FILTER DEVICE, METHOD OF MANUFACTURING THE SAME AND METHOD OF REPLACING A FILTER DEVICE

摘要

The present invention generally relates to improved filter devices that allow a safer filtration and in particular a safer replacement of the filter. The filter device of the invention is adapted for filtering fluids flowing into or out of a fluid duct. The filter device comprises a container having one or more walls, wherein at least one of the walls comprises at least one filter element forming at least a portion of the wall. The container defines an interior adapted for collecting contaminants in the fluid. Furthermore, the container comprises one or more openings and means adapted for sealingly and removably connecting the filter device to the fluid duct at at least one of the openings, so as to provide fluid communication between the interior of the filter device and the fluid duct. The openings that are to be connected to the fluid duct are adapted for and/or comprise means for closing when the filter device is removed from the fluid duct.
