Bellows

A bellows is a device for delivering pressured air in a controlled quantity to a controlled location. At its most simple terms, a bellows is a container which is deformable in such a way as to alter its volume, and has an outlet or outlets where one wishes to blow air. A bellows differs from a fan in that it exerts much greater control in where it delivers the air...taken from Wikipedia.

In industrial applications bellows are made with a variety of materials such as Neoprene, Silicone, SBR, Nitrile (oil resistant), hypolon, EPDM (heat resistant), and Teflon. Materials could vary from fabric reinforcements to wire inserted for strength and support. Bi-State Rubber, Inc. is one company who offers custom bellows fabrication.

Sometimes bellows are fabricated with a zipper for quick change out situations.
