Motor and airflow
The brushless motor reaches a no-load speed of up to 38,000 rpm. Unlike a brushed motor, it has no brushes that wear down during operation, which may reduce maintenance needs.
Maximum air speed is approximately 55 m/s, or 198 km/h. Airflow reaches up to 606 m³/h. Air speed describes how fast the air moves, while airflow describes the volume of air moved over a given time. Both figures are useful when clearing leaves from a larger area.
The specifications also list a maximum “wind pressure” of 1500 G. The meaning of G in this figure is unclear, so it cannot be reliably compared with pressure expressed in conventional units or used to determine blowing force.
Five speed settings
The Foursun LB01 offers five speed settings. A lower setting provides gentler airflow, while a higher setting is useful when a stronger stream of air is needed. This lets you adjust the blower for tasks such as cleaning a workshop or clearing leaves in the garden.
Take care when working near electronics: switch the electronic device off first and adjust the airflow for sensitive components. The blower is not an air purifier; it is intended to blow debris off surfaces and out of places the airflow can reach.
Battery and runtime
The blower uses a 4.0 Ah Li-ion battery. Its stated runtime is up to 120 minutes on a single charge, but the available figure does not specify the speed setting or other measurement conditions. Actual runtime may therefore vary depending on the setting and conditions.
The model is offered in configurations with one or two batteries. A second battery provides a spare to swap in while working; the number of batteries in the package does not itself mean they are used simultaneously.
Dimensions and handling
Without the tube attached, the blower body measures approximately 280 mm. With the tube, its length is approximately 660 mm. The shorter body is easier to carry, while the tube helps direct airflow towards more distant spots.
The LB01 combines adjustable airflow with cordless power and dimensions suited to handheld use. When considering runtime, treat the stated 120 minutes as a maximum for which the test conditions have not been specified.
