ABSTRACT:
A filtration device for liquids is provided and includes a filtration beaker filled with a filtration material and a lid. The lid is connected to the filtration beaker in a liquid-tight manner to define an inner volume, and includes at least one liquid inlet and at least one air vent. A sieve-like textile fabric is disposed in between the filtration beaker and the lid. In order to guarantee secure operation and ensure a good retaining effect with respect to particles having a size of approximately 200 micrometers at different filtration-material fill heights in the filtration beaker, the sieve-like textile fabric has at least one formed part protruding into the inner volume of the lid, whereby air can be found on both sides of the part of the textile fabric which is located farthest away from the filtration beaker.
