The SG-10 with carbon filter for uses involving chemical materials to be extracted. Like all Wassermann suction units, this has the reliable low-pressure priniciple; It sucks up the maximum amount of air at a very low air speed resulting in relaxed and quiet working conditions. A further advantage is the high suction volume, where the hands do not become cold, even with continuous operation. The fan motor is a squirrel-cage motor, almost free from wear and maintenance free. Measures 270mm (L) x 348mm (W) x 672cm (H). Weighs 8.9kg. See page 66/67 of the catalogue below for more information and scroll down for further options.
