What Is a Powder Coating Booth & Why It Matters

A powder coating booth is the core workspace where powder is sprayed onto your metal parts. It directly affects coating quality, operator safety and powder cost.

A well-designed booth should capture overspray, provide stable airflow, protect operators and make cleaning and color changes as fast as possible. At Ketu, we design the booth together with the complete line – not as a standalone box.

Clean, controlled environment for stable powder application and film build.
Balanced airflow to avoid dust, turbulence and back-ionization defects.
Efficient powder recovery to reduce powder waste and housekeeping cost.
Good lighting and ergonomics for operators or robots to access all surfaces.

We always confirm final dimensions and parameters according to your real parts and layout before production.

Integrated Into a Complete Powder Coating Line

A powder coating booth is never working alone. We design your booth together with pretreatment, drying, conveyor or racks and curing oven – so there are no hidden bottlenecks.

• Distance and flow from pretreatment / drying to the booth.
• Part spacing, hanging method and working height for operators.
• Transfer from booth to curing oven without touching the fresh powder layer.
• Safety interlocks between booth, conveyor and oven if required.

Layout Support: We provide line layout drawings showing part flow direction, operator positions and connections between pretreatment, booth and oven – so your team can visualize the complete system before installation.

Powder Coating Booth FAQ

Common questions from factory owners and engineering teams when planning a new powder coating booth.

1. What information do you need to quote a powder coating booth? →

We need your main product photos or drawings, maximum part size (L × W × H), weight, number of colors and daily color changes, target output per shift, workshop layout and local power / gas conditions. Any local environmental or safety requirements are also helpful.

2. Can one booth handle many different product sizes? →

Yes. We design the opening and working area based on your largest parts. Smaller parts can be loaded on well-designed racks or jigs. The key is to keep good access and balanced airflow around all parts.

3. How do you design for fast color change? →

We use smooth internal surfaces, rounded corners and an easy-to-clean recovery system. Powder traps are minimized and access to filters and ducts is made as simple as possible. This reduces cleaning time and helps you run more colors per day.

4. What type of powder recovery system do you recommend? →

For mixed colors and flexible production, cartridge filter systems are usually best. For high-volume single colors, we recommend cyclone + filter systems. We select the system based on your powder type, color strategy and daily volume.

5. Can your booth be integrated into my existing line? →

In many cases, yes. We can design a new booth to fit your existing conveyor, oven or pretreatment. We will study your current layout, then provide a revised layout showing how the new booth is integrated.

6. What is the typical delivery time for a powder coating booth? →

It depends on the booth size and level of customization. After we confirm the technical solution and receive the deposit, we will give a clear production schedule and expected shipping date.

7. Do you provide on-site installation and commissioning? →

Yes. For complete powder coating lines, our engineers can visit your factory to guide installation, start-up and operator training. For simpler systems, we can also provide remote support with detailed manuals and videos.

8. How do you control airflow and avoid dust problems? →

We calculate airflow and filter area based on booth size and gun quantity, then validate with experience from previous projects. Together with proper housekeeping and material handling, this helps reduce dust and coating defects.

9. What about energy consumption of the booth? →

The main energy consumption comes from the exhaust fans and filter cleaning system. We select efficient fans and can provide variable-frequency drives where appropriate, so you can balance energy usage with safety and air quality.

10. How is maintenance done on the booth and filter system? →

Filter replacement and cleaning are designed to be simple. We provide maintenance instructions and recommended intervals. Access doors and panels allow easy service of fans, filters and ducts.

11. Can you customize the booth for aluminum profiles or special parts? →

Yes. We can design long booths, special opening sizes and tailored airflow for profiles, radiators and other complex products. We can combine manual and automatic spraying where needed.

12. Why choose Ketu instead of a local general fabricator? →

Ketu focuses on powder coating lines. We design the booth together with pretreatment, oven and handling system, based on real project experience in different countries. This helps you avoid hidden bottlenecks, quality issues and unexpected operating costs in the future.
