Statfield’s pedigree is the proof that our expertise and resources can handle these requirements effortlessly. Statfield’s booths have proven leadership for 4 decades in the field of surface coating application technologies.
A Booth is critical for ensuring a pollution-free environment during operation. It is basically used to arrest over sprayed paint efficiently which is harmful to environment.
Selection criteria
Selecting an appropriate type of booth for the operations depends on factors such as article size, production, type of paint, its consumption, type of application, number of operators etc. In instances where water is not available naturally, metallic or absorptions filters are used. Normally Dry Booth is recommended if paint consumption is low. Water Wash Booth is preferred when higher volume of paint demands higher paint killing. The Down Draft version in both cases is needed for large / heavy articles so as to coat article from all sides.
Types of Booth
Statfield offers two types of booths :
• Water Wash Type
• Dry Type
Water Wash Type
Side-Draft : The over sprayed paint is dragged towards the water flowing continuously over the screen. The turbulence is created below the screen & sludge is formed. The water and the sludge are separated in the filter at the bottom tank. The clean water is pumped again to the top tank and flows over the screen. The air is sucked by the blower through the baffles wherein the last paint particle is separated. The baffles are very effective and can be removed, cleaned easily. The booth is very sturdy and used for heavy production schedules. It has more efficiency as compared to the dry booth. The blower is mounted on the separate structure. The sound level is as per norms.
Down Draft
The booth is available in water wash and dry versions. Here air draft is created downward. Article is normally kept stationary and the operator moves around. Over sprayed paint is dragged towards bottom. Material movement can be on ground trolley or by overhead conveyor.
Additional Features:
Pressurisation can be provided if required for additional dust protection.
For better paint results, humidity control with heater/chiller can be provided.
To arrest paint fumes additional absorption filter can be given.

Down Draft Side Draft Combination Booth
The combination of down-draft and side draft is used to achieve the advantages of both technologies. A separate water wall can be provided at the back or side of the booth for painting the small jobs. Down-draft booth is given for bigger jobs. These types of booths are also used where production is very high and number of operators painting at the same time is more.
