Spray booths & Painting chamber: IKFS Diagonal series
Pre-order
The IKFS Diagonal series comprises painting and drying booths with diagonal airflow for vehicle repair shops, commercial vehicles and large industrial products. Diagonal airflow provides the required air velocity at a lower ventilation capacity, so the booth consumes less energy and has lower operating costs. It can be installed on any level floor without underground air ducts or a specially prepared foundation, and relocated if required.

Painting and drying booths of the IKFS Diagonal series are designed for the application and drying of protective and decorative coatings on vehicles and large products made of various materials. The key feature of the series is the diagonal airflow: the required air velocity in the working zone is achieved at a lower ventilation capacity, so the booth consumes less energy and has lower operating costs.
The booth is designed in accordance with European occupational safety requirements. It provides comfortable working conditions for the operator and increases the productivity of the paint shop. It can be used with primers, paints, enamels and varnishes, including water-based coatings.
Air is supplied through the ceiling and moves diagonally towards the filter wall, through which it is removed by the exhaust unit. As a result, the booth can be installed on any level floor — without a pit, underground air ducts or a specially prepared foundation. If required, it can be dismantled and reassembled at a new site with minimal preparation work.

A programmable logic controller (PLC) and a variable-frequency drive on the exhaust fan automate the spraying, flash-off, drying and cooling modes. The control panel provides clear process visualisation.
Microclimate and Airflow
Pre-filtersSupply unit and heatingEU5 ceiling filtersWorking zone, diagonal airflowEU3 filter wall and exhaust unit
Balanced supply and exhaust ventilation keeps the booth under positive pressure, which helps prevent dust from entering. Multi-stage filtration, including EU5 ceiling filters, delivers clean supply air, while two-stage dry EU3 filtration — a cardboard labyrinth filter and a fibreglass Paint Stop filter — captures paint mist and overspray.
Depending on the configuration, the air is heated by a stainless-steel heat exchanger with a diesel or gas burner, or by an electric heater.
Operating Modes
Spraying
The air in the booth is fully renewed, preventing the build-up of explosive concentrations of flammable vapours.
Flash-off
For 10–15 minutes, the temperature and airflow remain unchanged while solvent vapours are exhausted outdoors.
Drying
Pneumatic dampers close the fresh-air supply and exhaust paths and open the recirculation path, so heated air circulates inside the booth, significantly reducing energy costs.
Cooling
The dampers reopen. The heat exchanger cools down, extending its service life, and the products cool to a safe temperature.
The temperature is set from the control panel: 16–24 °C during spraying and 20–80 °C during drying.
Construction
Enclosure — 1.5–3.0 mm steel and 60–80 mm sandwich panels, depending on the booth size.
Gates and doors — entry and exit gates and a service door for personnel.
Ventilation — centrifugal supply and exhaust ventilation units with electric motors, a pneumatically actuated damper unit, a variable-frequency drive for the exhaust unit and a manual air-pressure damper in the booth.
Filtration — ceiling structure with filter frames, an exhaust duct (filter wall) with filter frames, and a set of pre-filters, supply and exhaust filters.
Air heating — a diesel or gas burner with a four-pass stainless-steel heat exchanger, or an electric heater.
Lighting — energy-efficient LED luminaires, 4 × 18 W, around the perimeter of the working zone; ceiling and wall-mounted in larger booths.
Control panel — programmable logic controller (PLC) with automation and monitoring functions; pressure sensors monitor filter loading, duct airflow and fan operation, and a gauge shows the booth pressure.
Safety
The booth is designed in accordance with European occupational safety requirements. The equipment is approved by the State Labour Service of Ukraine for use in Ukraine.
The booth is made of non-combustible materials.
Fans and key ventilation system components are provided in an explosion-proof design.
An automatic safety interlock prevents paint or compressed air from being supplied to the spray equipment if the ventilation stops.
As an option, the booth can be equipped with a gas detection system for monitoring concentrations of flammable vapours relative to the lower explosive limit (LEL) and an automatic fire-extinguishing system.
Custom Configuration
Each booth is custom-engineered to suit production needs. Before work begins, TWEKO specialists assess the site and, together with the customer, determine the optimum configuration and coating process. As options, the booth can be supplemented with an airflow control system based on variable-frequency drives (up to 40% reduction in power consumption), 100 mm sandwich panels for better thermal insulation and outdoor installation, pneumatic painting equipment, an activated carbon air treatment unit, mobile lifting platforms for painters and a rail transfer cart.
Design documentation: up to 15 working days; manufacturing: up to 40 working days; installation and commissioning: up to 20 working days.
