Coolair Power Tube Fan

Convey and distribute air from the Power Tube Fan at one end of the ventilated or heated space, through a pressurized polyethylene tube and into the house as uniformly as possible. The Power Tube Fan is for controlled environments where a precise tempering of air is critical to production. For the necessary low velocity tempering of air, these fans and tubes are perfectly matched.
