Description
Atlas Copco Replacement Compressed Air Filter Element (DD / PD / QD Series)
The WIRES Atlas Copco replacement compressed-air filter element is designed for the Atlas Copco DD, PD, and QD series inline compressed-air filters used downstream of Atlas Copco screw compressors. The DD (red) grade provides coarse particulate and bulk water coalescing, the PD (white/silver) grade provides general coalescing down to 0.01 mg/m³ oil, and the QD grade provides high-efficiency removal of oil aerosol and particulate. Each cartridge uses micro-glass-fiber coalescing media, color-coded polymer end caps, and molded seals that match the original housing geometry for a simple, tool-assisted change-out.
Key Features
- Direct replacement for Atlas Copco DD, PD, and QD series compressed-air filter housings.
- Color-coded end caps (red for DD, silver/white for PD, high-efficiency for QD) prevent grade mismatch.
- Multi-layer micro-glass-fiber media delivers stable coalescing efficiency across the element life.
- Bonded end caps with NBR O-rings guarantee no bypass and resistance to compressor oils.
- Low initial pressure drop (< 0.02 MPa) minimizes energy waste in the compressed-air system.

Cross Reference
These cartridges cross-reference standard Atlas Copco DD, PD, and QD replacement filter elements and are interchangeable with equivalent aftermarket coalescing filters. WIRES can match your housing model, flow rate, and required ISO 8573-1 purity class.
