Weather-Rite air make-up unit installation and relocation
Weather-Rite air make-up units provide replacement air for facilities with paint booths, powder coating equipment, ovens, blast ventilation and other exhaust-heavy processes. Double D Mechanical plans installation, relocation and connections around unit placement, ductwork, heat, gas service, electrical service, controls and maintenance access.

Replacement Air For Process Exhaust
A make-up air unit should be coordinated with the equipment drawing air out of the building. Paint booth exhaust, oven exhaust, blast ventilation and general plant air movement can affect supply location, discharge direction and comfort around the work area.
Mounting Location And Penetrations
Unit location affects duct length, roof curbs, wall openings, service platforms, condensate considerations and access for maintenance. The placement should also account for how supply air reaches the booth or process area without creating unwanted crossflow.
Fuel, Power And Control Access
Gas piping, electrical service, disconnects, control wiring and interlocks should be routed with clear access for service. Filters, heat sections, fan compartments, dampers and control panels should remain reachable after installation.
- Identify the booths, ovens or exhaust systems served by the make-up air unit.
- Review roof, wall or platform conditions before setting equipment.
- Keep filter doors, burner access, fan panels and controls clear.
Moving A Make-Up Air System
For relocation, record duct orientation, discharge direction, curb or support details, gas connections, electrical feeders and control wiring before disconnect. The new location should be checked against exhaust equipment, utility reach and service clearance.
Frequently asked questions
What does an air make-up unit support?
It replaces air removed by exhaust systems serving booths, ovens, blast ventilation and other industrial process areas.
What site details help with planning?
Duct drawings, unit data, exhaust equipment information, roof or wall photos, gas details, electrical service and control notes are useful.
Can a Weather-Rite unit be moved?
Yes, if the receiving location can support the unit, duct connections, utilities, controls and the airflow needs of the processes it serves.
Why does discharge direction matter?
Supply air should support the process area without creating drafts that disturb coating, curing, worker comfort or exhaust capture.
