The Windshear II like all dryers in the Windshear series is designed as a stand alone drying system. This dryer utilizes two 30hp magnum blowers, plenum and three Prot-Duck air delivery bags. The magnum blower assembly is manufactured from powder coated steel while the plenum is made from aircraft grade aluminum. All the bags are produced from durable Proto-Duck material designed to direct air around the vehicle as it passes under the equipment arch. The drying quality in the Windshear dryers far surpasses any comparable horsepower dryer in its class.
