We have designed and manufactured a variety of single and three phase vacuum units specifically for the car wash market. We have single phase machines for car washes who do not have three phase electricity. We have three phase machines for car washes who do have three phase electricity. The machines can be either be supplied with a frame or a cabinet. If the unit is supplied in a frame, you will need this to be in a secure dry place. Rigid pipes will run to the vacuum points. If the unit is supplied in a cabinet, this will be secured to the ground and the vacuum points are on the side of the machine, no need for lots of rigid ducting.
