Recommended for homes with 40 to 70 metres of pipe the SB40 is an octagonally shaped twin motor machine with a dust bucket collector. The machine is lined and comes with two mufflers to reduce noise levels. The dust collected is compacted on the bottom of the bucket through the technology of the octagonal shape and is easily disposed of into your rubbish bin. As the machine draws 10 amps it should have its own power circuit. Full specifications are shown on the specification sheet.
