Diffusers are used to evenly distribute air throughout the conditioned space.

Downturn plenums enable an inline make up air unit to provide down discharge air. The downturn plenum is also insulated to reduce condensation build up and noise.

Use Downturn Plenums when inline modular units need to provide down discharge air. For example, all down discharge direct fired and electric heaters with DX cooling use the downturn plenum. All down discharge indirect heaters use downturn plenums.

Bolt Together Curb
Bolt Together Curbs are constructed of G90 galvanized steel. Curbs are available for quick delivery and are assembled on the jobsite.

Intake Hoods are constructed out G90 galvanized steel. Each intake hood comes with 2″ industrial metal mesh filters and rain gutters.

Modular Mixing Box
This Modular Mixing Box has been designed so that there is easy access to either side of the housing. Over-sized doors offer plenty of room through which to clean and maintain dampers, linkage and actuators. The mixing box is designed to reduce energy cost by recirculating tempered air. The tempered air is mixed with fresh air, using the controls listed below. Building static pressure control allows the dampers to be adjusted to an infinite number of position, maintaining building static pressure. Manual potentiometers allow individuals to set the damper actuator to an infinite number of positions. Electric 2-position control is used to open or close the damper.

Screen Intake hoods are constructed out G90 galvanized steel. Each intake hood comes with intake screen and rain gutters.

Trunklines create a 10ft separation between the exhaust and the make up air inlet. This gap ensures that exhaust fumes are not mixed with the fresh make up air. Trunklines are constructed of G90 galvanized steel. Trunkline hoods come with 2″ industrial metal mesh filters and rain gutters.

The V-Bank module is designed to filter out air born particulates from make up air. The modular design enables easy handling for problem free field installations. This modular unit has oversized access door on one side of the unit which give access to the 2″ washable or throw away filters and filter tracks.
