UVC1 and UVC2—
Galvanized Steel Damper
The
UVC1 parallel blade damper is recommended for constant pressure drop applications
such as mixing air, multi-zone, face and bypass as well as normal open/closed
applications. The UVC2 opposed blade damper is recommended for varying
pressure drop applications such as volume control.
UVC1
and UVC2 dampers are designed for "in-duct" mounting. The single-thickness,
roll-formed blades and roll-formed frame are capable of withstanding differential
pressures of 4 in. wg and 3000 fpm at its maximum panel width (for higher
pressures and velocities, contact your local McGill AirFlow sales location).
