3M™ Vacuum Hose connects 3M™ Random Orbital Sanders and Orbital Sanders to a self-generated or central vacuum system for dust extraction. The 1 in (25.4 mm) diameter hoses are available in standard or anti-static options and have 1 in (25.4 mm( exterior threads. The vacuum hose threads are left handed, which requires a counterclockwise rotation of the hose interface on the sanders for proper attachment.When used with 3M Central Vacuum ready tools and 3M Back Up Pads, the 3M Vacuum Hose provides a convenient way to connect between the tool and the central vacuum system. Dust extraction minimizes disc loading and improves abrasive performance, life, and productivity. An anti-static vacuum hose option is offered for operations where static charge buildup caused by dust moving through the vacuum hose is a concern. 3M Vacuum Hose Anti-Static 28730 is made of conductive materials that reduce the risk of static discharge. This results in fewer sparks, promoting operator comfort and improved safety. The black, anti-static hose has a 1 in (25.4 mm) diameter and is 4 ft (1.2 m) in length. It connects to a 3M Central Vacuum ready 3M Random Orbital Sanders or 3M Orbital Sanders. Standard vacuum hoses are designed for operations where static electricity or electrostatic discharge is not a concern. Whether operations require a standard or anti-static hose for dust collection, the 3M Vacuum Hose provides the connection between 3M Central Vacuum tools and workplace equipped central vacuum systems. When dust is generated by sanding, it becomes a layer between the abrasive and the work surface, loads the abrasive media and fills the air you breathe. Efficiently evacuating dust allows increased abrasive performance and life, optimizing productivity, and improving air quality. Designed to connect 3M Random Orbital and 3M Orbital Sanders to a vacuum system, these 3M Vacuum Hose are manufactured to the same high standards 3M demands of all its products. One small component of 3M's dust management solutions, the 3M Vacuum Hoses help businesses like yours achieve the best possible workplace environment and productivity results for the work you do.
