Centrifugal fans are classified into three main groups; low, medium and high pressure.

DESIGN

The design is based on three main groups, low, medium and high pressure.

The fan impeller is designed and shaped in accordance with its application, conditioned by the required air volume and pressure drop.

The impellers are classified into four main groups. Also tailor made solutions are avaliable like spark proof design.

EXECUTION

LSV and MSV are manufactured in sea water resistant aluminium and painted.

Stainless steel / Aisi 316 execution or steel, galvanized or painted are delivered on request.

The impeller is made of salt- and ammonia resistant aluminium, aerodynamically shaped and balanced. In four main groups:

Type B: Backward, convex curved blades

Type F: Forward curved blades, Sciroccio wheel

Type Z: Backward, concave curved blades, self cleaning

Type R: Radial blades, for transportation fan

The air capacities vary from 1000 to 240 000 m3/h.

ELECTRIC MORTOR

The fans are usually supplied with standard squirrel caged inductive electric motor. They may also be supplied with other types of electric motors, like explosion proof or 2-speed motors.
