Designed for conference rooms, hotels, public restrooms, or any commercial spaces that require continuous ventilation, these ceiling- or in-line-mount exhaust fans feature a low-profile grille and an integral backdraft damper.
This 3-inch louver is listed with Air Movement and Control Association (AMCA) standards 540 for impact testing and 550 for high-velocity wind-driven rain.
The unit is suitable for all commonly used refrigerants — R-22, R-134a, and R-410A. It also features a self-purge function and prevents the mixing of various refrigerants.
The models come with a patented in-house designed and manufactured heat exchanger, low-profile burner, advanced controls, a built-in DHW module, common venting capability up to eight units, cascading capability up to 16 units, and built-in hardware to connect up to three zone pumps without a need for additional external controllers.
The versatility of this unit allows it to be used for a small amount of water or connected in line with a main water heater for instantaneous hot water.
