Booth Exhaust Systems for HVAC Units and Fans
Finishing HVAC cabinets, fan housings and sheet metal panels depends on booth exhaust that captures overspray or powder while fitting the building. Double D Mechanical installs, relocates and connects booth exhaust systems with attention to duct routing, fan access, discharge locations and replacement air.
Discuss your installationExhaust Capture at the Work Area
Panels, frames and housings create different spray angles and powder cloud behavior. Exhaust layout should support the booth style and keep capture consistent across work areas, filter banks and part openings.
Duct Routing Through the Facility
Duct paths may need to move around roof steel, lighting, cranes, mezzanines and existing utilities. Planning should identify practical wall or roof penetrations, support points and access to dampers or cleanout areas.
Fan Location and Discharge Planning
Fan placement affects noise, service access, structural support and the discharge path. The layout should allow maintenance around belts, motors and bearings where applicable while keeping the exhaust route as direct as conditions allow.
Replacement Air and Pressure Effects
Exhaust can pull air from doors, docks or adjacent production areas when make up air is not coordinated. Reviewing air balance helps reduce drafts and supports more stable booth operation.
Walkthrough Preparation
Have booth drawings, fan data, filter information, ceiling height, roof or wall options, utility conflicts and photos ready. Notes about current airflow problems or planned production changes are also useful.
Frequently asked questions
What affects exhaust duct size and route?
Booth requirements, fan data, duct length, turns, building structure, penetration locations and service access all influence the route.
Why coordinate exhaust with make up air?
Replacement air helps prevent the exhaust system from pulling uncontrolled air through doors, gaps or nearby process areas.
Can an existing exhaust system be reused after a booth move?
It needs to be reviewed against the new booth location, fan condition, duct route, support points and discharge path.
What should be checked around the exhaust fan?
Service clearance, electrical access, structural support, vibration concerns, weather exposure and the path to the discharge point should be checked.
