DeWalt launched its heavy-duty electric-wheeled portable compressors (D55171, D55371, D55394) in 2008. DeWalt built these units with a new Sealed Lube or low oil consumption pump technology for increased durability. Additionally, each unit has been designed and factory set with higher max tank PSI to provide users with the surge air power and recovery needed to run more nailers. The compressors are ideal for multiple applications, including framing, roofing, remodelling, deck building and trim carpentry.
