Corrosion Resistance: Rolled steel housing and aluminum components resist oxidation in outdoor settings

systems often face pressure switch tripping or localized corrosion due to leakage

This board integrates control for both the combustion air blower (inducer) and the circulating air blower

This assembly is engineered to restore optimal ventilation

Resideo ZD24X16TZ Damper 318423-701 Corrosion Resistance: Rolled steel housingThe Resideo ZD24X16TZ is a professional grade rectangular zone damper designed for high performance residential and light commercial forced air systems. Built with an extruded aluminum frame and parallel blades, this 24x16 damper ensures low leakage and maximum structural integrity under typical static pressures. This power closed spring return open model operates as a fail safe component, remaining open during power loss to prevent equipment high
