Io Hvac Controls EZ-BD-14 Pressure Relief Damper 14 in

Product Description

The IO HVAC CONTROLS EZ-BD-14 is an adjustable pressure relief damper designed to regulate static pressure in forced-air duct systems. When system pressure exceeds the set threshold, the damper opens to relieve excess pressure and protect downstream components. It installs in bypass or return-air applications where balanced airflow and pressure control are required. The unit measures 16.25 inches wide by 14.25 inches tall by 16.25 inches deep and weighs 9 pounds. HVAC technicians working on residential and light-commercial zoned systems are the primary installers of this product.

This damper is suited for forced-air systems where static pressure buildup is a concern, particularly in zoned HVAC installations. When zone dampers close and system pressure rises, a properly set pressure relief damper prevents blower strain and duct stress. It is appropriate for use in bypass duct runs or as a return-path relief device in both new construction and retrofit applications.

Key Features

• Adjustable pressure relief setting allows field calibration to match system design requirements
• 14-inch nominal size fits standard duct openings in residential and light-commercial systems
• Overall footprint of 16.25 x 14.25 x 16.25 inches for straightforward rough-in planning
• At 9 pounds, the unit is manageable for single-technician installation in tight mechanical spaces
• Passive operation with no electrical connection required for basic pressure relief function

Compatibility

Designed as an OEM-style pressure relief damper for use in forced-air zoning systems requiring static pressure bypass or relief in 14-inch duct applications.

Installation Notes

Installation is typically performed by a licensed HVAC technician familiar with forced-air zoning system design. Power down the air handler or furnace at the disconnect before beginning duct work. The damper should be mounted per the manufacturer orientation markings to ensure correct pressure-relief operation. Duct connections must be properly sealed to prevent air leakage after installation.
