Atlas Copco WSD 75+ Compressed Air Water Separator

The Atlas Copco WSD 75+ Compressed Air Water Separator is a compact, cyclone-based solution engineered to remove condensed water from compressed air systems operating at flow rates between 54–159 CFM. Designed with no moving parts, the WSD 75+ offers a completely maintenance-free operation and ensures long-term protection for your downstream equipment.

Constructed with a G 1" BSPP connection (typically adapted to 1" NPT for U.S. systems), this unit is rated for pressures up to 232 PSI (16 bar) and can be installed at any point in your air network. It features both manual and automatic condensate drains, including an intelligent drain system that uses liquid level sensors to discharge only when necessary—minimizing air loss and maximizing energy efficiency.

With a lightweight, corrosion-proof design, the WSD 75+ is ideal for industrial and commercial compressed air systems where reliability and water removal efficiency are essential.
