This is 12M 35mm premium quality ducted vacuum switch hose, with durable bent end piece and ergonomic handle. The switch on the handle turns the ducted vacuum system on and off via low voltage cables that are moulded into the construction of the flexible hose. The hose plugs into PVC wall inlets and aligns with the two little pins, via an indentation or guides standard in all PVC ducted vacuum inlets.
We recommend 35mm hose to prevent air losses from the internal surfaces that are more pronounced in switchable hoses used for ducted vacuum systems.
This switch hose fits most popular ducted vacuum brands such as: AstroVac, Auskay, AussieVac, Beam, CentralVac, Cyclic, CycloVac, DAS, Electrolux, Electron, EVS, Hills, Hoover, Hurricane, iCentral, Lux, Monarch, Premier Clean, Pullman, Silent Master, SmartVac, StarVac, Vactron, Vacuflo, Vacumaid, Valet and Volta.
Please note that the ON/OFF switch on the handle will only work if the hose is plugged into the commonly used dual-pin inlet. If you have an older ball-bearing inlet, the hose will still start the machine whenever you plug the hose end into the wall inlet, but you won't be able to control the machine from the handle.
