Apart from the standard suction machines we also have developed special machines for the electronics-industry. These have to fulfill some difficult to match standards like small use of ground space, absolutely low sound level, filtration of material with absolute filter and a simple waste disposal of the absorbed material outside the installation place of the machine. The use of groundspace amounts to only 500 x 500 mm, the height to 1700 mm. The filter installation is built as three-stage filter system and accommodated in the lower part of the machine house. As an extra a level guard is available consisting of an electronic scale, whereby only an alarm may be set off when filling is reaching maximum level, since the work of the production machine may not be interrupted. When the dust collector and/or filters are full, the container including dust bin and all filter installation is rolled out of the machine and serviced at a convinient place.
