Airtec's MV Ceiling Diffuser Offers up to 80% Installation Savings for Contractors

One-piece, U.S. factory-assembled diffuser/damper/collar combination won't leak and is field-installed in 72 seconds or less. Airtec Products Corp., Fall River, Mass., a leading manufacturer and importer of HVAC/R products offers the MV Ceiling Diffuser Series, a one-piece, diffuser/ damper/collar/box combination manufactured and assembled in the USA that's the HVAC industry's quickest installing diffuser for residential or commercial applications. The MV Series diffusers are constructed of scratch/heat-resistant, rust-proof white engineered polymer in two sizes: 8x8 and 6x6-inch-square or 8 and 6-inch-diameter round styles. Square faceplates are available in conventional two, three or four-way directional louvers, return grille styles or black and white choices of faux cast iron antique grille designs. The all-in-one ceiling diffuser installs in 72 seconds or less thus saving up to 80-percent field installation time versus up to four separate field-assembled pieces to do the same job. Unlike the leak potential of field-assembled diffusers, the MV Series' seamless, airtight sealed construction is designed to distribute air with virtually no leakage. This makes the MV Series a perfect value-engineering choice for both new construction and retrofit air distribution projects. The MV Series offers a unique three-stepped collar design that easily adapts to 6, 7, or 8-inch or 4, 5 or 6-inch round ducts for the 8-inch and 6-inch-diffusers, respectively. The included tight-sealing, 90-degree butterfly damper features rubber gasketed construction and an anti-binding, corrosion-resistant mechanism that is adjustable by screwdriver or by hand with a decorative knob. Other features include:

  • engineered polymer material has built-in color that makes scratches easy to rub out, doesn't attract condensation, and can be painted to match interior decor;
  • Installation requires simply cutting the access hole, attaching the duct and rotating four mounting clips into position via a screwdriver to tighten and secure the diffuser assembly to the ceiling;
  • MV Series includes many flange and side entry box connection accessories for unconventional applications; For more information on Fortress please call 1-800-3AIRTEC, (1-800-324-7832) email, or visit About Airtec: Airtec manufacturers air diffusion, condensate management and lineset ducting products; and imports mini-split accessories, equipment support systems and other HVAC products.
