Air tools are generally lighter and more powerful than their electric cousins, but if you’re using an electric compressor, you still need a source of electricity. With gas-powered air compressors you’re truly free of the plug. While they’re not a new concept, DeWalt has added a couple new models that you might want to consider.
The two compressors really only differ in their capacity and number of wheels. The D55690’s dual tanks have an eight-gallon capacity, and a 10″ semi-pneumatic wheel mounted between the tanks gives the compressor more mobility, while the D55695 uses a more traditional-looking 17-gallon tank perched upon two of the same 10″ wheels.
Driven by a 270cc, 9 HP OHV engine, both compressors output 150 Max PSI and 16.3 SCFM @ 100 PSI. DeWalt achieves these pressure and flow ratings with a four-cylinder cast iron pump. The engine features an automatic idle control for reducing fuel consumption, and it’ll shut off when the oil’s low to protect the pump. Finally, a ball drain valve allows you to quickly drain the tank.
The compressors take an 18V XRP battery to start the engine — they both ship with the battery and a 1-hour charger. The D55690 runs $1,600 to $2,000, and the D55696 is about $100 more at $1,700 to $2,100.
