Abstract
A dry filterto be used in particular in underground mining and tunnel construction having a frame constructioninto which the required part housings-can be inserted from the side. The required partition wallis arranged so that an optimal large filtering surface is available both for the incoming raw gas and for the outflowing clean gas. Raw gas ductand clean gas ductrun horizontally one above the other and are separated from each other by the sloping. This means that a very large filtering surface is available.
