alarm blocking differential pressure: ≥0.05 MPa

Structural Construction Features

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

Outer plastic protective cage prevents fiber media damage during disassembly

Gradient layered structure: large contaminants intercepted by outer layer, extend service life of inner fine media

Hydrophobic fiber design accelerates water/oil droplet aggregation and downward drainage to filter bowl

Key Product Advantages

Ultra-low initial pressure drop for energy saving

Open gradient fiber structure brings low airflow resistance, effectively reducing long-term compressor power consumption.

Front-stage protective effect to extend downstream filter service life

Captures large-volume liquid water, oil and dust, greatly reduce contaminant load of U/H/C precision elements, cut overall filter replacement cost.

Tool-free quick maintenance design

Single worker completes cartridge replacement within 3 minutes, minimize production downtime.

Wide industrial adaptability

Suitable for general machinery, laser cutting, food packaging, textile and pneumatic equipment primary filtration.

Working Principle

Raw compressed air flows from outside to inside through gradient fiber media.

Large solid particles, pipeline rust and coarse dust are intercepted by outer fiber layers.

Liquid water and oil droplets collide with hydrophobic fibers, coalesce into large droplets and drain downwards to filter drain bowl.

Pre-cleaned compressed air flows to U/H/C secondary precision filters for deep purification.

The element cannot be cleaned or regenerated. Once saturated by sludge and dust, full replacement is required.

Application Scope

Metal cutting & welding factories, laser cutting equipment, small plastic injection molding lines, food & beverage packaging pneumatic systems, textile machinery, general machinery processing workshops, pre-filter before painting air pipelines.
