ZoneFirst SPRD-14 Damper
The ZoneFirst SPRD-14 Damper is a 14-inch round barometric static pressure regulating damper designed for high-performance HVAC zoning. In a multi-zone system, as individual zone dampers close, duct static pressure naturally increases. This barometric relief damper utilizes a single-blade, counter-balanced weighted arm to automatically compensate for this excess pressure, preventing coil freeze-ups and high-limit trips. Specifically engineered for HVAC bypass air applications, the SPRD-14 maintains a constant volume of air (CFM) across the air handler, supporting up to 1600 CFM. The mechanical design features an adjustable arm and weight, allowing technicians to fine-tune the opening point to match the specific static pressure requirements of the system, typically rated for systems up to 0.5 in. W.C.. Built with a 22-gauge 10-inch length duct body, this pressure regulating damper ensures a reliable static pressure relief solution for residential and light commercial forced-air systems without the need for complex electronic controls.
Key Benefits for Technicians:- Automatic Static Control: Provides passive static pressure relief by responding to duct pressure increases without requiring power or wiring.
- Precise Field Calibration: The counter-balanced weighted arm is fully adjustable to ensure the blade opens at the exact set point required for your HVAC zoning system.
- System Protection: Critical for avoiding short-cycling and protecting the heat exchanger/evaporator coil from damage caused by low airflow.
- Simple In-Line Installation: Standard 14" round duct diameter with a crimped end facilitates quick integration into existing bypass ductwork.
- High CFM Capacity: Optimized to handle up to 1600 CFM, making it suitable for larger residential split systems and heat pumps.
How do I size a barometric bypass damper for a zone system?
To determine the correct size, subtract the CFM of your smallest zone from the total CFM capacity of the HVAC unit. The ZoneFirst SPRD-14 is rated for up to 1600 CFM of bypass air.
Can the SPRD-14 be installed in a vertical duct?
Yes, while typically installed in horizontal runs, this barometric damper can be used in vertical ductwork. However, the weighted arm must be carefully adjusted to account for the natural weight of the blade in a vertical orientation.
What is the maximum static pressure for the SPRD-14?
This pressure regulating damper is recommended for systems with a maximum static pressure of 0.5 in. W.C. For higher pressure requirements, a motorized bypass solution may be necessary.
