Rectangular Static Pressure Regulating Damper
The Static Pressure Regulating Damper is a single blade barometric relief damper.
The SPRD damper blade has a counter balanced weighted arm that can be adjusted to by-pass air only when necessary, on any low pressure (less than 0.5" S.P.) zone damper system.
The SPRD is used on zoned systems when the automatic closing of various zone dampers can create an excessive increase in air pressure and velocity, through the duct system.
This increase can, in some cases overcome the static pressure rating of the fan motor and therefore reduce the volume (CFM) of air through the unit.
The SPRD will automatically open as the air pressure in the duct system increases, in order to prevent the reduction of air flow and excessive noise and velocity through the duct system.
The weight and arm can both be adjusted to allow the SPRD to open only when necessary.
It is recommended that the SPRD be located in a common duct, as far away from the air handler as possible.
Size - 20" x 10" (508mm x 254mm).
Hawaii & Alaska will be extra.
