Shop Zone Dampers

Temperature inconsistencies between floors and rooms frustrate building occupants and waste energy. Zone dampers solve this challenge by dividing ductwork into independently controlled sections that respond to individual thermostat calls. These motorized devices open and close within your HVAC distribution system to direct heated or cooled air precisely where comfort demands it.

Blackhawk Supply carries zone dampers for HVAC installations ranging from two-zone residential retrofits to multizone commercial projects requiring sophisticated climate management.
