A small powder coating booth is the easiest solutions for powder coating applications when you don’t have many colors and you don’t need to change colors often. Our manual powder coating spray booths are designed and manufactured either from galvanized sheets or mild steel sheets which are then painted.
There is an inside space for the painter to hang his parts and paint with his powder coating gun, while filters suck and clean the air in the medium and blow off the paint gathered on the filters once in a while.
Manual powder coating booths can be made starting from 1 filter and 2,3,4,5,6 and 8 filters maximum. We use 32x60cm cellulose powder coating filters in our booths. There is an electrical board, to control the blow-off valves to clean the filters and lights inside for the operator to see and check the painting quality
Filtration is achieved by using cartridge filters in an open compartment. The filtered clean air (now devoid of powder particles) then passes through a sealed plenum chamber and via the centrifugal extraction fan back into the factory atmosphere. The system avoids any explosion risk that may be caused by passing powder-laden unfiltered air into a sealed chamber.
Sound Level Due to the level of airflow required the noise level determines that ear defenders are required.

- A timer system allows operators to set and control the dwell time, ensuring that workpieces remain in the oven for the required duration for complete curing.
- Monitoring and Safety Systems:
- Monitoring systems may be incorporated to track and display temperature, conveyor speed, and other critical parameters.
- Safety features such as emergency stop buttons and temperature alarms enhance the overall safety of the curing process.
- Compliance with Regulations:
- The curing oven design and operation should comply with local safety and environmental regulations associated with powder coating operations.
- Accessibility for Maintenance:
- Design features that facilitate easy access for maintenance tasks, such as cleaning or replacing heating elements and inspecting insulation.
- Heat Recovery Systems:
- In some cases, heat recovery systems may be implemented to capture and reuse excess heat, improving overall energy efficiency.
Properly designed and maintained curing ovens are crucial for achieving high-quality powder coating finishes. They play a significant role in ensuring the durability, adhesion, and appearance of the cured powder coating on the workpieces. Regular maintenance and adherence to safety protocols contribute to the longevity and effectiveness of the curing oven.
