Atlas Copco WSD 53-636 CFM Compressed Air Water Separator

The Atlas Copco WSD Compressed Air Water Separator is a heavy-duty, cyclone-style separator designed to remove condensate from compressed air systems. Using a power-free, multi-stage separation process, it effectively eliminates moisture without internal filters or moving parts—providing long-lasting performance with zero maintenance.

Constructed with a G BSPP flanged connection (commonly adapted to NPT for U.S. systems), this model is rated for 232 PSI max pressure and 122°F operating temperature, making it ideal for high-demand industrial environments. Its corrosion-resistant housing and integrated manual and automatic drain valves offer reliable moisture control while minimizing air loss.

Engineered for flexibility, the WSD can be installed at any point in your compressed air network and is especially effective when paired with aftercoolers or filtration systems.
