Abstract

PURPOSE:To improve the performance of a blower by inserting the end of a intake port ring inside the intake section of the intake side plate of an impeller and providing an annular wall concentrically with the center of intake port ring outside the intake section of said side plate to reduce air contraflow from the intake port into the impeller. CONSTITUTION:An end 9a of an intake port ring 9 is inserted inside an intake section and the outer peripheral portion 9b is secured fixedly to the front wall 5 of a casing. An annular wall 10 is provided concentrically with the center of intake ring 9 outside an intake section 3a of the intake side plate 3 to be secured fixedly to the intake port ring 9. Also, the inner diameter D0 of the end 9a of intake port ring and the inner diameter D2 of annular wall are set to the following relationship therebetween D0 D1+D2/2.
