Atlas Copco DD180+ Compressed Air Filter

The Atlas Copco DD180+ is a coalescing compressed air filter in the DD series, designed to remove bulk liquid water, bulk oil aerosols, and solid particulates to deliver ISO 8573-1 Class 1 for oil content (≤0.01 mg/m³) and Class 3 for solid particles (≤5 μm). Handling flow rates up to 180 m³/h at 7 bar(e), the DD180+ fills the mid-range capacity bracket as a dedicated pre-dryer oil-water separator and coalescing filter for compressor outlet treatment, instrument air headers, and point-of-use filter stations. Its design integrates seamlessly into Atlas Copco compressed air treatment trains — typically positioned after the compressor and before refrigerant or adsorption dryers, or as a standalone quality upgrade on existing compressed air systems.

The DD+ series uses Atlas Copco's Optimizer+ filter element technology — a multi-layer borosilicate glass fibre element with a PTFE outer wrap that provides low differential pressure drop (typically 0.02 bar at rated flow) while achieving high coalescing efficiency. The low pressure drop directly translates into compressor energy savings — every 0.1 bar reduction in system pressure drop saves approximately 0.5–0.7% of compressor energy. The DD180+'s element has a rated service life of 4000 hours and is easily changed without tools through the quick-release element retainer. An integral differential pressure indicator confirms element condition without requiring a separate gauge or transmitter.

In Saudi Arabia, Atlas Copco DD series filters are standard components in ARAMCO-specified compressed air treatment packages, where instrument air quality must comply with SAES-J-002 requirements for oil, particulate, and moisture content. SABIC project engineers routinely include DD filters in the instrument air treatment train for all new process plant utility air packages across Jubail and Yanbu. The DD180+ is also widely used in compressed air quality upgrade projects at existing Saudi industrial facilities, where point-of-use filter skids retrofitted between the compressor room and the instrument air header bring legacy systems up to current air quality standards without replacing the compressors themselves.

Razz Middle East carries DD180+ filter housings and Optimizer+ elements in local Saudi stock, with same-day availability for most standard configurations.
