  • the fans are in most known extraction systems arranged in front of the filter unit in the raw gas area. So it will the polluted air is blown into the filter system. In the last The fans are often behind the filter system arranged. So it becomes the polluted air through the filter system sucked.
  • the arrangement of the fans on the Clean gas side a higher efficiency of the fans can be achieved, the wear of the fans is kept low and the risk of explosion from particles in the air reduced.
  • there are all material leading System parts in the vacuum area so that dust escapes leaky pipes is avoided.
  • a common line usually runs from the filter system, which is divided into a line to each fan becomes. After the fans, individual lines lead to one Collective line, which is in a changeover flap for return air or exhaust air ends. The clean air can be blown directly outside in summer or if necessary, e.g. during the heating season, over the Return air duct can be returned to the factory hall.
  • the different Lines can be produced with great effort and require higher maintenance. To lock the lines, if the fans are not in operation, must be in the individual lines pneumatic locks are arranged, which the Further increase manufacturing and maintenance costs.
  • the object of the invention is therefore a fan device for suction systems that are easy to manufacture, has low susceptibility to failure and requires little maintenance.
  • the object of the invention is achieved in that all suction lines all fans and the or each supply line for the air to be extracted into a common airtight suction chamber flow out, and that all exhaust pipes of all fans and at least one collective exhaust pipe in a common, airtight Pressure chamber open.
  • This construction eliminates one costly. Piping of the individual fans on the intake side. By eliminating individual feed lines to the fans do not have to be in the individual lines Locking devices are provided with which in the case the associated line is closed when a fan is not in operation can be so that this line is not with material is relocated.
  • Through the opening of all exhaust air ducts in one Common, airtight pressure chamber can also be on the exhaust side of the fans, i.e. on the pressure side, the manufacturing effort compared to conventional systems.
  • the invention Construction is easier to manufacture, less prone to failure and requires less maintenance.
  • the arrangement of devices for sound attenuation in the collective exhaust line causes a reduction in the outside noise level. Especially when the air e.g. to It is important for heating purposes to be returned to the factory hall that no or only this will result a negligible noise level is caused. But also with the air line to the outside it is also essential, especially in built-up areas, to develop noise as much as possible to keep low.
  • the suction lines of the fans are advantageously equipped with suction nozzles or the like. if necessary, provide a protective grille. This will reduce the intake pressure loss of the fan kept low and a safety for maintenance personnel due to the protective grille guaranteed.
  • the airtight suction chamber and possibly also the airtight one Pressure chamber formed by a housing, the walls and connections of which are airtight are executed.
  • both an airtight suction chamber and one Airtight pressure chamber can also be formed by a common housing be, the suction chamber and the pressure chamber airtight by a wall are separated from each other.
  • the drive units, especially the drive motors, of the fans at least are partially arranged outside the housing so that they are accessible from the outside Maintenance and replacement of the drive units are possible without great effort.
  • the inside of the housing is advantageously lined with a sound-absorbing material or surround. This will lower the acoustic level in the case and after scored outside.
