Rectangular duct fans of the SVF and SBV series are recommended for use in exhaust and supply ventilation systems with a large length of air ducts and high aerodynamic drag.
The impellers of the fans are made of galvanized steel sheet and have forward-curved blades. Fan impellers are statically and dynamically balanced.
SVF fans are equipped with induction motors with external rotor of protection class IP 54. To protect the fan against overheating there are thermal contacts with terminals in the motor windings for connecting of an external motor protection device.
SBV Series
The fan case is made of galvanized steel, has a layer of sound insulation of mineral wool with thickness 50 mm. The impellers of the fans are made of galvanized steel sheet and have forward-curved blades.
Fan impellers are statically and dynamically balanced.
SBV fans are equipped with motors with an external rotor of protection class IP 54. To protect the fan against overheating there are thermal contacts with terminals in the motor windings for connecting of an external motor protection device. When using frequency conversion min. frequency is 30 Hz!
