In this paper, an experimental study has been carried out to study the effects of volute tongue clearance and rotational speed on performance of backward curved blades centrifugal blower. The experiments are performed in the wide range of rotational speeds varying from 1500, 2000, 2500 and 2800 rpm with different volute tongue clearance blowers of 6%, 8%, 10% and 12.5 % of impeller diameter are used for experimentations. The experiments are performed with respective Indian standard IS4894:1987. To study the performance parameters flow rate, total pressure, shaft power and efficiency of the blowers. The aim of many different experimental tests is to validate whether the effects of different volute tongue clearance modifications and impeller speed to blower performance and to find a good volute tongue clearance and impeller speed matching to increase the performance of centrifugal blower. The results show that the volute tongue clearance and impeller speed has a significant effect on the performance of centrifugal blower.
