Description
The EWC Controls CLBD-16 is a 16-inch round static pressure bypass damper engineered to maintain proper duct pressure balance in residential and light commercial HVAC zoning systems. When zone dampers close and static pressure rises in the supply duct, the CLBD-16 automatically opens to divert excess airflow back to the return side — protecting the blower, reducing noise, and extending system life.
Key Features
- 16-inch round duct configuration for high-capacity airflow applications
- Static pressure-actuated operation — no external power or controls required
- Automatic bypass action protects blower motor from over-pressurization
- Reduces system noise caused by excessive static pressure buildup
- Ideal for use in multi-zone forced-air HVAC systems
- Compatible with EWC Controls zoning panels and other major zone control systems
- Durable construction for long-lasting, low-maintenance performance
Application
The CLBD-16 is designed for installation in the supply plenum or main supply trunk, providing a passive pressure relief path whenever one or more zone dampers are in the closed position. This helps maintain consistent airflow across all zones and prevents the equipment from operating against excessive static pressure.
