Complete Air Handling Systems, Modules And Components

The goal of Mainstream is to reduce the costs and extensive lead times associated with the supply of custom air handling units. To this end, we have developed special software tools that simplify technical and business processes, reduce human error, and guarantee a superior solution. For complete systems, Mainstream can offer consistently short lead times for both standard (10 weeks) and expedited (4 weeks) if required.

Perhaps an even greater challenge is reducing the frustration level connected with retrofit and replacement of air handling units, particularly in tight spaces. Mainstream can design air handling units to be built in small pieces and fit through the smallest openings for final assembly.
