What Is a Li-ion Blower?

A Li-ion blower is a portable pneumatic tool that uses a lithium battery to drive a motor, spinning a fan at high speed to accelerate air and eject it in a concentrated stream from a nozzle. It is commonly used for blowing dust, leaves, and water, as well as for vacuum cleaning. Unlike corded blowers, Li-ion blowers are completely free from the constraints of power cords and can be used freely outdoors, at heights, and in areas without electricity.

The BOSI Li-ion blower series is divided into two technological tiers: the Rechargeable hair dryer is powered by a 20V/4.0Ah battery driving a 16,000 rpm motor, delivering an air volume of 0–2.3 m³/min and an air speed of 96 m/s. It has a two-in-one blow-and-vacuum function, capable of both blowing dust and collecting debris.

The Li-ion Brushless air conditioner is equipped with a brushless motor and turbocharging technology, with three adjustable speed settings of 12,000/15,000/19,000 r/min, a maximum air volume of 13.2 m³/min, and a maximum air speed of 59 m/s.

An innovative air duct concentrates the wind output, and the multi-purpose design covers a wide range of wind power needs from light dust blowing to heavy-duty site clearing.

Applicable Cleaning Objects

BOSI Li-ion blowers, with their two-in-one blow-and-vacuum function, can handle a variety of cleaning objects across construction sites, gardens, and workshops:

1. Concrete Dust and Wood Chips

Surface dust on walls after slotting on construction sites, concrete dust on floors, and wood chips from carpentry saw tables.

The Li-ion Brushless air conditioner, with its large air volume of 13.2 m³/min and top speed of 19,000 r/min, can quickly blow and concentrate dust over large areas.

2. Leaves and Wet Grass Clippings

Leaves on garden lawns, wet grass clippings after trimming, and accumulated leaves in shrubbery. Both the medium and low settings of the Li-ion Brushless air conditioner and the Rechargeable hair dryer can handle these tasks.

The turbocharged airflow is concentrated, making it difficult for wet leaves to remain.

3. Dust in Equipment Crevices

Dust in automotive engine compartments, dust buildup on electrical cabinet heat sinks, and on the fins of outdoor air conditioner units.

The Rechargeable hair dryer has an air speed of up to 96 m/s, and its thin, long nozzle can reach deep into narrow crevices. The blow-and-vacuum function can also simultaneously collect loose dust.

4. Accumulated Water and Snow Particles

Residual water droplets on equipment surfaces and thin snow on steps. The large air volume of the Li-ion Brushless air conditioner quickly dries surface moisture, reducing the risk of rust.

5. Debris and Lightweight Waste

PVC pipe cutting chips, plastic packaging scraps, and paper shreds. The suction function of the Rechargeable hair dryer can collect debris into a dust bag, keeping the floor clean.

Our Li-ion Blowers vs. Other Brands: Why Choose BOSI?

BOSI Li-ion blowers are centered on brushless turbocharging and a two-in-one blow-and-vacuum design, paired with a high-capacity 20V battery platform, establishing a significant advantage over generic brands in portability and wind power output.

How to Choose the Right Li-ion Blower?

The primary criteria for selection are the work area and the object being cleaned. For narrow crevices, equipment dust removal, or when vacuum collection of debris is needed, choose the Rechargeable hair dryer; its high air speed of 96 m/s provides targeted and precise cleaning.

For large-area dust, leaves, or wet grass clippings, the Li-ion Brushless air conditioner is essential; its large air volume of 13.2 m³/min combined with turbocharging provides wide coverage and high efficiency.

Both models use the same 20V/4.0Ah battery platform, allowing batteries to be used interchangeably.
