Spark proof construction: when explosive fluids are carried or when the plant is installed in dangerous environments, the parts that come into contact with the in taken fluid are constructed by material without iron content to avoid rubbing, motor on request is supplied in special construction.

Corrosion proofing construction: when corrosive fluids are carried, the parts that come into contact with the fluid are painted with special paints or they are constructed with special materials as austenitic stainless steels (AISI 304-316 etc.). Constructions can be effected according to the customer’s particular needs.

Technical Data

• Drive : Direct Drive
• Pressure : Low

USAGE:

• The high output centrifugal fans of this series are suitable for the suction of clean or plants slightly dusty air in civil and industrial air conditioning.
• The temperature of the fluid transported must not exceed 80°C without cooling fan and 150° C with cooling fan. For higher temperatures it is necessary to modify the construction of the fan. For temperatures of the transported fluid higher than 80°C up to 350°C a small heat stopping fan is splined to the shaft between support and scroll; besides the fan is painted with a special aluminium paint suitable for high temperatures.
• In particular plants for : ● Ventilation: stables, mines. tunnels. ● Suction: vitated air, welding fumes, vapours from solvent tanks and spraying booths. ● Aeration: storage bins, sheds. ● Cooling: plastic materials, cloths, glass plates. ● Drying: fodder, cereals. papers, varnishes, wood. ● Elimination: fumes and toxic gas.
• ● The fan is revolvable. Uses of Variable Speed Drives please pay attention to the possible overheating of the motor due to a lower rpm/Hz than recommended by the motor supplier.
