Product Overview: Achieve Superior Finishes with Hydro-Filtration Technology. The CoatTech Water Curtain Spray Booth is engineered for industries where surface quality and environmental compliance are non-negotiable. Unlike standard dry-filter booths, our system utilizes a continuous laminar flow of water to capture up to 98% of paint overspray. This ensures a dust-free environment, prevents filter clogging during high-volume production, and ensures your facility meets strict air emission standards.
