Large Paint Booth
Autocoat Large Paint Booth is designed with the Side Draft Air flow (for medium sized component) is popular because of lower initial cost & lower operating cost.
Dry Type Large Paint Booth is ideally suitable for low volume production in which component or product can be rotated with the help of EOT Crane or underground turntable. & generally open type. Dry Type Large Spray Booth is more popular with handling with EOT Crane or with floor trolley & generally Open Type is suitable for industrial products paint finish quality. Open Type Large Paint Booth is to operate, easy to maintain & economical for low volume production & ideal when Industrial paint finish quality is requirement (not like ultra quality of 4 wheeler automobile)
Autocoat Dry Type Large Paint Booth incorporates metal baffles & replaceable filters as per Autocoat 4 level filtration to exhaust paint free air in the atmosphere to full fill pollution norms. Autocoat Dry Type Large Spray Booth with improved 4 level filtration system reduces recurring filter replacement cost to amazingly low when compared with competition.
For bigger components like Rail Coach, Earth Moving machineries Dry Type or Wet Type, Truck paint booth OR Rail Coach Painting Booth can be selected as per painting consumption & type of paint required. Large Paint Booths are recommended for painting of heavy parts and large components, like wagons, chassis of vehicles, trailers, etc. In a LARGE PAINTING BOOTH In which Air flows from top to bottom or in a Cross Flow Paint Booth Air Draft is from one top corner to other end of the Paint Booth.
For bigger Products & mass production consuming large quantity of paint requiring Water Type Large Paint Booth is recommended. Paint Booth is designed with central venture Water Washing system with online Paint Sludge Removal system & Sedimentation Pit. Such paint Booths are expensive & most suitable for high volume of Paint consumption.
Autocoat Engineering is the experienced Large Spray paint booth, truck paint booth, Rail coach painting, Railway painting plant, Rail coach painting Booth Manufacturer in India since last 40 years.
FAQ
Frequently Asked Questions
What qualifies as a large paint booth?
A large paint booth typically has internal working dimensions exceeding 6 m length × 4 m width × 4 m height — large enough to accommodate buses, trucks, railway coaches, structural steel sections, helicopters, marine craft, or oversized industrial machinery. Anything beyond standard car-size booths falls into the "large" or "oversize" category.
How big is the largest Autocoat paint booth?
Autocoat has installed paint booths up to 22 m length × 5 m width × 5 m height — built for railway coach manufacturers, defence vehicle painters, and large bus body builders. There is no fixed upper limit; booth size is engineered to component dimensions, factory headroom, and material handling provisions at site.
What industries need oversize paint booths?
Oversize paint booths are needed by railway coach OEMs, bus and truck body builders, defence vehicle manufacturers, structural steel fabricators, helicopter and aircraft maintenance shops, marine craft builders, wind-turbine tower coaters, large pressure-vessel makers, and heavy equipment manufacturers like cranes, earthmovers, and railway wagons.
Can a large paint booth handle bus and railway coach painting?
Yes. Autocoat's large paint booths are specifically designed for buses, trucks, and railway coaches — featuring side-loading double doors, gantry walkways for operator access, multi-zone airflow control, integrated bake cycle, and fire-suppression sprinklers. References include leading Indian bus body builders and rolling-stock manufacturers.
How is airflow managed in a very large booth?
Very large booths use multiple intake plenums and multiple blower banks distributed along the booth length to maintain uniform airflow over the full working area. Computational airflow modelling is done during design to avoid dead zones and ensure consistent overspray capture. Multi-zone controls let operators tune flow per booth section.
Do large booths need taller ceilings?
Yes. Large paint booths require factory headroom of at least 1.5 m above the booth's external roof for ducting, exhaust runs, and lighting. Total clear height can reach 7-8 m for tall railway coach booths. Autocoat verifies factory shed height during the site survey before final booth dimensions are locked.
Can a large booth be split into multiple stations?
Yes. Long large booths are often split into 2-3 working stations with inter-station partitions or curtains — allowing simultaneous prep, primer, base coat, and topcoat in different zones, or simultaneous painting of multiple components. This dramatically improves paint shop throughput without needing multiple separate booths.
How long does a large paint booth take to install?
Large paint booth installation typically takes 4-6 weeks at site once civil work is ready — significantly longer than standard booths because of greater panel quantity, structural reinforcement, multi-blower wiring, complex ducting, and zone-by-zone commissioning. Manufacturing lead time is also longer at 8-12 weeks.
What is the cost of a large paint booth?
The cost of a large paint booth varies depending on size, type, and automation. Key factors include working dimensions, airflow zones, multi-blower configuration, bake-cycle integration, intake filtration, heating fuel, lighting count, and customisation for component handling. Contact us or send enquiry for exact cost matched to your project.
Are large paint booths exported by Autocoat?
Yes. Autocoat exports large paint booths to the Middle East, particularly UAE, Saudi Arabia, and Oman — for railway, defence, and infrastructure applications. Booths ship in CKD form via JNPT port, with our installation engineers travelling for on-site assembly, commissioning, and operator training under supervised contract terms.
