    The invention relates to a filter with an inner cavity delimited by an inner wall (1a) surrounded by an outer wall (1b), so that an intermediate cavity with a filter substance is formed between the walls. The inner and outer walls consist of permeable disc elements, where each disc element is closed into a tubular shape and held together in this shape by a locking strip (2a-b). The locking strips are placed so that they do not overlap each other, which means that the obstructing effect they have on the air flow is minimized. The locking strips can be placed 10 ° -350 ° from each other relative to the center axis, more optimally 90 ° -270 ° from each other and most optimally 170 ° - 190 ° from each other.

    Cylindrical filter with filter substance between two concentrically arranged gas-permeable walls The present invention relates to a filter according to the preamble of the independent claim.
    In particular, it relates to such an filter comprising an inner cavity to which gas is supplied or from which gas is discharged. Background of the Invention Cylinder filters comprise two permeable cylindrical walls, concentrically arranged one inside the other. An active alter substance is arranged between the two walls and gas which is supplied from an inner cavity is forced to pass through the intermediate cavity. The walls are typically made by bending rectangular plate elements into a tubular shape and locking in this position by locking strips. The locking strip constitutes an obstacle to the radial movement of the gas and impairs the gas flow and leaves the ublter substance in connection with the locking strips poorly utilized.
    An object of the invention is therefore to provide an filter so designed that it reduces the negative effects of the locking strips.
    These and other objects are achieved by a filter according to the characterizing parts of the independent claim. Summary of the invention The invention relates to a filter comprising an inner cavity delimited by an inner gas-permeable wall wall surrounded by an outer gas-permeable wall 1b, so that an intermediate cavity intended to contain an active .lter substance. The inner and outer wall members consist of permeable disc elements, where each disc element is closed into a tubular shape and held together in the form of a locking strip 2a-b. The locking strips are advantageously placed so that they do not overlap each other, which means that the obstructive effect they have on the air flow is minimized.
    In one embodiment the filter is designed so that it has a center axis, for example it can be varacylindrical, where the locking strips are so positioned that they occupy angular intervals relative to the center axis which are separated from each other.

    Claims (5)
    [1]
    A claim 1 comprising an inner cavity defined by an inner gas permeable wall (1a) surrounded by an outer gas permeable wall (1b), so that an intermediate cavity is formed between the walls to contain an active filter substance, wherein the inner and outer walls consist of permeabile disc elements, where each disc element is closed to a tubular shape and held together in this form by a locking strip (2a-b), characterized in that the locking strips are placed so that they do not overlap each other.
