Overview

The right filter housing is essential to achieving clean, dry compressed air throughout your system. Donaldson’s compressed air filter housings are engineered for long-term performance, easy servicing, and compatibility with a wide range of filtration needs — from point-of-use to centralized air treatment.

Donaldson’s compressed air housings are designed for low pressure drop, streamlined maintenance, and to integrate seamlessly into your air treatment setup. Whether you're installing a filter housing at a single machine or across an entire facility, you can count on durable construction and a flow-optimized internal layout.

Supporting flow rates from 35 to 38,400 m³/h (21 to 22,600 scfm), these housings pair with a variety of Donaldson filter elements to target everything from oil aerosols and particulates to coarse solid contamination. With options like Economizer differential pressure monitoring and zero-loss condensate drains, you can plan maintenance efficiently.
