AAF-HermanNelson self-contained unit ventilators by McQuay International can fit into existing ventilator space in classrooms and operate on electric heat or air- and water-source heat pump configurations. A two-stage compressor reduces noise and energy usage and helps provide consistent HVAC conditions. The unit uses non-ozone-depleting R-410A refrigerant. • www.mcquay.com
