Recommended for homes with 40 to 70 metres of pipe the SB30 is an octagonally shaped twin motor machine with a bucket dust collector. Whilst this machine is lined to reduce noise the absence of a muffler does mean that it is fairly noisy and should be installed outside your living areas. The collected dust 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.
