Abstract

672,328. Air cleaners. BRITISH THOMSONHOUSTON CO., Ltd. Jan. 19, 1950 [Jan. 28, 1949], No. 1475/50. Class 8 (ii) An air cleaner comprises an open ended circular sectional casing 1, a coaxial inner casing 2 having an outwardly projecting conical end 19 and an intermediate air and dirt separating barrier 21 forming a dirt passage B and a clean air passage C. The casing 2 houses an electric motor which drives a fan 17 by which the dirt deflected by the cone 19 and a small proportion of the incoming air is drawn along the passage B and is discharged to waste through ducts 22, 23. The fan also draws the clean air along the passage C and delivers it to a clean air duct D.
