Key Product Features

Frontline System Barrier Protection

As the first stage purification barrier in the compressed air pipeline system, it intercepts pipeline rust, scale, workshop dust, massive condensed condensate and bulky oil droplets. It greatly reduces contaminant load for downstream medium coalescing, superfine and activated carbon filter cartridges, extends their service cycles and prevents premature saturation of refrigerated dryer desiccant media.

Low Pressure Drop & Energy Saving

Deep-pleated glass fiber media maximizes effective filtration area. Stable low airflow resistance is maintained under 24-hour full-load continuous operation, cutting extra power consumption of air compressors and lowering overall factory air supply operating expenses.

High Dirt & Liquid Holding Capacity

Multi-gradient layered depth filtration structure stores large volumes of separated lubricating oil, condensed water and solid sludge contaminants, prolonging maintenance intervals and minimizing production downtime during filter replacement.

Impact Resistant Reinforced Support Frame

Dual plastic protective cages withstand high-speed airflow impact, avoiding filter media collapse, deformation and fiber shedding to eliminate secondary fiber contamination of clean compressed air.

Working Principle

Raw unprocessed compressed air enters the cartridge from the outer protective frame. The outer coarse fiber layer traps large solid particles, liquid water and bulky oil droplets. Minor oil mist is coalesced into heavy liquid condensate, which sinks to the filter housing bottom and drains automatically via gravity. Primarily purified compressed air flows to the secondary medium coalescing filter for further oil removal.

Application & Industries

First-stage protective pre-filter for medium-flow industrial compressed air post-processing systems, installed upstream of medium coalescing filters and refrigerated air dryers.

Widely used in general machinery manufacturing, automotive production lines, packaging printing factories, textile industrial parks, conventional industrial spraying, pneumatic tool stations, food primary processing, medium laser cutting and factory centralized compressed air supply systems.
