Versatile Inflation and Deflation
The STIHL KOA 20 is a battery-powered air compressor designed for a wide array of jobs in your home or workshop. This versatile 2-in-1 unit simplifies inflation and deflation tasks, powered by the reliable 10.8V STIHL AS 2 battery. It is perfectly suited for inflating tyres on vehicles, ride-on mowers, and bicycles, as well as everyday items like air beds, footballs, and pool accessories. The deflation function also allows for the quick packing away of items like pool inflatables.
The KOA 20 comes equipped with various attachments and nozzles, all of which can be conveniently stored on the tool itself, ensuring they are always ready for use. A high-quality brass nozzle on the hose allows for fast and secure connections. Please be aware that the KOA 20 is not designed for use with compressed air tools or for inflating high-pressure items like paddle boards.
Intelligent Design and Control
Engineered for user comfort and efficiency, the compressor features an ergonomic design with a soft-grip handle and stable rubber feet to prevent movement during operation. An integrated LED light at the front of the tool provides excellent illumination for working in poorly lit areas. The easy-to-read digital display and control panel allow for straightforward operation. Users can switch between high-pressure and high-volume functions with the MODE button, set the precise target pressure with the plus and minus buttons, and cycle through pressure units (BAR, PSI, kPA) with the UNIT button, which also activates the LED light.
STIHL AS Battery System Performance
As part of the STIHL AS System, the KOA 20 benefits from intelligent electronics that deliver constant power, ensuring performance does not decrease as the battery discharges. This set includes the recommended AS 2 battery and AL 1 standard charger, providing a solid foundation for any user.
| Battery Model | Run Time | Charge Time (AL 1 Charger) |
|---|---|---|
| AS 2 (Included) | Up to 23 mins | 80 mins (to 100%) |
