Portable high-pressure inflation for automotive and site equipment
The Milwaukee M12 BI-401 Sub Compact Inflator is engineered for rapid and controlled inflation of car tyres, light truck tyres, and compact equipment. Powered by the M12 platform, the unit integrates a high-efficiency motor and pump system capable of delivering up to 8.27 bar (120 PSI), making it suitable for workshop, fleet, and service vehicle applications.
An illuminated LCD display provides digital pressure readout and remaining battery status, while the integrated auto shut-off function inflates to the user’s pre-selected pressure for accurate and repeatable results. The 660 mm hose with all-brass Schrader chuck, combined with onboard nozzle storage, ensures practical field usability and reduced setup time.
