Overview

Plenum rated make up air unit that preheats incoming fresh air, helps maintain building pressure, and supports commercial ventilation systems with fully modulating electric heat.

The Clear Air MAU Series is a packaged all in one make up air solution designed to replace air removed by exhaust systems while reducing temperature fluctuations and improving indoor air quality. The unit preheats incoming fresh air and works with building ventilation systems to help maintain balanced building pressure. Featuring an energy efficient ECM motor, fully modulating electric heat using solid state relay technology, relay logic controls, remote duct sensing, filter housing, and plenum rated construction, the Clear Air MAU Series is suited for concealed commercial HVAC applications with horizontal or vertical installation flexibility.
