Csőventilátorok

Casing

The casings are made of galvanised sheet steel. The fans are only suitable for indoor installation.

Impellers

Backward curved high-performance impellers made of plastic are used. The impellers are mounted directly on the rotors of the external rotor motors and are dynamically balanced on two levels with the rotor according to quality level G 2,5 / G 6,3 as per DIN ISO 21940-11.

Electrical connection

The electrical connection is made through a terminal box mounted on the casing with protection class IP54. The built-in motor protection is signalled via a digital output or a pulse output.

Assembly

Rigid folded spiral-seam tubes (Spiro), flexible aluminium or plastic tubes with standardised diameter can be used. Rosenberg tube fans can be used in all mounting positions. When used over several floors of a building, the local fire safety regulations must be observed.

Impellers

Up to size 315L, backward curved high-performance impellers made of plastic are used, from size 355, backward curved, high-performance impellers made of aluminium are used. The impellers are mounted directly on the rotors of the external rotor motors and are dynamically balanced on two levels with the rotor according to quality level G 2,5 / G 6,3 as per DIN ISO 21940-11.

Casing

All sizes have an elegant, high-impact, flame-retardant plastic housing with an integrated terminal box IP44 and guide vanes.

Impellers

The impellers up to size 250 are made of plastic and from size 315 are made of galvanised sheet steel. The impellers are mounted directly on the rotors of the external rotor motors and are dynamically balanced on two levels with the rotor according to quality level G 2,5 / G 6,3 as per DIN ISO 21940-11.

Casing

The casing is made of galvanised sheet steel. The 40 mm thick mineral fibre plates inserted act as sound insulation. The cover can be simply screwed off making the fan area easily accessible for cleaning and maintenance. The fan inside can be disassembled.

Impellers

The fans are driven by an external rotor EC motor, fitted in the centrifugal impeller. EC Zeroboxes of type EVOLUTION up to size 250 have a forward curved centrifugal impeller, from size 315 backward curved centrifugal impellers are used. All sizes of type REVOLUTION have backward curved impellers.

Electrical connection

The electrical connection is made through a terminal box mounted at the housing. The built-in motor protection is signalled via a digital output or a pulse output.
