Industrial Pre-Treatment Wash Booth

An industrial pre-treatment wash booth is used for cleaning and preparing materials prior to applying the powder or liquid coating finishes. An industrial wash booth is typically used before or after the parts of the machine are manufactured. Parts requiring superior corrosion protection, such as automotive parts, wheels, appliances and office furniture often require multiple washer stages. There are many different types of industrial wash booths and pre-treatment areas.
