Greenheck Fan Corp.
Greenheck offers air distribution products for ventilation systems including grilles, registers, diffusers (GRDs) and air terminal units (ATUs). The line has models of supply and exhaust grilles and registers, ceiling diffusers, linear diffusers and grilles, plenum slot diffusers, and variable air volume (VAV) diffusers. Air terminal units include single duct, dual duct, constant volume, variable volume, and retrofit models. Air distribution products are also offered for specialty applications such as displacement ventilation for spaces with ceiling heights of 9 feet or greater, allowing more heated waste air to be removed. Stainless steel GRDs are available for applications requiring corrosion resistance and durability. A line of fire-rated air distribution products is designed for use in 3-hour fire-rated exposed grid suspended ceilings.
Rite-Hite Corp.
Rite-Hite’s Revolution LT high volume, low speed (HVLS) fans pull air from above and pushes it down to floors in a conical shape, spreading to 85 feet from the center. The cone shape allows the fan to cover as much as 22,000 square feet without a dead air spot in the center. The four-blade fans are available in 8- to 24-foot diameters. Users can operate Revolution LT Fans with a 4-inch touchscreen controller with an on/off button, speed adjustment setting, and forward/reverse settings.
