Why choose the STIHL KOA 20 cordless compressor?
The STIHL KOA 20 cordless compressor is a compact, battery-powered inflator designed for everyday jobs around the home, garage, workshop and campsite. It can inflate vehicle and bicycle tyres, sports balls, air beds, pool accessories and other compatible inflatables without requiring a mains connection.
This versatile 2-in-1 compressor has separate high-pressure and high-volume functions. Use the high-pressure mode for tyres and sports equipment, or switch to the high-volume mode to inflate or deflate larger low-pressure items such as air beds and inflatable toys.
The KOA 20 is powered by the compact STIHL AS 2 battery and is available from Masseys as either a tool-only machine or a complete kit with a battery and charger.
