Cordless 110,000 RPM Air Blower
The Rosewill WT009-BLACK is a centrifugal blower driven by a brushless motor that spins up to 110,000 RPM. Four adjustable gears let users match airflow to the task, from delicate sensor cleaning to heavy debris removal. Its cordless design and 0.53 IBS weight make it practical for field technicians, PC builders and anyone who needs portable dust removal without disposable cans.
Sustained Run-Time and Recharge Cycle
A 4000 mAh battery delivers 60 to 80 minutes of continuous operation depending on the selected gear. USB-C charging restores full capacity in roughly 4 hours using a 5 V, 2 A adapter. The motor stops automatically when the charge drops below 5 %, indicated by a flashing light that signals the need to recharge before the next session.
Gear 4 Instant Burst for Stubborn Debris
Holding the oval nozzle button activates maximum airflow instantly, regardless of the current gear setting. This single control bypasses the normal cycle and targets the toughest dust in seconds. Buyers who need variable airflow without a boost function or who prefer a tethered compressed-air supply will not find those options here.

Questions about this item
How loud and hot does the 110,000 RPM brushless motor get during extended use?
The brushless motor runs efficiently at up to 110,000 RPM with four selectable gears. Lower gears produce less noise and heat, while Gear 4 delivers maximum airflow for short bursts.
What charging equipment must I already own to recharge the 4000mAh battery?
