Mainstream offers the MLR Series air handling units as an economic alternative to fully-custom air handlers.

These units offer a surprisingly wide range of customizing options, including dual fans with isolation dampers, coated coils, HEPA filtration, and energy recovery. They are ideally suited for replacement applications due to the ability to easily knock down the casing and re-assemble it inside a tight space such as an existing mechanical room.

Common options include interior lighting, stainless steel linings in the cooling coil section, and checker-plate floor liner.
