All About Perforated Diffusers
Shoemaker perforated diffusers are high quality diffusers that provide a 4-way air pattern. Perforated diffusers are made of steel, with 3/16" holes on 1/4" staggered centers, available with modular core or curved blade air deflection, and surface or T-Bar mount. Hinged faces allow you to adjust the optional damper as needed. Shoemaker perforated diffusers are standard Soft White but are also available in any designer color.
