Overview

Donaldson’s compressed air filter elements combine advanced media technologies with efficient design - helping extend equipment life and support clean, consistent airflow. Whether you're using a coalescing filter and particulate filter in one unit, or selecting a dedicated inline air compressor filter, each element is built for high contaminant retention, low pressure drop, and system flexibility.

Our UltraPleat™ pleated media features a structure of coated high-tech fibers, delivering exceptional fine particulate filtration, oil mist removal, and liquid/gas coalescence. This makes them ideal for applications involving the removal of both liquid contaminants (oil mist, water) and solid particles (dust, dirt, rust).

We offer elements compatible with Donaldson DF, SG, HD, EG, P-EG, and PG-EG housings - along with competitive fit replacements. Many series are available in HTNX (high temperature) and HTCR (corrosive-resistant) configurations for rugged environments. Whether you need a first stage filter, a dual-stage filtration system, or high-efficiency oil removal filters, Donaldson has you covered.
