HPB-F 200Hz

APPLICATION

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

Typical uses:

• pneumatic transport systems
• blowing in drying systems (e.g. graphic machines and plastics processing)
• air blowing systems in combustion / thermal treatment systems (e.g. melting furnaces)

CONSTRUCTION

• high-pressure centrifugal fan with direct drive
• riveted impeller made of aluminum sheet, with B-type blades, dynamically balanced according to ISO 1940-1
• die-cast aluminum housing
• galvanized inlet cover
• base welded from steel sheet
• fan painted gray RAL7042 (in selected sizes motor painted RAL 5010)
• maximum temperature of the transported medium 80°C
• figure LG270

MOTOR

• asynchronous, three-phase, 230/400V, 100Hz or 400V, 100Hz (depending on the motor power)
• insulation class F
• degree of protection IP55
• equipped with thermal protection PTC or PTC and TP depending on the model
• FC version equipped with an independent cooling module
• motor ambient temperature from -20°C to + 40°C

MOTOR CONVERTER

The converter supplying the motor must have the following U(f) classification:

where: U - rated voltage of the motor operation; f - frequency 200Hz

If the recommendations are not followed, the motor current increases disproportionately and the motor does not reach the rated speed. Under no circumstances should the frequency (rotational speed) be set higher than the 200Hz frequency stated on the nameplate, because the motor may be overloaded or the blower damaged due to too high speed.

The so-called boost, as this causes the drive motor to heat up too much. In order to protect the motor, a temperature sensor must be connected to the appropriate inputs of the converter.
