The STIHL KOA 20 is a powerful battery-powered air compressor designed for a wide range of jobs around the home or workshop. This versatile 2-in-1 unit makes both inflation and deflation quick and convenient, powered by the efficient 10.8 V AS 2 battery. It is the ideal tool for inflating tyres on vehicles, ride-on mowers, and bicycles, or for managing leisure items like air beds, footballs, and pool accessories. The deflation function also allows for the rapid packing away of items like pool inflatables.
This model is supplied as a tool-only unit, without a battery or charger, allowing you to expand an existing STIHL AS System tool collection. It comes with various attachments and nozzles that are conveniently stored directly on the tool, ensuring they are always to hand when needed. Please note, the KOA 20 has not been designed for use with compressed air tools or for inflating high-pressure items like paddle boards.
Operating the KOA 20 is straightforward thanks to its clear, top-facing digital display and control panel. A simple press of the MODE button allows you to switch between the high-pressure function for tyres and the high-volume function for inflatables. Using the plus and minus buttons, you can preset the desired target pressure, and the compressor will automatically stop once it’s reached. The UNIT button lets you cycle the pressure reading between BAR, PSI, or kPA to suit your needs.
STIHL has designed the KOA 20 with user convenience in mind. It features an ergonomic design with a soft-grip handle for comfortable use and rubber feet for stability during operation. An integrated LED light, activated via the control panel, illuminates the work area in low-light situations. The compressor also includes a high-quality brass nozzle on the hose for fast and secure connections. Thanks to STIHL’s intelligent electronics, the tool delivers constant power, ensuring performance doesn’t decrease as the battery discharges. For easy and safe storage, a practical hanging eyelet is built into the tool’s body.
