Key Product Features

Intermediate Stage Oil Mist Separation & Whole System Protection

Installed after Grade F coarse pre-filter, this element intercepts 0.1 μm submicron oil mist and tiny residual condensed water droplets that coarse filters cannot capture completely. It significantly reduces contaminant load for downstream superfine and activated carbon filter cartridges, extends their service cycle, and avoids premature oil contamination of refrigerated dryer desiccant media.

Low Pressure Drop & Energy Saving

Deep-pleated glass fiber media maximizes effective filtration area remarkably. It maintains stable low airflow resistance under 24-hour full-load continuous operation, cuts extra power consumption of air compressors and lowers overall factory air supply operating costs.

Large Dirt & Oil Holding Capacity

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

Impact-resistant Reinforced Support Frame

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

Working Principle

Compressed air pre-treated by coarse pre-filter enters the cartridge from the outer protective frame. Multi-layer gradient glass fiber captures 0.1 μm oil mist aerosol; tiny oil droplets collide continuously and coalesce into large liquid condensate, which sinks to the filter housing bottom and drains automatically by gravity. Moderately purified compressed air flows to superfine filter for further trace oil removal.

Application & Industries

Core medium coalescing filter for large-flow industrial compressed air post-processing systems, installed between coarse pre-filters and superfine filters.

Widely applied in heavy machinery manufacturing, automotive production lines, packaging printing industrial parks, textile factories, industrial spraying, large pneumatic tool stations, food primary processing, heavy-duty laser cutting and factory centralized large-flow air supply systems.
