The air blower inflation kit uses a blower fan to push air between two layers of greenhouse plastic. This improves insulation efficiency and reduces condensation inside of the greenhouse. We don't recommend using this kit with our external frame blackout kits but functions great with internal frames and standard greenhouses. 110VAC, 0.42 amps.
Includes 60 cm blower, exhaust air deflector, and mounting bracket, 48" inlet air hose, inlet damper/air regulator
