Harmann VIVER/VIVER.P
A fan with vertical air ejection
Roof radial fan with vertical ejection and motor placed in the stream of flowing air. The casing is made of high quality aluminum alloy resistant to weather conditions (AIMg3), in the shape of an octagon with a grid. Placed on a square mounting plate made of galvanized sheet steel.
The construction of the fan allows mounting on a roof base or a brick pedestal with a square cross-section. Around the profiled inlet to the rotor, threaded connections have been placed that allow the installation of roof accessories.
The VIVER.P models are equipped with an integrated service switch located on the housing.
Impeller dynamically balanced (double balancing grade G 6.3) type B with backward tilts.
The drive is realized by single-phase (230V, 50Hz) or three-phase (400V, 50Hz) asynchronous electric motors with a rotating housing, with integrated thermal protection (winding temperature sensor with automatic reset – up to model 355 inclusive) or with external thermocontact terminals. Motors adapted for voltage speed control in the range of 80-230V (single-phase models) and 100-400V (three-phase models).
Degree of protection for the device: IPX4
Engine protection degree:
– IP33 – for models 220-315
– IP44 – for the 355 model
– IP54 – for models 400-560
Insulation class: F
