Abstract
A gas-moving device comprises (a) a rotor which comprises a plurality of fibres, filaments, tapes, ribbons, strips or sheets which are mounted such that on rotation of the rotor they move in one or more planes which are substantially transverse to the axis of rotation of the rotor and draw gas into the device and cause it to flow away from the said axis towards the radial periphery of the rotor; (b) one or more gas inlet zones; (c) one or more gas outlet zones; and (d) means of rotating the rotor. The device may be provided with delivery means through which a fluid may be charged to the rotor, which fluid reacts with and removes impurities from the gas.
