Booth Exhaust Systems for Ship Blocks
Ship blocks and hull sections can create large coating areas with deep corners, frames and surfaces that influence overspray movement. Double D Mechanical installs, relocates and services booth exhaust systems and the duct, fan, stack and utility connections that support marine finishing operations.
Discuss your installationCapture Across Complex Hull Geometry
Overspray capture should account for broad plate, curved surfaces, stiffeners and pockets where air can slow or change direction. Exhaust placement and filter access should be reviewed around the way the workpiece is supported and painted.
Fans, Ductwork and Stack Placement
Exhaust fans and duct routes must fit the building as well as the booth. Roof penetrations, wall openings, structural steel, crane travel and exterior stack locations should be coordinated before fabrication and installation work begins.
Air Balance With Supply Equipment
Exhaust volume has to be matched with replacement air so the booth and surrounding plant remain manageable. Air make up units, door positions and booth operating modes should be reviewed together rather than as separate pieces.
Filter Service and Cleaning Clearance
Large marine coating areas need maintenance access that remains practical after the booth is in production. Filter banks, fan bearings, access doors, dampers and cleanout points should be reachable without blocking part movement.
Site Review Preparation
The first walkthrough is more productive when the exhaust path and production flow are visible on paper or in photos.
- Booth location and proposed exhaust route
- Roof or wall penetration constraints
- Fan, filter and stack information if existing
- Largest workpiece and handling method
Frequently asked questions
What makes exhaust planning difficult for hull sections?
Large surfaces, irregular structure and the scale of the booth can create airflow patterns that need careful review for capture and service access.
How are exhaust ducts routed in marine fabrication buildings?
Routes are planned around structure, cranes, doors, other equipment, service access and available roof or wall openings.
Why coordinate exhaust with make up air?
The exhaust system removes air from the booth, so replacement air is needed to support airflow, pressure balance and working conditions.
Can an exhaust system be serviced or modified after installation?
Yes, but access to fans, filters, dampers, cleanouts and controls should be considered early so service work does not disrupt production more than necessary.
