The two part container has several suction units. There is one arrangement with filter for removing particles from the air and another arrangement with filters for removing gases. The filters generate in conjunction with openings in the channel, in the respective arrangmeents. The filters can be changed via the opening in the container. The suction arrangement removes air to produce a reduced pressure in the container. Air enters via passage which is connected to the particle - removing unit. The air enters tangentially and passes through the stack of cartridge filters. It then passes through a fire filter. Cleaned air leaves via the perforations and suction unit.
