It is therefore the analysis of one, say centrifugal compressor, will also holds good to the other machines like blower, fans. 140 0 obj <>stream They are also used to produce negative pressures for industrial vacuum systems. Model PB Catalog 23 page catalog in .pdf format. These blowers can be used in a fixed position or mounted on moving parts, and are optimal for local cooling and airflow through ducts. Figure 1 Centrifugal Fan Figure 2 Axial fan Each fan system has different types of wheels, or impeller types: Centrifugal impeller styles. A centrifugal blower draws in the air through the inlet axially (in parallel) to the drive axle, deflects the airflow 90 degrees through the rotation of the impellers and extracts it radially. 4 Tliisprieipleisapparentlyperfectandwouldundoubtedly yieldgoodresultsiffrictionandleakagecouldbeeliminated. So they are classified as forward curved blade, backward curved blade or radial blade blowers. Centrifugal blowers can pull vacuum on processes and produce positive pressure.
