Description Stihl KOA 20 Cordless Air Compressor – Portable AS-System Inflator The Stihl KOA 20 is a compact, battery-powered air compressor designed for the AS battery system. Perfect for both home and professional use, it allows quick and convenient inflation and deflation of tyres, air beds, sports balls, and more. Its rugged yet lightweight design, combined with smart features, delivers unmatched portability and performance. High-Performance Inflation and Deflation Equipped with a high-pressure pump, the KOA 20 reaches a maximum pressure of 10.3 bar (150 psi). A dedicated volume mode enables rapid inflation or deflation of larger items, adapting seamlessly to a wide range of tasks. Smart Digital Control The intuitive HMI display lets you select between pressure or volume mode, set a target pressure, and monitor battery status. It even compensates for altitude changes, ensuring accurate inflation wherever you are. Built-In LED Light & Convenient Storage An integrated LED light provides visibility in low-light conditions, while onboard storage keeps the hose and nozzles neatly organised. The hanging eyelet allows safe storage, keeping the compressor out of the way when not in use. Compact and Durable Design Weighing just 1.5 kg (tool only), the KOA 20 is highly portable. Rubber feet provide stability during operation, and its IPX4-rated housing ensures splash and workshop resistance for reliable, long-lasting use. Reliable AS Battery Performance Powered by the 10.8 V AS 2 battery (sold separately), the compressor maintains consistent power throughout the charge. A full battery provides approximately 23 minutes of runtime, sufficient for multiple inflations in a single session.
