CENTRIFUGAL HIGH-PRESSURE FAN. HIGH EFFICIENCY REVERSE-BLADE IMPELLER. DIRECTLY COUPLED MOTOR.

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 : High

• St. Pressure : 255 - 2550 mmH2O
• Impeller Dia : 630 - 1120 mm
• Air flow : 12 - 250 cmm

USAGE:

• For the suction of clean and dusty air. These types of high pressure fans are characterized by a high output with saving of electric power as they have a special fan wheel with reversed blades (Negative) assembled.
• These types of fans are particularly suitable for pneumatic conveyances, in cement factories, in the air feeding fo the cupolas in foundries and in oil burners, in the mills, in “pasta” factories, in chemical, metallurgical and iron industries where small capacities with medium and high pressures are required.
• For temperatures of the transported fluid higher than 90°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.
• The fan is revolvable.
