This brand is a part of GIBRALTAR INDUSTRIES and offers belt drive or direct drive units. Both of the types of units have two operating speeds. The belt drive unit has a wall switch for control while the direct drive unit uses a pull chain. The direct drive model is designed so that it can typically be installed without cutting the rafters in the attic which makes it very good for adding a whole house fan to an older home. They have a 10 year warranty on parts. airvent.com
This brand is from MARLEY ENGINEERED PRODUCTS and is only available through authorized distributors. The A24DD is a three speed direct drive whole house fan. It is a basic unit that uses a wall mounted control but it has a telescoping sleeve that allows for easy installation without changing any wood framing. They also offer three sizes of belt drive units but the warranty on the brand is not very good. marleymep.com
