Application

Characteristics of the fans (pressure and output) make them suitable for any types of general ventilation systems. Owing to their construction and low noise level the KEF fans are dedicated to use in kitchen hoods and in small bars and restaurants.

Construction

A radial, directly driven fan. Housing made of galvanized steel sheet, painted grey (RAL 7042), with acoustic and thermal insulation. Rotors: in models 160, 200, and 250 provided with forward-tilted blades type F, welded, made of gavlanized steel sheet; in model 315 – provided with backward-tilted blades, welded, made of aluminum sheet.

The rotors are dynamically balanced as per ISO ISO1940. The motor is mounted on pivoting doors. The pivoting doors provide an easy access to the inside of the fan and facilitate its maintenance. On the inlet and on the outlet, the fan is provided with assembly flanges with rubber gaskets.

Electric motor

Asynchronous, three-phase 220-240/380-420V, 50Hz or single-phase 220-240V, 50Hz with a capacitor. The motors are made in accordance with IEC IEC60072 and IEC IEC60034 standards, and have been awarded with a CE mark. Insulation class F, degree of protection IP55.

On request, we can deliver motors driven by another voltage or frequency, with an increased degree of protection, adapted for voltage control or for a frequency converter, provided with an independent cooling system and/or with sensors (either bimetallic or posistor).
