• Install return air grilles or louvers as high as possible in the enclosure. Normally, one
centrally-located grille will be adequate. Avoid under sizing this grille or “short-circuiting” of air
with nearby supply registers.
• Select grilles and diffusers for low static pressure loss and proper throw and CFM rating.
• Keep the noise criteria levels of the grilles between 35 and 45 dB.
• Use anodized aluminum grilles to prevent premature corrosion.
