It seems like you're looking for specifications or information about a 1 kW (kilowatt) shredder blower, often used for garden waste (leaf vacuums/mulchers) or industrial wood chip/shredding systems.
Here is the typical breakdown of what a 1 kW (approx. 1.5 HP) shredder blower unit looks like and how it performs:
Typical Applications
- Garden Leaf Vacuums: Corded electric blowers that suck up leaves, shred them, and blow the mulch into a bag.
- Small Wood Chipper/Shredders: Entry-level electric chippers for twigs and soft vegetation.
- Industrial Dust Extraction: Small extraction units for CNC routers or woodworking shops (though 1.1kW is on the low side for that).
Performance Specifications (Typical)
| Specification | Expected Value |
|---|---|
| Power | 1 kW (1.5 HP) |
| Cutting Mechanism | Impeller with hardened steel blades (flails) |
| Reduction Ratio | 10:1 to 16:1 (reduces 10 bags of leaves to 1 bag) |
| Max Branch Thickness | 25 mm – 35 mm (1 – 1.4 inches) |
| Vacuum Speed | 6,000 – 8,000 RPM (typical for electric motors in this range) |
| Volume Capacity | 2,500 – 3,000 m³/h (airflow) depending on impeller design |
| Noise Level | 90 – 100 dB (requires hearing protection) |
Common Features
- Metal Impeller: Essential for longevity; plastic impellers break quickly with wet leaves.
- Anti-Clog System: Many models have a reverse switch or anti-jam feature (pressing the safety stop button reverses the impeller).
- Collection Bag: Usually 30L – 50L integrated or an attachment.
- Overload Cutout: A thermal switch that kills power if the motor overheats (as it often does with wet, heavy shredding).
Important Caveats for 1.1 kW Units
- Not for heavy wood: A 1.1kW motor can handle dry twigs up to ~25mm, but it will struggle (and likely jam or burn out) with wet wood, green branches, or anything harder than pine.
- Cord is required: This is a corded unit. You will lose power/draw with a long extension cord.
Choosing a 1.1 kW Model
If you are evaluating a specific machine, look for:
- Max RPM: Higher is better for shredding leaves.
- Blade Material: Look for hardened (tempered) steel blades.
- Warranty: 2-3 years is standard for European/Asian manufacturers.
Is this related to something specific?
Are you trying to:
- Fix a machine (e.g., why it won't start)?
- Upgrade the motor?
- Match this to a dust extraction system?
- Assess if it can handle a specific type of wood (e.g., oak, willow)?
Please let me know if you have a specific model in mind (e.g., Einhell GH-HE 1845, Ryobi RBL30MV, Black+Decker GW3030), or if you need help calculating the airflow requirements for a ductwork system. I can give you exact numbers for a specific unit.
