DEWALT 30-Gallon Vertical Portable 175 PSI Air Compressor

High-Pressure Performance, Extended Tool Runtime & Job-Site Portability

The DEWALT 30-Gallon Vertical Portable Air Compressor is engineered for demanding workshop and job-site applications, delivering up to 175 PSI maximum working pressure and 6.2 SCFM at 90 PSI. Its high-capacity vertical design provides extended air availability for pneumatic tools while maximizing usable workspace.

Compared with the referenced PORTER CABLE 30-Gallon 135 PSI air compressor, this DEWALT model delivers 30% higher maximum PSI, 29% higher SCFM air delivery, 2.5× longer air-tool runtime, and 23% quieter operation. A high-flow regulator further increases usable air pressure delivered to the connected tool.
