The SmartZone™ ‐series low pressure modulating damper was developed for precise control of supply air in the HVAC duct system. The solid PVC shaft eliminates external condensation and damage to the actuator drive hub. The damper actuator is designed for years of care‐free operation. The modulating open and close design guaran‐ tees precise control of supply air into each zone. Poron® rubber blade edges provides a positive seal for the blade. Our gasketed damper blade is designed to compensate when installation conditions are not exact and the damper is not perfectly round. Long‐life nylon bushings insure a quiet, low friction operation of the damper. Heavy‐duty galvanized steel spiral cylinder provides strength to keep the damper round. One crimped end and one straight end allows for flexible installation. Works with Carrier Infinity™ and Bryant Evolution™ zoning systems.
