WAI Series Architectural Wall Heater

The WAI fan-forced wall heater is designed for commercial and industrial areas requiring higher KW ratings and quick recovery. The unit provides a burst of heat in areas affected by cold drafts or wide temperature swings.

  • Efficient Operation: The fan draws air into the top of the grille and discharges warm air downward to distribute heat and keep floors warm and dry. High CFMs create air circulation within the room to provide uniform temperatures.
  • Extended Capacity: The WAI is available with one, two or three modules and ratings up to 12,000 W and 480 CFM.
