» Design and Downloads
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 G2.5 as per DIN ISO 1940.
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.

» Design and Downloads
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 up to size 250 have a forward curved centrifugal impeller, frome size 315 backward curved centrifugal impellers are used.
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.
Assembly
Rigid folded spiral-seam tube (Spiro), flexible aluminium or plastic tubes with standardised diameter can be used. Zeroboxes can be used in all mounting positions. When used over several floors of a building, the local fire safety regulations must be observed.

Casing
The casing is made of galvanised sheet steel. The 40 mm thick mineral fibre plates inserted in the Evolution Series act as sound insulation. The cover can be simply screwed off, making the fan area easily accessible for cleaning and maintenance. The motor can be disassembled with impeller and spiral casing.
Impellers
External rotor motors are used in protection class IP44/54 with humidity protection, ball bearing-mounted and with built-in thermal contacts for motor protection. In the Evolution version, the impeller is forward curved and has double-sided inlets. 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 G2.5 as per DIN ISO 1940.
Electrical connection
The electrical connection is made through a terminal box with protection class IP44.
