Ewc Controls ECLBD-14 Constant Load Bypass Damper 14 in

Product Description

The EWC CONTROLS ECLBD-14 is a 14-inch round, pressure-regulating constant load bypass damper rated for up to 1800 CFM. It is designed for use in forced-air HVAC zoning systems where maintaining consistent static pressure is critical to system performance and equipment longevity. A built-in setscrew allows the installer to dial in the desired static pressure setpoint without guesswork or external gauges. The adjustment range runs from 0.3 inches WC to 0.8 inches WC. A static pressure indicator window confirms the current setpoint, and a blade indicator viewing window shows blade position during live system operation. HVAC technicians and zoning installers will find this damper straightforward to commission on the first visit.

The ECLBD-14 is suited for residential and light commercial forced-air zoning applications where a bypass damper is needed to manage excess static pressure when zone dampers close. Its round 14-inch profile fits standard round ductwork. The damper can be installed at any angle and in any orientation, which simplifies placement in tight mechanical rooms or unconventional duct runs. This flexibility reduces labor time during installation and eliminates the need to plan duct routing around fixed-orientation hardware. It is typically installed between the supply plenum and the return side of the system as part of a complete zoning assembly.

Key Features

• Setscrew-adjustable static pressure from 0.3 to 0.8 inches WC eliminates manual bypass guesswork
• Static pressure indicator window displays current setpoint for quick field verification
• Blade indicator viewing window shows live blade position during system operation
• Installs at any angle and any orientation for maximum placement flexibility
• Rated for up to 1800 CFM airflow capacity
• Round 14-inch form factor fits standard round duct connections

Compatibility

Designed as an OEM-style pressure-regulating bypass damper for forced-air residential and light commercial HVAC zoning systems using 14-inch round ductwork.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with forced-air zoning systems. Power down the air handler or furnace at the disconnect before making any duct connections or wiring the damper into the zoning control panel. Use standard sheet metal screws and foil tape to secure and seal the duct connections. After installation, verify the static pressure setpoint through the indicator window before returning the system to service.
