Specifications

Housing

Base, windband and weather cap are manufactured from thermo formed UV stabilised polymer. Impeller and
motor assembly are supported by a galvanised steel chassis for stability and ease of service. Bird mesh is
standard.

Impellers

Ziehl mixed flow impellers are manufactured from plastic or aluminium for low rotational mass. The rotor /
impeller assembly is balanced as a complete assembly to ISO1940 Grade 6.3 or higher.

Motors

Motors are manufactured by Ziehl and are of external rotor design. Motor enclosure features IP54/IP44
(exe) protection. Motor windings incorporate class ‘F’ insulation as standard although class ‘H’ is ready
available. Motor bearings are maintenance free ball bearing design. Auto-reset thermal contacts are
generally provided, either integrally wired or terminated at wiring connection bar.

Testing

Rated fan performance has been determined by testing to DIN24163 1998.
Fan sound data has been determined by testing to DIN45635.

Wiring Diagrams

It is the responsibility of the user to connect the thermal contacts where provided to protect the motor.
Failure to do so will void the warranty on the motor.
