Abstract
An induction diffuser (100), radial flow diffuser (130), linear diffuser (150) and supply or return grille (170) use a fabric face (102, 132, 152, 172) to form the exposed portion thereof. The fabric face is preferably made of fiberglass or Kevlar coated with teflon. The use of the fabric face increases reflectivity of incident light, reduces sound levels, provides a durable and easily cleanable surface and provides other significant benefits.
