Centrifugal extractor fan
Rosenberg Ventilatoren
rotor resistance, in connection with forward curved centrifugal
impellers, we developed a centrifugal fan series with extremely
high slippage characteristics. The external rotor motor
adjusts to the operating conditions and therefore changes the
R.P.M. at varying system resistances, regarding on the total
pressure. This is a special advantage in systems with variable
resistances occured from dirty filters, controlled dampers in
duct installations or clean-room applications.
Steep pressure-volume-performance curve
extremely low starting current
motor protection through thermal contacts as standards
Application:
Airconditioning, cleanroom technology, Commercial kitchen and gastronomy
