Modular Air Handling Unit® (MAHU)

Modular Air Handling UnitThe MAHU line of fan coil units is a high quality, high performance, cost effective small air-handling unit. The MAHU is a highly customizable unit that brings modular specific components together in a unique operating system. The MAHU is made out of extremely high quality components that are typically reserved for commercial air handlers. For instance, the MAHU comes with a fan and a cabinet that can produce high profile static pressures in the low profile format of a traditional fan coil unit.

The MAHU has been designed for applications that demand the high quality components of an air handling unit along with a fan and cabinet that can produce high static pressures in the low profile format of a traditional fan coil unit. The technologically innovative design of the MAHU allows for a very low maintenance product that is perfectly suited for Mixed Air, 100% RA, 100% OSA, economizer applications, while meeting the most stringent engineering specifications.
