Washing boom is a fully stainless steel structure attached to the ceiling, aimed to ease up the washing process, avoid replacement of washing hose, reduce washing time, and give the workshop a better organised feel. Washing Booms are a critical piece of equipment for any car wash, but at first glance they seem so simple that many people don’t put much thought into what booms they choose. ATS ELGI’s Electro polished stainless steel washing boom has 360° high quality swivels with its ball bearing axel which can carry high pressure water or air.
