[:en] Many people speculate about the confusion on what is considered a compressor, a blower, or simply a fan. Purpose 1.1 Purpose. Centrifugal blowers can pull vacuum on processes and produce positive pressure. Figures A.1 to A.5 of Appendix "A" present the typical characteristic curves for radial, backward and forward bladed fans respectively. The centrifugal blowers are classified according to the direction of the blade curvature with respect to the rotation of the wheel. %%EOF endstream endobj 101 0 obj <>>>/Filter/Standard/Length 128/O(d�W{LZ�|w����\n�'�:`ך�U4�6�)/P -1324/R 4/StmF/StdCF/StrF/StdCF/U(��p6�\n �XIY�� )/V 4>> endobj 102 0 obj <> endobj 103 0 obj <> endobj 104 0 obj <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]>>/Rotate 0/Thumb 42 0 R/TrimBox[0 1.086 612 792]/Type/Page>> endobj 105 0 obj <>stream The RBX-Series offers up to 8 CENTRIFUGAL BLOWER 9502 9505 9503 9505-50 9503-AU 9507 9503E 9508 9504 9512 9504-50 9512-AU 9504-50E 9512E Read and understand all instructions before using this product.
