Designed for car wash bays and auto detail shops and movie theater cleaning. Allow you to use your industrial carpet cleaning machine (like the Goliath) or truckmount and splits both the vacuum and solution for two upholstery or auto detail wands to be used at the same time. Designed to be used with electric machines that have at least 6 to 8 stages of vacuum (upholstery / hand wand use) or gasoline powered upholstery or carpet cleaning equipment. 2" vacuum "Y" with gate valve to turn off one user. Built in spray jet with ball valve can be turned on to spay water inside of the vacuum hose for dry dirt pre-vacuuming. Can be used as a dust downer/dampener device for air duct cleaning (single user on air duct jobs). Can also be used on 1-1/2" ID vacuum hose with optional AH46 hose cuffs. Option: Add a second 2" Gate valve so either operator can turn off their vacuum. Can be used in carpet cleaning use on truckmounts that use a 45/ 4005/ 4L blower or larger.
