Explosion proof cooling fan for low-noise transformer fan box transformer main transformer定制

1、 Model meaning (DBF2-5Q8)

• DBF2Second generation low-noise transformer specific axial fan (DBF=low-noise transformer fan, 2=second generation)

• 5: Impeller diameter500mm

• Q：Front blowing type(Airflow blows from the motor through the impeller towards the radiator)

• 8：8-pole motor(Speed of about 720r/min, low speed and low noise)

2、 Structure

• impellerAluminum alloy wing shaped blades (4 pieces, can also be 5 pieces, 6 pieces), dynamic balance G2.5 level, rust proof, low noise

• motorThree phase asynchronous outdoor dedicated,IP55 protection, F-class insulationBuilt in 110 ℃ thermistor overheat protection

• hair dryerSteel plate rolling forming, flange/bracket installation, distribution line bracket, protective net

• transmissionDirect connection without belt, maintenance free

• InstallTwo methods: side blowing (radiator side) and bottom blowing (radiator bottom up)

3、 Performance parameters

• impeller diameter：500mm

• air volume：5550 m³/h、6240m³/h

• total pressure：56 Pa、100Pa

• speedApproximately 720 r/min (8 poles)

• power：0.25 kW

• Voltage/Frequency380V/50Hz (customizable)

• rated current：1.06 A

• noise: 55-60 dB (A) (5-10dB lower than normal BF)

• ambient temperature：-30℃～+50℃

• Protection levelIP55 (rainproof, dustproof, splash proof)

• insulation classF level

4、 Core advantages

1. Ultra low noise8 extremely low speeds+low-noise bearings+wing blade shape, suitable for substations and residential areas

2. Outdoor DurableIP55+F-grade insulation, suitable for humidity, sand and dust, high and low temperatures

3. Efficient coolingFront blowing direct blowing radiator, high heat exchange efficiency, fast cooling under heavy load

4. Reliable maintenance freeDirect connection without vulnerable parts, long bearing life, built-in overheating protection

5. Flexible installationSide blowing/bottom blowing optional, flange/bracket universal

5、 Application

• Electricity: Substation main transformer, power plant step-up transformer, industrial rectifier transformer, reactor cooling

• Scenario: Forced heat dissipation during high temperature/heavy load operation in summer, controlling oil temperature and protecting insulation

• Alternative: Ordinary BF series, more suitable for outdoor and low-noise places with high requirements

6、 Common models

• DBF2-5Q8THDamp heat zone type (anti-corrosion, moisture-proof)

• DBF2-5Q8-EXExplosion proof type (for use in explosion-proof areas)

• DBF2-5Q8 can also be made of stainless steel or fiberglassOutdoor reinforced type (more corrosion-resistant)
