HB

APPLICATION

HB fans are designed for transporting clean air. t has many applications in industry, where  in technological processes need a small airflow and high pressure. Typical applications:

• supplying air to gas burner systems,
• filtration systems,
• air transport,
• air drying systems,
• cooling systems.

CONSTRUCTION

• high and very high-pressure, direct drive, radial fan,
• steel sheet rotor with backward inclined blades,
• steel welded housing,
• painted RAL 5010 (blue), corrosivity category C3,
• medium maximum temperature 80°C,
• ambient temperature of the motor from -30°C to 60°C  (depending on model - see technical characteristic table),
• depending on the motor power, the fans are standard in two figures LG90 and LG270 (see specifications table),
• Fans are standard in LG270 configuration.

MOTOR

• asynchronous, three-phase 230V/400V 50Hz or 400/690V 50Hz, efficiency class IE3
• degree of protection IP55,
• insulation class F,
• three-phase motors are adapted for frequency converter.

SPECIAL EXECUTIONS

• optionol configuration LG/RD,
• color other than standard and higher category of corrosivity,
• housing and support made of galvanized steel sheet, stainless steel 1.4301, acid-proof steel 1.4404,
• motor with voltage and frequency of power, degree of protection different than standard,  equipped with sensors or additional cooling,
• sealing between the housing and the motor,
• HT version - maximum transported medium temperature higher than standard,
• ambient temperature range below -20°C and above 40°C,
• belt drive, clutch,
• ATEX version
