(13-14) VFD System with Powered Dampers and Pressure Transmitter - Type 3
Lev-co’s LEVEL 3 VFD system allows for “On-Demand” flow control of an exhaust fan for industrial ventilation applications.
FUNCTION:
  • The fan is first activated by an "Optional" switch attached to the hose reel or hose drop. When this switch closes the fan turns on and opens the first motorized damper.
  • Once the damper in the 1st drop opens, a digital pressure transmitter senses the pressure in the main duct downstream of the fan and allows the VFD to actively control motor speed as a function of duct (negative) pressure.
  • As more dampers are opened and closed the fan speed increases and decreases in order to provide the required flowrate at each drop. This permits constant, effective exhaust at a target duct pressure no matter how many dampers are open or closed. Flow "On Demand"
  • As each hose reel or hose drop returns to its stored position, the damper on each drop closes.
  • The fan turns off when the last operator returns the hose to its stored/recoiled position
    The following components are included in this “Level 3” VFD solution:
  • VFD (Variable Frequency Drive) IP55
  • Control Panel IP55 complete with with the following components
  • HOA Manual/Off/Auto selector switch
  • Step-Down transformer used to supply 24 volt dampers
  • ”Fan on” Pilot Light
  • Pressure Transmitter 4-20 ma
  • Pressure Gauge 1-10” WG
  • 100’ of pneumatic tubing
  • 1/8” MPT hose barb (for connection to duct)
  • Do you need a BUDGETARY estimate?
