DeWalt introduces three new heavy-duty electric-wheeled portable compressors — the D55171 (pictured), D55371 and D55394 — that feature sealed-lube or low-oil consumption pump technology for increased durability. The 1.6-hp D55171 and D55371 compressors operate at 175 psi and 4.6 scfm at 100 psi, and have an operational noise level of 74 dBA, which creates a quieter work environment. The D55171 is designed with start/stop operation, while the D55371 and D55394 use a dual control feature that allows users to easily start, stop or consistently run the unit. The compressors also feature puncture-resistant 12-inch semi-pneumatic tires.
