Ultra-Zone Forced Air Zone Electronic (Modulating) By-Pass Damper, 14" Dia
The EBD (Electronic By-Pass) style are self-contained units that gives 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. All round bypass dampers are equipped with low leakage blade seals. Mounting - The Pressure Switch should be oriented so that the adjustment stem is pointing vertically up. Round bypass dampers are fabricated from 20, 22, & 24 gauge galvanized steel. Shells are furnished with one straight end and one crimped end with rolled-in stiffening beads for rigidity.
