Round Duct Bypass
The ZECV 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.
  • Terminal unit retrofit applications
  • Limits static pressure in duct systems feeding VAV devices
  • Bypass or discharge pressure control
  • Flow ranges to 4,000 cfm
  • Inlet sizes: 8”, 10”, 12”, 14”
