Abstract

Separator to remove dust from gas streams has a central cyclone unit with a tangential inlet branch. The centrifugal action causes the bulk of the dust to fall down the leg of a cyclone into a collector. The air passes up through a central shaft into a mantle and then flows down the inside of tubular filter sleeves. Cleaned air passes out into the shell of the separator and is exhausted by a fan. For separating dust from dust laden air e.g. in rock drilling.
