LFA

Application

The fan is designed for transport systems of non-aggressive and non-explosive gases without pollution. Typical uses are:

• supply / exhaust in individual ventilation and air conditioning systems,
• cooling and drying systems,
• ventilation of workshops.

Construction

• low-pressure radial fan with direct drive
• impeller welded from steel sheet with forward curved blades, dynamically balanced according to ISO 1940-1
• casing made of aluminum alloy
• galvanized protective mesh at the inlet
• fan stand in models 160A, 180-225
• motor stand in the 250 model
• fan painted gray RAL 7042
• maximum temperature of the transported medium 80°C
• motor ambient temperature from -20°C to +40°C
• figure LG270

Motor

• asynchronous, single-phase, 230V 50Hz (power up to 1,5kW)
• asynchronous, three-phase, 230/400V 50Hz (power up to 3kW)
• asynchronous, three-phase, 400/690V 50Hz (power from 4kW)
• degree of protection IP55
• insulation class F
• for frequency control (three-phase motors)

Special Executions

• any LG / RD figure
• painting in a color other than the standard
• motor for voltage and frequency other than standard
• motor with different IP protection class
• motor equipped with sensors or additional cooling
• sealing between the housing and the motor (simmering)
• motor ambient temperature below -20°C and above +40°C
