Super-powerful typhoon-level high-efficiency blower, compact and lightweight, wirelessly portable. Multi-functional, suitable for large-area high-efficiency blowing operations such as construction site sweeping, yard leaf removal, parking lot dusting, factory floor drying, and snow removal.

Product Parameters

Product Advantages

Three speed settings: Low speed 12000r/min is suitable for lightly blowing away desktop dust and cleaning computer dust; medium speed 15000r/min is used for dust removal on workshop floors; high speed 19000r/min has super strong airflow and can blow away wet leaves, gravel, and snow. The speed is adjusted by a lever, with clear speed settings.

Turbocharging technology: By optimizing the air duct and impeller design, the airflow is accelerated, generating a wind speed of 59 m/s (about 212 km/h) at a speed of 19, 000 r/min, which is equivalent to a strong typhoon and can blow away bricks and sandbags.

Brushless motor: No carbon brush wear, long lifespan, high efficiency, and over 30% longer battery life compared to brushed models with the same battery capacity. The motor operates with low noise, even at full speed, lower than traditional gasoline blowers.

13.2m³/min large flow rate: Blows out 13.2 cubic meters of air per minute, equivalent to replacing all the air in a small room in 1 second, making it extremely efficient for large-area cleaning.

Lightweight design: The overall weight of the machine is about 1.8-2.0kg (including battery), which is more than 50% lighter than gasoline blowers, and can be operated with one hand without pressure.

Ergonomic handle: The rear handle is rubber-coated, and the front auxiliary handle provides a comfortable grip, ensuring stable operation with both hands. The center of gravity is positioned towards the rear, reducing fatigue from prolonged lifting.

Product Comparison

FAQ

Q: What is the difference between a Li-ion brushless air blower and a regular blower?

A: The blower's airflow and speed far exceed ordinary blowers (ordinary approximately 2-5 m³/min, blower 13.2 m³/min). The blower can blow away wet leaves, pebbles, and snow, while ordinary blowers can only blow dust off tabletops.

Q: How long can the battery last continuously?

A: 4.0Ah battery, high speed (19000 rpm) provides approximately 15-20 minutes of continuous use; medium and low speeds provide 30-40 minutes. It is recommended to carry extra batteries or use 6.0Ah batteries. Two batteries and one charger are included for alternating use.

Q: Can it be used to blow snow?

A: Yes. A blower with a wind speed of 59 m/s is sufficient to blow away loose snow (5-10 cm thick). However, it has limited effect on compacted snow or ice.

Q: How to maintain?

A: Clean the air inlet filter after each use (to prevent debris from being sucked in); check the battery contacts; store in a dry place. The brushless motor requires no maintenance, but dust may accumulate in the air duct; it can be backflushed with compressed air.
