It looks like you're referencing a 2 kW (kilowatt) fan used in a sweeper truck (often called a street sweeper or road sweeper).

Here is a breakdown of what that specification means, its typical applications, and key considerations.

What does a 2.2 kW fan do in a sweeper truck?

In a sweeper truck, the main engine (often a diesel engine) powers the vehicle movement, and a secondary engine or a PTO (Power Take-Off) powers the hydraulic system. This hydraulic system drives the main fan.

• The Fan's Role: The fan creates the vacuum or airflow needed to suck debris (dust, leaves, gravel) from the road into the hopper (the collection bin). It's the core component of the "sweeping" action.
• 2 kW Power: 2.2 kW is approximately 3 horsepower (hp) . This is a relatively modest power rating for an industrial sweeper fan.
  • Comparison: Small, walk-behind sweepers might use 1-2 kW.
  • Large Truck-Mounted Sweepers: Often use fans with motor ratings of 15 kW, 30 kW, or even higher (20-40+ hp) for heavy-duty highway or industrial use.

Key Applications for a 2.2 kW Sweeper Fan

Given its power level, this fan is most likely found in:

1. Compact Sweepers: Small truck-mounted sweepers (e.g., on a pickup chassis) or tractor-mounted sweepers.
2. Pedestrian / Walk-Behind Sweepers: Larger, industrial-grade walk-behind machines. A 2.2 kW motor provides strong suction for a machine of that size.
3. Electric Sweepers: Many modern, environmentally-friendly sweepers use electric motors. A 2.2 kW electric fan motor is common for smaller, emission-free models used in indoor spaces (warehouses, airports, factories) or pedestrian zones.

Important Considerations for a 2.2 kW Sweeper Fan

If you are specifying, repairing, or replacing this fan, here are the critical technical points:

• Voltage & Current (Crucial for Electric Fans):
  • 230V AC: ~9.6 Amps.
  • 400V AC (3-Phase): ~3.9 Amps. (Most common for industrial sweepers).
  • 48V DC: ~46 Amps. (Common for hybrid or electric sweepers). Wiring must be heavy gauge for DC.
• Airflow (CFM/m³/h): The power doesn't directly tell you the airflow. A 2.2 kW fan can move a very high volume of air at low pressure (like a big, inefficient dust collector) or a moderate volume at high pressure (like a centrifugal fan for a sweeper). Look for the fan curve to match pressure and flow.
• Type of Fan: Almost always a Centrifugal Fan (often called a "squirrel cage" blower) rather than an axial fan (like a desk fan). Centrifugal fans are better at generating the high pressure needed for suction.
• Duty Cycle: Industrial sweepers run for hours. The motor must be rated for continuous duty (S1) .
• Housing Material: The fan housing must be robust. Cast iron or fabricated steel are common to handle debris impacts.

Common Problems with a Sweeper Truck Fan

1. Blockage: Debris gets sucked into the fan inlet, jamming the impeller. This often causes the motor to trip the breaker or blow a fuse (thermal overload).
2. Belt Drive Issues: Many fans are belt-driven from a hydraulic motor or PTO. A 2.2 kW load on a belt drive can cause belt slipping, wear, or breakage if not tensioned correctly.
3. Bearing Failure: The fan motor bearings (or separate fan shaft bearings in a belt-driven setup) are subjected to dust and vibration. They are a common maintenance item.

In Summary

If you have a specific issue (e.g., "My 2.2 kW sweeper fan motor is overheating" or "I need to find a replacement fan for a sweeper truck model X"), please provide more details, and I can give you more targeted advice.
