The LFB fans is designed for use in various mechanical ventilation systems. They are designed for ventilation of rooms where the level of dust is low. 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. They perform well in air filtration systems, e.g. in exhaust systems in paint shops, spray booths, etc.
A radial, low-pressure, directly driven fan. The welded rotor, provided with forward-tilted blades is made of galvanized steel sheet. The rotors are dynamically balanced according to the standard ISO 1940. Housing is made of welded steel sheet, reinforced with steel angle bars and connected to the base 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 LFB fans are manufactured in a LG configuration with a protective mesh at the inlet.
On request, we can supply the equipment in any RD configuration and in any color from the RAL palette (RAL 5010 - blue is the standard color).
