Static Pressure Control
The EBD (Electronic By-Pass) style are self-contained
units that give you the static control mounted to the damper. It is
an "all-in-one" design that makes the installation process
much easier than most electronic by-pass dampers. The static pressure
can be adjusted in the field between 0.5" to 4" of pressure.
This is done by the turn of a set-screw. Requires 24VAC to operate.
Tubing and pitot tube are included.

Model PS-4
Model PS-4 pressure switch available separately for
use with URD and ND style dampers.
Model PRD
Model PRD pressure regulating
damper is a single blade, steel, barometric damper with a counter
balanced weighted arm. The PRD provides an economical solution
for bypassing excess air when zone dampers close. Damper adjustment
is done by adjusting the supplied weights and by offsetting
the arm.

Model PRD-RD
Model PRD-RD pressure
regulating damper is a single blade, round variation of a barometric
relief damper. This is the simplest, most economical way of
bypassing excess static pressure in multi-zone applications.
Resistance is controlled by offsetting the arm and adjusting
the weights. The arm can be inserted into either side of the
damper for added versatility.
