Quincy QOCS 636 Compressed Air Oil/Water Separator

The Quincy QOCS 636 Compressed Air Oil/Water Separator is a high-capacity, gravity-based system designed to manage condensate from compressed air systems handling up to 636 CFM. Using a proven multi-stage filtration process, it reduces oil content in discharged water to an industry-leading 5 ppm, ensuring compliance with EPA and ISO 14001 environmental standards.

Condensate passes through a four-stage separation sequence: initial solid filtration in the diffuser chamber, large oil droplet removal in a polypropylene bag, gravity-based separation in the holding chamber, and final purification via an organoclay cartridge. This passive design requires no external power, making it energy-efficient and easy to install in large-scale industrial environments.

The QOCS 636 features two ¾-inch FNPT inlets and a ¾-inch outlet, with a durable construction built to withstand the demands of continuous operation. Its compact footprint (23" L x 18" W x 28" H) and 55.7 lb weight make it a service-friendly choice for larger compressed air systems. Maintenance is simplified with quick-change filters, dual service indicators, and a 4,000-hour service interval depending on load and lubricant type.
