Just replace the existing screen and small 12-volt fan with the Vortex fan kit to turn your roof vent into a powerful ventilation system. This kit upgrades your present powered roof vents into a powerful high velocity air movement system in just minutes. The Vortex I is a single speed fan.
Installation is easy with only a Phillips head screwdriver! Just take out the current screen, garnish and motor and replace it with the Vortex system. Non-powered vents can be converted with additional wiring.
Upgrade your old, inefficient powered vent easily without replacing the entire vent or disturbing the rooftop seal.
