For a closer look, click on the photo below (bottom left) to see the Winter 2007 installation blooper.

The possible responses are listed below, with the correct reponse in bold.

	The inlet air ductwork configuration can severely impact the performance of a fan.
	Where possible, ductwork should enter the inlet of a fan with a minimum length of straight duct.
	Having a transition into an elbow at the fan intake as shown in the photo can cause excessive noise, vibration, much lower air flow, more power consumption, and shorter fan life.
	A properly designed and installed inlet connection to a fan can save operating costs and minimize fan maintenance.
	ALL OF THE ABOVE.
