Coalescing Filters

Part No: SI43702

Product Type: In‑line high‑precision coalescing filter element

Filtration Rating: 0.01 μm, residual oil content ≤0.01 mg/m³

Max Working Pressure: 16 bar

Operating Temperature: ‑20℃ ~ +65℃

Dimension: Φ74 mm, Length 502 mm, drop‑in bayonet mounting, Weight 1.38 kg

Filter Media: Borosilicate micro‑glass‑fiber coalescing media, double plastic support cages, rubber end sealing gaskets

Recommended Service Life: 8000 working hours or 1 year. Replace when pressure difference reaches 0.08 bar. Must be protected by upstream SI43701 particle pre‑filter.

Main Features

High‑performance borosilicate micro‑glass‑fiber coalescing media efficiently captures sub‑micron oil mist and fine solid particles for deep‑duty oil‑removal air purification.

Double‑layer reinforced plastic support cages resist high‑speed airflow impact and prevent media deformation for long‑term continuous‑duty compressor operation.

Optimized media layout delivers low initial pressure drop to reduce system energy consumption. Good resistance to condensate and aging.

Integrated rubber end seals eliminate bypass airflow and guarantee real filtration efficiency.

Installed downstream of SI43701 particle filter as secondary fine‑filtration for painting, pharmacy, food‑processing and electronic industries.

Application Industries

Screw compressor post‑treatment systems, general manufacturing, spray painting, food processing, pharmacy, electronics, mining and building‑material industries. Performs deep‑duty oil‑mist and fine‑particle removal for compressed‑air purification.

Product Summary

Secondary deep‑duty filtration removes sub‑micron oil mist and solid contaminants, delivers low‑oil clean compressed‑air for high‑demand industrial processes.
