The Einhell Compressor Pressito 18/21 is an all-rounder in the home, workshop and garage. As a member of the Power X-Change family, all batteries in the system family can be used. An 18 V battery is required for operation. Can be used as a high-pressure and low-pressure pump, and for deflation. The desired pressure can be set with the high-pressure pump. When this pressure is reached, the compressor switches off automatically. Practical features are the manual operation digital pressure display (selectable units: bar, psi, kPa) and a pushbutton switch for inflating with high pressure without pressure presetting. The storage compartment for the 3-piece adapter set is practical. Delivery does not include battery or charger (sold separately).
