Application

The LFA fans is designed for use in various mechanical ventilation systems. Exemplary applications comprise pressure and exhaust ventilation in individual ventilation and air conditioning systems. They are commonly used in cooling and drying systems, local exhaust facilities, ventilation of shops in various industries, etc.

Construction

A radial, low-pressure, directly-driven fan, designed for ventilation of rooms where the level of dust is low. The welded rotor, provided with forward-tilted blades is made of galvanized steel sheet. The rotor and the motor are dynamically balanced according to the standard ISO 1940. Housing is made of aluminum alloy and combined with the stand of the electric motor.

The whole set is painted with powder paint. The fans are designed for transporting non-aggressive and non-explosive, dust-free gases. As a standard, the LFA fans are manufactured in a LG 270 configuration with a protective mesh at the inlet.

On customer’s request, the equipment may be supplied in any RD configuration and in any color from the RAL palette (standard colors are RAL 5010 (blue) for sizes 108-250 and RAL 7042 (gray) for the size 250).

Electric motor

Asynchronous, three-phase 230/400V or 400V, 50Hz, or single-phase 230V, 50Hz, with a capacitor.
The motors are manufactured in accordance with IEC 60072 and IEC 60034 standards, and have been awarded with a CE mark. Insulation class F; degree of protection IP 55.

At request, we can deliver motors driven by another voltage or frequency, adapted for voltage control or for a frequency converter, provided with an independent cooling system, with sensors (either bimetallic or posistor) and multiple-speed.
