March 27, 2006—The new ceiling-mounted AAF-HermanNelson Model AH unit ventilator from McQuay averages four decibels quieter than previous models, says the company. This is less than half the sound level of previous models and can help schools meet low noise criteria levels required in today’s classrooms. GentleFlo Air Moving Technology combined with reduced fan motor speeds provide the low sound levels.
A larger coil size increases cooling capacity by eight to ten percent over current models. This allows cooling requirements to be satisfied with a smaller unit, or with the same size unit operating at a lower fan speed for even quieter operation. The larger coil size also lowers the water pressure drop by 25%, so that a smaller pump is required, reducing both the first cost and operating cost of the unit.
