F-RER / F-REL 620 50 – outdated model
The radial blower F-RER / F-REL 620 50 is no longer part of the current Elmo Rietschle range; the manufacturer names no successor in its current documents. RER denotes the clockwise-rotating version, REL the counter-clockwise-rotating version; the blowers were ordered by the type designation RER/REL 620 50, and the manufacturer did not publish order numbers for them. At 50 Hz, the single-stage radial blower for vacuum operation reaches a volume flow of up to 57.0 m³/min (3420 m³/h) and a maximum static pressure difference of 71.9 mbar, at 60 Hz up to 40.0 m³/min (2400 m³/h) and a maximum of 95.5 mbar. At an ambient pressure of 1 bar this corresponds to an ultimate pressure of 928.1 mbar absolute at 50 Hz. The speed is 2850 min⁻¹ at 50 Hz and 3450 min⁻¹ at 60 Hz. Radial blowers must only be operated throttled so that the motor is not overloaded. Volume flows and pressure differences are taken from the Rietschle data sheet D 750–753 (edition 1999); motors, weights and sound pressure levels from the Elmo Rietschle F-Series catalogue (2009).| Pumping speed 50Hz | 3,420 |
