Robust and powerful cordless air brush for cleaning workstations, tools, and assembly vehicles, as well as for blowing out wall joints, drill holes, and more. It offers very effective efficiency due to its high airspeed and correspondingly efficient air throughput. The 3-stage switch with electronic airspeed control allows for material and environment-specific use. Perfect handling is ensured by its compact and lightweight design, along with ergonomically rubberized grip areas. It features a safety switch with a locking mechanism for trouble-free continuous operation. The air brush is expandable and can be used with standard accessories such as a 220 mm blowing tube, a 214 mm blowing tube extension, and an adapter for inflating objects or for suctioning air out of objects. It is compatible with any 18.0 Volt Li-Ion XR battery of all Ah classes. The standard version does not include batteries or a charger, making it an optimal addition to existing XR 18 Volt batteries.
