The 94302 Conductive Dust Extraction Adaptor Set is a specifically engineered solution to cater for the extraction of dust from power tools to avoid and remove airborne particulate. This set allows the user to connect their adaptor to any 32mm hose, taking advantage of the clip ring system to quickly swap bayonets over to cater for power tool exhaust port sizes. Two soft TPE moulded adaptors are provided in this set to cover 25mm, 35mm, 38mm and 48mm power tool vacuum exhaust ports. The 25-35mm adaptor caters for smaller tools such as sanders, whereas the larger 38-48mm adaptor caters for tools such as bandsaws and work shrouds. Another advantage to the 94302 adaptor set is the air relief which allows the user to adjust the suction from the vacuum to the power tool. Particularly with sanders, when consulted with woodworkers their main issue was sanders sticking and swirling, solves this issue by allowing the user to adjust to relief suction from the vacuum.
