Model PS-4
|
The EBD style by-pass 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 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. |
