It seems you are looking for information on a 5 kW sweeper blower. This is a high-power industrial component typically used in street sweepers, large warehouse cleaners, or heavy-duty vacuum systems.

Here is a breakdown of what a 5.5 kW (approx. 7.4 HP) blower means for a sweeper, common specifications, and typical applications.

Key Meanings & Specifications

1. Power Output: 5.5 kW.

   • Comparison: This is significantly more powerful than a standard shop vac (1.2-2.2 kW). It is equivalent to the power of a large central vacuum system or a small industrial dust collector.
   • Voltage: In industrial settings, this blower will almost certainly be 3-phase (e.g., 380V, 400V, or 415V). A single-phase 5.5 kW motor is very rare and would require a very high amperage circuit (e.g., 230V ~24 Amps).

2. Airflow (CFM/m³/h):

   • A 5.5 kW regenerative or centrifugal blower will typically move 600 to 1,200 CFM (cubic feet per minute) or approximately 1,000 to 2,000 m³/h depending on the impeller design and pressure.

3. Pressure (Static Pressure):

   • These blowers are designed for high static pressure to move debris through long hoses or heavy filter systems. Expect a pressure rating of 2,000 to 3,000 Pa (or 8 to 12 inches of water gauge).

Common Applications for a 5.5 kW Sweeper Blower

This motor size is generally too large for a small walk-behind lawn sweeper but is the standard size for:

• Truck-mounted street sweepers: Used for the main suction intake where debris is sucked up from the road.
• Industrial ride-on sweepers: Large cleaning machines in factories, warehouses, or parking garages.
• High-volume dust extractors: Used on concrete cutting or demolition sweepers.
• Grain or material handling: Moving light bulk materials.

How to Choose / Important Parameters

If you are looking to buy or replace this blower, you cannot just match the kW. You must match the Performance Curve to your machine. Here are the three most important questions:

Type of Impeller?

• Regenerative (Side Channel): Provides high pressure at relatively low airflow. Good for lifting debris through a suction pipe. (Most common in sweepers for suction).
• Centrifugal (Radial/Backward Curved): Provides higher airflow at medium pressure. Good for pushing air through a filter system.

Rotational Speed (RPM)?

• Direct Drive vs. Belt Drive: A 5.5 kW motor might run at 2,900 RPM (2-pole) or 1,450 RPM (4-pole). Belt drives allow you to change the speed to tune the pressure vs. airflow.

Inlet Size?

• Standard industrial inlets for this power range are usually DN100 (4″) , DN125 (5″) , or DN150 (6″) .

Example Brands

If you are researching a specific model, common manufacturers include:

• AMETEK (Lamb Electric)
• Elektror
• FPZ
• Busch
• Gardner Denver
• Vortice (Industrial line)

Safety Note

A 5.5 kW 3-phase motor requires specialized wiring and a proper motor starter (contactor/overload relay) or a Variable Frequency Drive (VFD). It cannot simply be plugged into a standard wall outlet.

If you can provide more context (e.g., "I need one for a Tennant sweeper" or "I want to build a DIY system"), I can give more specific advice.
