Dry vs. Water Spray Paint Booth: Key Differences Explained
Dry spray paint booth / water spray paint booth : what is the difference?
Dry Spray Paint Booth:
Working Principle:
Uses dry filters (like Andreae filters or fiberglass pads) to capture overspray paint particles from the air. Air is drawn through the filter media where solid particles are trapped, and clean air is exhausted.
Features:
Low water usage – No water required.
Easier to install and maintain.
Filters need to be replaced periodically.
Compact and more suitable for low to medium paint volumes.
Advantages:
Lower initial and operating cost.
No need for water treatment or sludge disposal.
Cleaner operation and less maintenance.
Ideal for smaller spray booths, woodwork, and intermittent painting operations.
🔹 Water Spray Paint Booth (Wet Type)
Working Principle:
Uses a water curtain or water wall to trap overspray paint particles. The air carrying paint particles passes through the water spray or curtain, and particles are scrubbed and trapped in the water tank.
Features:
Requires continuous water circulation.
Has pumps, water curtains, and sludge collection systems.
Best suited for high-volume painting operations and continuous production.
Advantages:
High efficiency in capturing fine and sticky overspray particles.
Can handle large paint loads without frequent maintenance.
Preferred for automotive, heavy engineering, and industrial applications with high paint usage.
