D55140 Specifications, Features & Compatibility Guide

The engineering of the DeWalt D55140 centers on the efficiency of its 0.22 kW permanent magnet motor and belt-driven pump. By utilizing a 135 PSI maximum pressure rather than a standard 100 PSI, the 3.79 L tank effectively stores more compressed air, allowing for longer tool runtimes between motor cycles. The 0.75 SCFM at 90 PSI rating is specifically tuned for tools with low air consumption, such as 23-gauge pinners or 18-gauge brad nailers, preventing the motor from overworking. Its noise profile of 71–71.5 dB(A) is achieved through the belt-drive isolation, which reduces the vibration transferred to the steel tank. The 2.6 A current requirement is intentionally low to ensure the unit starts reliably in cold weather or when used with long extension cords common in residential trim carpentry. Furthermore, the 10.9 kg chassis includes a roll cage to protect the integrated pressure gauge and regulator from impact during transport.
