GMA A-core With M-frame (removable)

Grilles & Registers

The distinct "A-core" design of the GMA A-core With M-frame allows for uniform air distribution across the conditioned space at temperature differentials up to 25°F. The individually adjustable vertical fins help control the spread of discharge air as necessary.

  • A-core’s fin shape has an 85.6% free area which ensures reduced outlet velocity, pressure loss and quiet operation
  • Consists of removable aluminum frame with a 1" wide overlap margin on all sides with mitered corners
  • Features a removable core that facilitates easy installation and maintenance

    Product Application

    The GMA models from our wide range of diffusers are particularly adept at distributing air throughout an occupied zone. They are equipped with a uniquely designed A-core that allows you to adjust the vertical fins to increase throw and spread. The diffuser can provide free area of up to 85.6%, ensuring lower outlet velocity, pressure loss, and minimal noise. The GMA is an ideal fit for sidewall and sill applications.
    Product Application

    Features

    • Overlap margin with countersunk screw holes and mounting screws
    • Optional steel opposed blade damper (SOBD) available as accessory
    • Available finish options include WH - White, ML - Mill, AP - Aluminum Paint, OW - Off-White, FB - Flat Black and MP - Match Paint
    • Adjustable A-core can be field adjusted for 5° to 15° upward or downward deflection
    • The standard finish is White (WH) electrocoat in an anodic acrylic paint, baked at 315°F for 30 minutes with a pencil hardness of HB to H
    • Sizes range from 8”x4” to 48”x12”
