The ceiling-mounted AAF®-HermanNelson® Model AH unit ventilator averages four decibels quieter than previous models, according to the manufacturer. Other features include GentleFlo™ air moving technology; reduced fan motor speeds; and a larger coil size to increase cooling capacity, which is designed to lower the water pressure drop by 25% so that a smaller pump is required.
