Big Size Spray Booth for Vehicle Bodies & Large Components

Category: Products / Spray Booth   |   Industry: Automotive, EV, tractor, machinery cabs-dated Sep 18th,2026

Editorial summary  This release presents CoatTech's big-size spray booth for painting oversized parts such as electric vehicle bodies, tractor cabs and large welded fabrications. It combines a full-width paint grid floor, full-body containment sheeting, high-output ceiling lighting and a multi-station layout so several operators can work one long part at the same time.

CoatTech big-size spray booth: two operators painting an EV body shell on a mobile dolly over a full paint-grid floor

  01    What the picture shows

Vehicle body shell on a mobile dolly — a small electric vehicle body is positioned on a wheeled steel dolly running on floor rails, so a long part can be moved and turned inside the booth

Two painters working one part — one operator sprays standing up, the other works crouched at bumper level — the booth width supports multi-position, multi-operator painting

Full paint-grid floor — perforated metal grating across the whole booth floor collects overspray and allows air to pass through uniformly

Full-body containment sheeting — both side walls and the ceiling are lined with protective film, keeping overspray off the structure and making colour changes easier to manage

High-output ceiling lighting — rows of lamps in the ceiling grid give shadow-free illumination for checking coverage and finish quality

Ceiling plenum and ducting — the painted steel ceiling with access panels and flexible duct connections shows a filtered, balanced air supply system

  02    Key features

Oversized cabin — extra length, width and door height for vehicle shells, cabs, hoods, doors and large fabrications

Multi-operator layout — wide enough for two or more painters to coat one long part from different sides at the same time

Paint-grid floor on rails — grating panels on a rail system guide the dolly and support the part while allowing overspray and air to pass through

Full interior containment — wall and ceiling sheeting protects the booth envelope during messy colour work and is simple to replace

Balanced airflow — filtered ceiling supply and lower-level extraction control overspray and keep the operator breathing zone cleaner

Bright, even lighting — ceiling lamps are arranged for uniform illumination with minimal shadows on curved panels

Heavy-duty structure — steel frame, panel walls and ceiling plenum built for daily production use

  03    Technical data

* Internal dimensions, airflow volume, heating capacity and filtration stages are confirmed during layout engineering and depend on part size, coating type and daily output.

  04    Applications and benefits

This booth suits manufacturers of electric vehicles, low-speed vehicles, tractors, agricultural machinery, construction equipment, buses and large metal fabrications. Benefits include the ability to paint an entire body shell in one station, shorter handling time, easier multi-side coating, better visibility for quality checks, and a cleaner, more controlled working environment.

 Frequently Asked Questions

Q: What is a big size spray booth?  A: An oversized paint booth with enlarged length, width and door height, built to coat vehicle shells, cabs and other large components that do not fit a standard booth.

Q: Can it paint an entire EV body shell?  A: Yes — the cabin, door height and floor system are designed around the part, and a mobile dolly lets the body be positioned and turned inside the booth.

Q: Can two painters work at the same time?  A: The wide cabin supports several operators coating one long part from different sides, which shortens cycle time on large shells.

Q: What kind of floor does it have?  A: A paint-grid / grating floor on rails. It supports the part dolly, lets overspray and air pass through, and is easier to clean than a solid floor.

Q: Is the airflow downdraft?  A: The layout uses full-ceiling filtered supply with lower-level extraction. Final airflow type and volume are confirmed during layout engineering.

Q: Can it be equipped with a drying system?  A: Yes — warm-air heating or infrared modules can be added for flash-off and curing, depending on the coating process.
