Quincy QWS Moisture Separator

Quincy QWS Mechanical Moisture Separator

Keep bulk liquid out of your compressed air system—reliably and with minimal pressure loss. The Quincy QWS Mechanical Moisture Separator uses a precision-engineered internal spinner to generate centrifugal separation, removing 99% of bulk water and liquid contaminants before they reach your downstream equipment. It’s a rugged, low-maintenance solution that protects your dryers, filters, and tools while maintaining system efficiency.

Why Choose the QWS

• Proven liquid removal: Centrifugal action efficiently eliminates large water droplets and slugs.
• Low pressure loss: Typically < 1 PSIG (around 0.8 psi), ensuring maximum efficiency and reduced energy costs.
• Set-and-forget operation: Includes a standard automatic float drain to discharge collected condensate—no manual draining required.
• Long-life construction: Backed by a 10-year aluminum housing warranty for durability and corrosion resistance.
• Flexible installation: Ideal for placement after aftercoolers, air receivers, refrigerated dryers, or at key points of use throughout your system.
• Certified performance: CRN approved and ISO 8573 compliant, meeting strict quality-air standards.

Applications

The QWS Moisture Separator is your first line of defense against water contamination. Install it upstream of coalescing filters and dryers to handle bulk liquid removal, reducing the load on downstream equipment and extending filter life. By eliminating excess moisture early, it helps prevent corrosion, contamination, and equipment wear, ensuring cleaner, more reliable compressed air.

Key Specifications

• Separation efficiency: Up to 99% of bulk liquid removal
• Flow capacity range: Models from approximately 6 to 1500 SCFM
• Working pressure: Up to 232 PSIG (varies by model)
• Pressure drop: Less than 1 PSIG
• Drain type: Automatic float drain (standard on all models)

Installation Tips

Position the QWS immediately after the aftercooler—where condensate first forms—or at other key drop points in your system. Use full-size piping and avoid sharp turns on the inlet side to maintain airflow velocity for optimal centrifugal separation.

The Bottom Line

If your air lines suffer from water buildup, the Quincy QWS Moisture Separator is the reliable, energy-efficient solution. It’s simple, durable, and built to perform, delivering cleaner, dryer air with virtually no maintenance and almost no pressure loss.
