Waterfall Type Wet Paint Booths

ACROTECH Waterfall Type Wet Paint Booths are professional liquid painting systems that capture overspray through a water curtain system, delivering outstanding surface quality results and excellent working environment ergonomics.

Waterfall System Operating Principle

In ACROTECH Waterfall Type Wet Paint Booths, overspray that does not adhere to the workpiece surface is captured by a specially designed waterfall and prevented from being released into the environment. The water curtain system effectively captures paint particles and prevents them from being emitted into the atmosphere. This system is the most preferred solution especially in the wood furniture and automotive industries where visual quality expectations are extremely high.

The waterfall operates in dual stages and captures liquid paint particles suspended in the exhaust air. The first stage captures large particles, while the second stage captures finer particles. This reduces paint emissions to the atmosphere to virtually zero, ensuring full compliance with environmental regulations.

Positive Pressure Control and Surface Quality

Paint application is carried out inside an enclosed booth under positive pressure. This feature guarantees that the final coat surface quality meets expected levels, particularly in glossy lacquer applications. Filtered air at positive pressure prevents foreign particles from adhering to the painted surface. Dust, pollen, insects, and other contaminants are prevented from entering the painting area.

ACROTECH guarantees the most critical application parameters in waterfall liquid paint booths: positive pressure, exhaust air filtration, clean air distribution and temperature control, homogeneous air velocity, and ventilation. All these parameters are continuously monitored and optimized via a PLC control system.

Technical Features and Advantages

Dual-Stage Waterfall System: Provides maximum overspray capture efficiency. The first stage achieves 85% efficiency, the second stage 95%, delivering a total filtration performance of 99.75%. Virtually zero emissions are released into the atmosphere.

Easy Maintenance and Cleaning: The water curtain system can be easily cleaned at regular intervals. Cost and production losses during maintenance are minimized. Draining and cleaning the waterfall reservoir is simple and fast. No filter replacement is required, which reduces operating costs.

Superior Surface Quality: Enclosed booth application under positive pressure delivers outstanding results, especially in glossy lacquer and high-gloss applications. Orange peel, dust, and other defects on the surface are minimized. Mirror-like surface quality is achieved.

Operator Health and Safety: Thanks to the enclosed system and positive pressure, operator exposure to paint fumes is minimized. The working environment is fully compliant with occupational safety standards. The exhaust system continuously cleans the air inside the booth.

Application Areas and Industries

Wood Furniture Industry: Waterfall type booths are the primary choice for glossy lacquer, varnish, and polyester applications in wood furniture manufacturing. They deliver excellent results on doors, cabinets, tables, chairs, and decorative wood products, with outstanding performance particularly on MDF and laminated parts.

Automotive Industry: Used for vehicle body panels, bumpers, hoods, trunk lids, and interior trim part painting. Ideal for automotive supplier applications requiring high visual quality. Preferred for custom vehicle painting and restoration work.

Metal and Plastic Part Painting: Used for white goods panels, office furniture metal components, decorative metal objects, and plastic part painting. Suitable for all applications requiring high quality and smooth surface finish.
