RING • Ring axial roof units

Cased axial duct fan
IP55

Datasheet

RING line is ideal when large air capacities are required; in applications for wall, panel or duct fixing. For instance: ventilation of industrial buildings, car parks, stock farms, cooling of electric and refrigerating equipments etc.

Application

ROOF-AM line is designed to extract large volumes of air in roof installations, without long ducts. For instance: ventilation of industrial buildings (factories, warehouses etc.), stock farms and electrical equipments etc.
