Wet Spray Booths and Dry Filtration According to Your Needs

The application process in a painting system varies depending on the capacity requirements, item type and size and painting used.

Moldow has the right type of spray booth for all kinds of painting jobs. Besides capacity, we have also taken the environment, energy consumption and safety into consideration. In Moldow painting lines, two types of spray paint booths are used: either with wet filtration or dry filtration.

Wet filtration i.e. water walls are used widely in automated painting lines where efficient

Dry filtration booths and walls are used for manual painting processes or in large painting halls, as e.g. when painting wind turbine towers.

The Moldow “No-Pump” wet filtration booths perform market-leading overspray separation of more than 99% in a wide range of both solvent and water based painting processes.

The combination of strong air management and the water-sprinkled spray walls ensure that all the overspray is caught so the operators can work safely.

The air, including the overspray, is extracted from the lower part of the booth, where the mix of air and overspray is absorbed by the water when meeting the water surface. To achieve the unrivalled collection of overspray in a Moldow spray booth, the absorption of overspray is intensified by the powerful water cyclone inside the washing tower. Inside the washing tower, the water with the bound overspray is separated through a labyrinth of deflectors, separating the water from the air allowing the air to escape through the extraction system.

The paint-filled water from the washing tower is led to the floor reservoir where coagulants are added. By adding coagulants, the paint particles are released from the water and transformed into non-sticky flocculants.


The Moldow spray booths can be supplied as Heavy Duty (HD) types upon request.

The HD system provides excellent maintenance and service access behind the booth during operation. The HD system is thus an advantage when the system capacity is high, or when minimal off-time for service and maintenance is required.


Moldow’s spray booth with dry filtration is an economically attractive solution for wet paint.

Spray booths and walls with dry filtration can with its many standard sizes be designed very user-friendly with a front opening of e.g. 3300 x 1950 mm and the easily replaceable filter media.

The Moldow dry filtration booths and walls are equipped with Andrea® filters – the most efficient dry filters on the market.

The correct depth, approved light fittings and an efficient industrial fan ensure optimal working conditions for the operator and create ideal conditions for a high finish. Moldow supplies special dimensions if required. 


The spray booths can be delivered complete with extraction duct, extraction fans, light fixtures and Andreae® filters.

Filter walls are used when arranging spray painting rooms where the work cannot be performed in booths or cabinets.
