Bypass Dampers

The DAPC is a great solution for jobs that have no room to install a by-pass or an application where you can’t use a by-pass damper. The DAPC will monitor your HVAC system static pressure and the zone damper “open” and “close” commands from the EWC Controls zone panel. When the static is too high, the DAPC will modulate any non-calling “closed” zone dampers in order to control the static pressure. The DAPC can be customized to select any desired static pressure and can pick which zone damper(s) to open when needed. The DAPC is ready to use “out-of-the-box” and can automatically discover the system’s static pressure. The balancing of static pressure into non-calling zones, or through the system is adjustable for installer convenience.

No measuring instruments are required. No weights to adjust. No springs to crank. The SBD is ACCA Manual Zr compliant. As an added benefit of the unique blade design and the smart, self-balancing feature of the SBD, there is no need to install and setup a separate bypass balancing hand damper.

Damper adjustment is easily achieved by increasing or decreasing the force applied to the bypass damper blade, until the desired static pressure is achieved.

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.
