ROOF-CM

Horizontal discharge centrifugal roof fan

ROOF-CM line has been designed for roofing installations, for direct or ducted exhaust in civilian, commercial and industrial buildings, as: offices, restaurants, hotels, shopping centers, warehouses , industrial plants, engine rooms etc

  • Available in 10 sizes with impeller diameter from 310 up to 800 mm, and 4, 6, 8 pole motors.

ROOF-CM fans are characterized by the backward curved blade high efficiency impeller and extremely wide radius inlet cone guarantee of high capacities and pressures with limited noise levels. The accuracy of the design of the cap, with square section, confers to the fan a particularly pleasant aesthetic impact, easy to be installed in every architectural contest guarantying the optimum cooling of the motor. The protection guard in steel rod offers less resistance to the airflow when compared to the grids normally used and the best self-cleaning effect. The electric motor is manufactured according to the international standards guarantee of reliability and sturdiness, ease of maintenance and replacement.

  • Backward curved blade impeller, high efficiency in galvanized steel sheet. Balancing according to UNI ISO 21940-11.
  • Fixing base, with inlet cone, in steel sheet protected against the atmospheric agents.
  • Protection guard in steel rod protected against the atmospheric agents.
  • Cover in techno-polymer.
  • Asynchronous electric motor mono phase or
  • Three phase, outside the airflow, IP 55, insulation cl. F, service
  • S1, according to IEC/EEC/UNEL MEC.
  • Arrangement 5; directly coupled to the motor shaft.
  • Temperature conveyed air: -20°C / +80°C.
  • Voltage:
    • Mono phase version (M) 230V – 50Hz.
    • Three phase version (T) 400V – 50Hz.

ROOF-AM

Ring axial roof fan – “IEC” motor

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.

  • Available in 8 sizes with impeller from 450 up to 1000 mm.

This line is characterized by the wide round shaped nozzles in both inlet and outlet, warranty of reduced noise level and high efficiency. Besides these fans allow the effective operation either in exhaust or supply duty. Electric motor is easily accessible for wiring and maintenance operations, manufactured according to international standards assuring reliability and the long-term economic recovery of the unit simply repairing or replacing the motor itself.

ROOF-AVS

Axial roof fan vertical discharge with shutter

ROOF-AVS line is designed to extract large volumes of air, in roof installations. For instance: ventilation of big industrial plants, hangars, power plants etc. It consists of an outer casing, containing the gravity shutter, below which a RING fan shall be fixed. The shutter opens thanks to the airflow generated by the fan and closes by gravity, preventing rain and wind entrance from outside and the dispersion of heat from inside.

  • Available in 6 sizes with impeller diameter from 560 up to 1000 mm.

The main characteristic of this line is the higher efficiency if compared with the axial roof fan with horizontal discharge, due to the lower resistance of the gravity shutter compared to the cap.

  • Outer casing (AVS) with steel sheet panels including base, protected the atmospheric agents.
  • Gravity shutter with aluminium fans.
  • Outlet protection grid protected against the atmospheric agents.
  • Inlet nozzle
  • Axial fan series RING (description and performances as per RING catalogue section), protected against the atmospheric agents, impeller with airfoil profile blades, variable pitch angle in still position, in techno-polymer and hub in die cast aluminum alloy. Asynchronous three-phase electric motor, protection IP55 Is. class F, service S1, construction according to IEC/EEC (UNEL MEC).
  • Predisposition with loose cables for connection outside the roof-fan or internally in the building
  • Arrangement 4 (directly coupled with impeller).

ON REQUEST

  • Versions with die-cast aluminium blades.
  • Predisposition with inlet flange, DUCT-type, for ducting versions (see DUCT accessories)
