The AAF-HermanNelson unit ventilator from this Minnesota-based company was designed to offer quieter operation, added cooling capacity, chassis strength and more. A completely redesigned air moving system greatly reduces sound levels, while a new coil design adds cooling capacity. Sectionalized front panels provide maintenance and service personnel easy access to the unit interior. Valve or face and bypass damper control are available.
