Built-Up Air Handling Unit Retrofit Components

Mainstream’s complete air handling unit system experience enables us to offer a full range of components for retrofit or repair of built-up air handling units. Our components can squeeze through the tightest openings and spaces, minimizing rigging requirements without compromising performance.

Save 40% or more over new by replacing only those AHU components necessary to improve performance, preventing costly shut-downs. Downtime is minimal, and unit rebuilds can be carried out during off-hours in phases without service disruption. Our components are designed to easily integrate with existing systems.

Expedited production cycles are available on almost all components, and in some cases, lead time can be reduced to a matter of days.
