General Information:
Price variable volume retrofit units are designed for installation into rectangular ductwork, easily converting constant volume systems into variable air volume. This conversion is simply accomplished by cutting a rectangular hole in the existing ductwork and sliding in the retrofit unit. The unit is fastened to the duct with a heavy gauge mounting plate and steel mounting angles. The retrofit unit provides pressure independent variable air volume control.

- Rugged 22 gauge zinc-coated steel housing.
- 20 gauge zinc-coated steel damper rigidly fastened to a 1/2 in. round zinc plated solid shaft which rotates in durable polyethylene bearings. Damper position is identified by a mark on the end of the damper shaft.
- Heavy 20 gauge zinc-coated steel control panel fastens to 20 gauge zinc-coated steel mounting angles which are used to secure the unit to the rectangular duct.
- The edges of the measuring station are gasketed to provide a tight seal.
- Multipoint flow sensor averages and amplifies velocity for accurate control.
- Available with pneumatic, electronic or direct digital controls.
- SP300 multipoint flow sensor designed to maintain control accuracy indepen-dent of field installation conditions.
- Gauge taps for flow measurement and balancing supplied with factory mounted pneumatic controls (optional for digital controls by others).
