Product catalog summary

Introduction
This document is a catalog for the F-Series radial blowers by Elmo Rietschle, part of Gardner Denver. It provides detailed information on various models designed for vacuum and pressure operations, including single and multi-stage configurations.

Product Specifications
The catalog details several models of radial blowers:

F-CEV-S: Three to five-stage blowers for vacuum operations with capacities up to 8.9 m³/min and vacuum up to 115 mbar.
F-CEV-D: Designed for pressure operations with capacities up to 9.3 m³/min and pressure up to 125 mbar.
F-CEVF: Multi-stage blowers for vacuum operations, suitable for removing fine materials like paper dust.
F-RER and F-REL: Single-stage blowers for both vacuum and pressure operations, offering high volume flow at small differential pressures.

Applications
The blowers are suitable for various industrial applications, including the printing, woodworking, textile, environmental engineering, and packaging industries.

Operating Principle
The radial blowers operate by rotating an impellor, moving air centrifugally outward through blade chambers, creating a vacuum that draws air in from the inlet port. The air is then directed into a spiral housing where its velocity is reduced, converting kinetic energy into pressure energy before exiting through the outlet port.

Advantages
The blowers are noted for their robust construction, economic operation, quiet and vibration-free performance, and low maintenance requirements due to greased-for-life bearings. They offer flexibility in installation and are available with variable speed drives.

Selection and Ordering Data
The catalog provides detailed selection and ordering data for different models, including motor specifications, weight, sound pressure levels, and performance diagrams for both 50 Hz and 60 Hz operations.

Specifications
The document provides a detailed list of motor protection switches with specifications including amperage range, starter casing, lockable start button, and overload switch.

Procedures
The document outlines the use of direct online motor starters fitted with thermal overloads to protect electric motors from overloading by limiting operating current.

Dimensions
Dimensions for various radial blowers and accessories like silencers are provided in millimeters for different models and configurations.

Conversion Tables
Includes conversion factors for pressure, suction capacity, power, mass, and length.

Standards and Regulations
The document states that the products listed do not require export permits under current German and US regulations, unless specific country restrictions apply.

Quality Assurance
Emphasizes the commitment to high-quality standards and notes that product features may change due to ongoing development.

Annex
Includes additional information such as conversion tables, conditions of sale and delivery, export regulations, certified quality, and Gardner Denver locations.

Quality Assurance System
The document outlines a comprehensive quality assurance system that monitors all phases from development to delivery, adhering to ISO 9001 and 14001 standards.

Certified Quality
Elmo Rietschle products are associated with certified quality, supported by a network of manufacturing and service locations worldwide.

Global Presence
Gardner Denver has a global presence with corporate headquarters in Quincy, Illinois, and locations worldwide, ensuring proximity to customers and familiarity with local conditions.

Operating Range
The document includes technical specifications for Elmo Rietschle products, detailing pressure and vacuum ranges, volume flow, and suction capacity across various product types.

Funktionsprinzip Operating Principle Bei einer Drehbewegung des Laufrades bewegt sich die Luft in den Schaufelkanälen (1) des Laufrades (2) zentrifugal nach außen und tritt am Umfang des Laufrades (3) aus. Folglich entsteht an der Nabe (5) des Laufrades ein Sog, der bewirkt, dass von der Eintrittsöffnung (4) Luft nachströmt. Die nachströmende Luft wird von axialer in radiale Richtung umgelenkt und tritt in die Schaufel kanäle (6) ein. Von dort dringt sie auf Grund der Zentrifugalkraft am Laufradumfang nach außen in das Spiralgehäuse (7). Hier verzögert sich die Strömungsgeschwindigkeit: Ein...
