EWC Controls CLBD-16 Damper

The EWC Controls CLBD-16 is a professional-grade 16-inch round barometric bypass damper designed to manage system static pressure in multi-zone HVAC applications. As the modern direct replacement for PRD-RD-16, the CLBD-16 utilizes a constant load design and a unique magnetic latch, eliminating the cumbersome weights associated with legacy bypass solutions. This 16" round static pressure damper is ACCA Manual Zr compliant, providing a precise, mechanical method to bleed off excess air when individual zone dampers close, preventing coil freeze-ups and excessive duct noise. The unit features an easy-to-read static pressure indicator window and a blade position viewer, allowing for set-screw adjustments from 0.3" WC to 0.8" WC. Its versatile construction ensures reliable performance in horizontal, vertical, or angled duct orientations, making it a universal fit for high-capacity zoning system bypass runs up to 2200 CFM.

• Universal Mounting: The magnetic latch and constant load spring allow for installation at any angle, providing maximum flexibility in tight mechanical rooms.
• Precise Pressure Calibration: Integrated static pressure set-point indicator allows for immediate verification of system bypass levels without a manometer.
• Direct Replacement Logic: Specifically engineered to supersede the EWC PRD-RD-16, ensuring seamless integration into existing Ultra-Zone ductwork.
• High Airflow Capacity: Rated for up to 2200 CFM, accommodating large residential and light commercial constant speed or variable speed systems.
• Durable Construction: Built with 13-gauge aluminum for long-term structural integrity within the bypass duct.

Common Questions How do I adjust the static pressure setting on the CLBD-16? Adjustment is handled via a single setscrew located on the side of the housing. Turning the setscrew increases or decreases the force on the internal spring, which is reflected in the static pressure indicator window. Can this replace older weighted-arm dampers? Yes, the CLBD-16 is the technical successor to the PRD-RD-16 and other 16-inch weighted barometric dampers, offering a more stable and easier-to-calibrate constant load operation. Is this damper suitable for vertical airflow? Yes. Unlike traditional weighted dampers that rely on gravity, the CLBD-16 Round Bypass Damper uses a magnetic latch and calibrated spring, permitting 360-degree installation orientation.
