Wood workshops are exposed to a severe ambient of polluted air, and consequently has been associated with increased lung cancer incidences. Current case study proposed a new design for dust collector fan impeller to purify and increase air quality in such harsh working areas. In-House lower cost Centrifugal Blower (CB) was designed, manufactured, and tested for its performance. Such CB mainly consists of one impeller equipped with symmetrical backward - curved centrifugal blower vane, mounted on a rotating shaft and enclosed by a casing. Polluted air is axially drawn to the impeller’s eye for energy exchanging along the rotated backward – curved vanes. Experimental measurements were recorded for the flow velocity and pressure at the inlet’s eye and the outlet port, at different rotary impeller speeds in the range of 200 to 2,850 rpm. Numerical results and simulations, have shown better performance and 97% correlation between the polluted air pressure with its flow rate of the impeller dust blower fan.
