A permanent dust extraction network does help with safety in a workshop, getting the hoses off the floor and out of the way. It can however limit the use of a dust wand or simple additions to the network.
With the use or a blast gate, to close off the line or open it up for use, you can add a hose as a temporary or permanent fixture, and have it securely mounted to the wall. Simply use a 4” hose clamp to connect the hose so it is ready for use. Pan head screws are advised over countersink screws.
These blast gates are self cleaning, preventing a build up of debris, and preventing the gate from closing, which is a common cause of poor suction with dust extraction.
