Abstract: Rotary filter including a perforated, rotatable drum and at least one blowback valve located in close proximity to the interior surface of the drum. In a preferred embodiment, the blowback valve includes an opening adjacent the drum for the discharge of a gas and the opening includes at least one radial position adjusting device alignable with a hole in the perforated drum, whereby the radial position of the blowback valve in relation to the interior of the drum is adjustable externally through perforations in the drum. The external adjustment permits drums longer than possible with prior art rotary filters.
