Description
The EWC Controls CLBD-14 is a 14-inch round static pressure bypass damper engineered for use in residential and light commercial HVAC zoning systems. Designed to automatically relieve excess duct static pressure, this damper helps protect your equipment and ductwork when zone dampers close off airflow — a common challenge in multi-zone forced-air systems.
How It Works
As zone dampers close in a zoning system, static pressure builds in the supply duct. The CLBD-14 opens automatically in response to that rising pressure, bypassing conditioned air back to the return side of the system. This keeps static pressure within safe operating limits, reducing strain on the air handler blower and extending equipment life.
Key Features
- 14-inch round duct connection for straightforward installation in standard round ductwork
- Passive, pressure-actuated operation — no motor or wiring required
- Helps prevent over-pressurization damage to blowers, coils, and ductwork
- Compatible with EWC Controls zoning panels and other major zoning systems
- Durable construction suited for residential and light commercial applications
- Mounts in-line between supply and return duct runs
Application
The CLBD-14 is ideal for any forced-air zoning installation where supply static pressure must be managed. It is commonly used alongside zone control panels, motorized zone dampers, and variable-speed air handlers to create a balanced, efficient, and equipment-safe zoning system.
