Karcher vacuum to Cyclone with PRV by paulrbarnard

Last crawled date: 4 years, 7 months ago

This is an adaptor to connect a Karcher WD3 vacuum hose to a dust extraction cyclone with a 56mm connector (standard cheap Chinese type). This is the part that goes between the cyclone and the vacuum. I have incorporated a pressure relief valve to prevent the dust collection bin from collapsing if the inlet hose gets blocked.
I posted a simple version without pressure relief a few months ago.
