ACE # PK UM DESCRIPTION
The Static Pressure Regulating Dampers, Model
SPRD, are barometric relief dampers used to by-pass
excess air pressure on zoned systems. The SPRDs
automatically respond to the air pressure in duct as
the various zone dampers open and close. As zone
dampers close off air to a number of zones, the
supply air pressure in the duct system will increase.
This increase in air pressure can increase the noise
level and reduce the flow of conditioned air through
the HVAC Unit. Using the SPRD solves this by
automatically compensating for the excess air
pressure by opening on the increased pressure and
relieving the excess air. The SPRD helps maintain a
constant air pressure in the duct system. This
reduces noise that is caused by high air pressures
and velocities, as well as maintains a constant
volume of air (CFM) through the duct system.
Maintaining a constant volume of air through the
HVAC System keeps the efficiency of the system at
its maximum.
