The D55146 includes:

  • 1x DeWalt D55146 Heavy-Duty 200 PSI 4.5 Gallon Electric Wheeled Portable Compressor


  • 200 PSI max tank storage pressure provides a user with 80% more usable air than the industry leader
  • 5.0 SCFM @ 90 PSI allows the compressor to recover quickly after its initial tank charge is exhausted
  • Vertical stand feature and collapsible handle allows a user to save space by transporting or storing the compressor in a vertical position
  • 78 dBA* operational noise level for a quieter work environment (* tested per ISO3477)
  • 10" non-flat foam tires allow for easy transportation around the jobsite
  • EHPEfficient high pressure technology allows for longer pump and motor life
  • Oil free, maintenance free pump for convenient use

There are some companies that specialize in air compressors. They eat, sleep, and breathe air compressors. And yet companies like that can't match the amount of usable air that DeWalt's D55146 Electric Wheeled Portable Compressor can put out. It can operate at 200 PSI, delivering an excess of 80% more usable air than similar models by the industry's leader. After the initial tank load is used up, its 5 SCFM at 90 PSI allows for a speedy recovery. You'd think that a compressor this powerful would make more noise than a baby who found some pots and pans. Au contraire, this compressor operates at just 78 dB. DeWalt's exclusive Efficient High Pressure Technology (EHP) increases the longevity of both pump and motor. Would you prefer it be stored standing up or laying down? You have the option to choose with the D55146. Its oil free pump doesn't require regular maintenance (or any at all, for that matter). The metal console panel not only protects the gauges, couplers, and regulators, but it also provides a great surface for displaying legible readings. Lastly, the compressor's 1.6 HP motor can also be run with an extension cord, allowing the consistent draw requirements to be met. The industry's leader easily wins when it comes to the huge compressors in your shop, but when you need compressed air on the go, DeWalt's D55146 is your best bet.


  • Efficient high pressure motor allows the compressor to be run with an extension cord (12 Ga. or heavier, 50 ft. or less) due to consistent amp draw requirement of the compressor
  • High flow coupler allows for maximum nailer performance
  • Metal console panel provides a display area as well as protects the gauges, couplers, and regulator
  • High flow coupler allows for maximum nailer performance
  • 2 inch gauges allow for an easy to read surface
