Constant Load ByPass Damper
The model CLBD Bypass Damper is an easy and economical way to manage system static pressure, in a zoned HVAC system.
Damper adjustment is easily achieved by increasing or decreasing the force applied to the bypass damper blade, until the
desired static pressure is achieved. See Page 2 for details.
Due to the constant load applied to the damper blade and the unique magnetic latch, the CLBD Bypass Damper can be installed
in any position on your bypass duct-work, to manage the HVAC system’s static pressure during zoned operations.
The CLBD minimizes bypass volume, while still preventing the HVAC system static pressure from rising above the selected
Static Pressure set-point.
The CLBD is a basic, cost effective Bypass Solution for Constant Speed or Variable Speed “zoned” HVAC systems.
Note:
This drawing of the Bypass damper, Balancing Hand Damper, and Related duct work is intended to serve only as a guide. Your actual
duct work layout and components may differ. Use the graphic as a guide when planning or designing a Zone system regardless of the Equipment
type, Duct layout and Airflow configuration.
