Water Curtain Swirl Spray Booth High Efficiency Low Maintenance Anti Clogging

The water curtain swirl spray booth combines a full-width water curtain with a high-velocity cyclonic swirl chamber to capture paint overspray, dust, and a portion of VOCs at over 97% efficiency. As the exhaust fan draws paint-laden air into the booth, the falling water curtain instantly traps large sticky droplets. The remaining fine mist enters a swirl chamber where intense centrifugal mixing forces intimate contact between air and water, separating microscopic paint particles. This dual-stage process eliminates filter clogging, reduces consumable costs, and keeps exhaust air visibly clean. Built from corrosion-resistant 201 or 304 stainless steel and equipped with explosion-proof motors and controls, the booth safely handles solvent-based, water-based, and anti-rust paints. Modular design and customizable lengths allow installation as a standalone manual station, a mobile repair booth, or an integrated segment of a painting line. With a closed-loop water system and simple sludge removal, it delivers long-term reliability, low maintenance, and fast return on investment for furniture, automotive, metal fabrication, and plastics finishing in hot, humid climates.

Dry filter booths clog rapidly with sticky overspray, causing production stoppages and high consumable spending. Basic water curtain cabinets without a swirl stage allow fine aerosol to escape, leading to visible emissions and duct fouling. In tropical humidity, dry filters also absorb moisture, collapse, or develop bacterial odors. High-volume spray operations need a non-clogging system that consistently captures both heavy wet mist and fine respirable particles without escalating operating costs.

This booth solves these challenges by intercepting large droplets with a full-width water curtain and then forcing the air through a specially shaped swirl chamber. Centrifugal force separates fine paint particles, which agglomerate and settle as sludge in the tank. No replaceable filters are needed — only periodic sludge skimming. The stainless steel construction withstands water, solvents, and cleaning agents for years. The integrated explosion-proof fan and water pump form a complete plug-and-play unit. The cleaned air can be recirculated indoors or ducted to secondary treatment, dramatically extending the life of downstream activated carbon filters or catalytic oxidizers.

*All units include explosion-proof motor and control box, integrated water curtain and swirl chamber, sludge tank, and M8 stainless steel bolt assembly. Custom lengths available.*

1. The explosion-proof fan creates negative pressure, pulling overspray into the booth.
2. A continuous vertical water curtain washes large paint droplets into the tank.
3. Fine mist enters a swirl chamber where high-velocity cyclonic mixing separates microscopic particles. Paint agglomerates and drops as sludge.
4. Moisture eliminators remove water droplets; clean air exits through the fan.
5. The pump recirculates water continuously. Sludge is periodically scooped out, with minimal water consumption.

1. Select booth width based on part size and operator workspace. Allow 50–100% extra width for comfort.
2. Match airflow to your open face area (face velocity 0.5–1.0 m/s). For enclosed spraying, consult our team.
3. Choose 201 SS for standard use, 304 SS for highly corrosive environments or frequent color changes.
4. Confirm 380V/3-phase power supply. Explosion-proof certification is standard for solvent paints.

Only periodic sludge removal. Scoop out settled paint sludge weekly or monthly. Water can be used for extended periods without changing.

Yes. The stainless steel and explosion-proof design suit both. Add a flocculating agent to aid sludge settlement for water-based paints.

Flush the curtain and swirl chamber with water. Smooth stainless surfaces prevent paint from drying and sticking. Sludge can be removed quickly.

No. Each booth includes an integrated explosion-proof fan. Only ducting from the fan outlet to outside or secondary treatment is needed.

Yes. The initial cost is slightly higher, but you eliminate filter replacements, reduce cleaning downtime, and avoid frequent fan repairs. Most users achieve payback within 12–18 months.
