Pump Fed Fogger Zone Control Kits are used in conjunction with a PLC Vision Controller to operate Pump Fed Foggers in multiple zones. Air-activated solenoids receive a compressed air signal from the controller (sold separately) to regulate the flow of compressed air and chemical solution to the foggers. A Bleed Tank Assembly keeps the air line open momentarily to clear residual chemical solution from fogger heads to prevent dripping after the solution flow is deactivated.
