Water Wash Paint Booth

Introduction of Water Wash Paint Booth

The water wash paint booth is a modern coating technology designed for large-scale industrial painting facilities, offering an optimal working atmosphere for the application of liquid paint sprays. Thanks to the constant water curtain used in these booths, the equipment manages to extract and clean the toxic overspray of paint from the air before it gets released back into the shop and the environment. Our water wash technology provides the best possible continuous filter performance, which is considerably better than the traditional dry filters, minimizing any necessary downtime for filter replacements.

Built from durable materials such as heavy-gauge galvanized or optionally stainless steel, our water wash paint booths can withstand even the toughest conditions and will serve you well for many years. The benefits of the investment are evident from the beginning – lower operating expenses as a result of no filter replacements, easier hazardous waste disposal, and compliance with the strict standards of EPA and OSHA. By choosing the best liquid spray booth solution for your shop, you will be able to boost productivity, create a safe working environment for your employees, and provide the best quality of your product to your clients.

Technical Specifications of Water Wash Paint Booth

Our wash paint booths have been specially designed to provide optimum performance and reliability. The technical specifications for our range of wash paint booths are listed below in the table. Custom design solutions are also available.

The Working Principle: How Our Water Wash Paint Booth Operates

A​ water wash paint booth is specifically made to offer a secure, hygienic, and environmentally friendly setting for the large-scale finishing of liquid spray. The main job of such a booth is to swiftly grab and filter the paint overspray suspended in the air by means of an advanced water purification system. Not only does this method help in safeguarding the personnel and the surroundings, but it also guarantees a top-notch finish by preventing the new coatings from being spoiled by unwanted paint. The work operation is non-stop, robotic, and made for industrial performance.

• Generation of Controlled Airflow: A robust and spark-less blast fan positioned at the back end of the booth is the cause of a uniform, laminar air movement. This regulated oxygen stream moves from the face of the booth, after the object to be painted, and finally to the water curtain wall, in an orderly manner, throwing all paint overspray away from the operator and the item.
• Overspray Acquirement through Water Curtain: At the time of the overspray-laden air being drawn to the exhaust plenum, it is compelled to enter a streaming sheet of water all the time. This "water wall" or "water curtain" serves as the main filtration step. The very active water flow, sometimes resembling the air turbulence, results in the water effectively "scrubbing" the air, and most of the paint particles are held at the first contact.
• Particulate Scrubbing and Separating: The air first goes through a sequence of internal baffles and scrubbers behind the water curtain, where even more turbulence is created. This very energetic scrubbing is unavoidable in the final contact between the polluted air and water; the result is that all the remaining paint particles get mixed up into the water solution.
• Sludge Collection and Management: The paint particles, which are captured along with the water mixture, drop to the collection tank or sump at the bottom of the booth. In this place, separation of paint solids from the water takes place, thus forming the sludge. In case of a need for heightened efficiency, the addition of chemical agents (flocculants) to the water results in faster separation, provoking paint sludge to coagulate and be easily removed and discarded.
• Water Recirculation System: A big pump keeps the water, which has been filtered in the collection tank, on a continuous path from it to the header of the booth so that the water curtain is steady. Compared to non-recirculating designs, this closed-loop system remarkably lessens both water usage and operational expenses.
• Ultimate Filtration and Discharge of Clean Air: The air, which has been scrubbed before leaving the building, is made to flow through another portion of the eliminator plates or mist filters. These parts are chiefly built to trap any remaining water droplets so that only clean and moisture-free air is emitted to the atmosphere that satisfies or surpasses EPA and OSHA rules concerning particulate emissions.
