TWEKO implemented a project for the design, manufacturing, and commissioning of a paint booth and drying chamber of the AKFS Standart series for an industrial enterprise.
The booth is integrated into the coating production area and is designed for the application of liquid coating materials by manual pneumatic spraying, followed by controlled drying of products.
A supply and exhaust ventilation system with a capacity of up to 22,000 m³/h, combined with dry multi-stage air filtration and an indirect heating system based on a diesel burner, ensures stable coating conditions, efficient removal of paint aerosol, and uniform drying of coatings at temperatures up to 80 °C.
The installation of the system enabled the customer to establish a controlled coating process and significantly improve the consistency of coating quality in production.
About the client
The project customer is a Ukrainian industrial enterprise specializing in the production of polymer and technical components for mechanical engineering, electronics, and other engineering applications.
The company combines its own manufacturing facilities with engineering development, producing components and structural elements for industrial use.
During production, many products require protective and decorative coating. Stable coating quality requires controlled painting conditions, including stable temperature, clean air supply, efficient removal of coating aerosol, and uniform drying.
Due to the specific nature of its products, the enterprise required a specialized paint booth and drying chamber capable of handling long workpieces while maintaining stable ventilation and temperature parameters and ensuring safe working conditions for operators.
Solution
To meet the customer’s production requirements, a paint booth and drying chamber of the AKFS Standart series, model AKFS-S-7, equipped with a dry air filtration system, was designed, manufactured, and commissioned.
The system was specifically adapted for processing long workpieces and provides stable conditions for the application of liquid coatings and subsequent drying in a controlled environment.
The working area of the booth measures 7000 × 4000 × 2700 mm, allowing large or long components to be coated without dimensional restrictions.
The booth enclosure is built as a panel structure made of sandwich panels with mineral wool insulation, providing effective thermal insulation and stable temperature conditions during drying.
The ventilation system operates on the principle of supply and exhaust air exchange with a capacity of up to 22,000 m³/h.
This configuration creates a uniform downward airflow in the working zone, ensuring efficient removal of paint aerosol and maintaining positive pressure of 10–30 Pa, which prevents dust from entering the booth during coating operations.
Air purification is achieved through a dry multi-stage filtration system consisting of a pre-filter, ceiling fine filters, and floor filter elements designed to capture coating particles.
The drying system uses an indirect heating heat exchanger with a diesel burner. This configuration enables stable drying temperatures of up to 80 °C while ensuring uniform heating of products in recirculation mode.
System operation is controlled via an electrical control panel equipped with a thermostat, timers, and system status indicators. Operators can adjust painting and drying modes and monitor temperature, process time, and ventilation system operation.

Design features of the booth
- Panel enclosure structure.
The booth enclosure is made of sandwich panels with mineral wool insulation approximately 60 mm thick.
The panels form a rigid enclosure that provides effective thermal insulation and stable temperature conditions during coating and drying operations. - Controlled airflow.
The supply and exhaust ventilation system with a capacity of up to 22,000 m³/h creates a stable downward airflow in the working area.
This ensures efficient removal of coating aerosol and maintains positive pressure inside the booth.
Such airflow configuration minimizes turbulence and reduces the risk of coating particles settling on the surface of workpieces. - Multi-stage dry filtration.
The air filtration system includes pre-filters, ceiling filters, and floor filter elements.
This configuration ensures effective purification of supply air and reliable capture of coating particles from the exhaust airflow. - Indirect heating system.
Air heating in drying mode is performed through an indirect heat exchanger equipped with a diesel burner.
This allows stable drying temperatures of up to 80 °C while preventing combustion products from entering the working air inside the booth. - Ease of operation.
The booth is equipped with electrically operated roller doors and service access doors.
A dedicated lighting system provides comfortable and safe working conditions for operators during coating operations.
