ZQCV
Rectangular Duct Bypass
The ZQCV is an excellent unit for pressure control either in a new system or retrofitting an existing system. It particularly performs well in systems where constant volume supply fans are used with variable volume control. It has a tight close-off damper and leakage is less than 2% of nominal cfm at 6-inch Ps wg.
