ABAC AS-7.5501TM 7.5 HP Rotary Screw Air Compressor - 131 Gallon Tank Mount, 150 PSI, 27.1 CFM, 67 dBA

The ABAC AS-B 7.5 HP tank mount is a rotary screw air compressor built for shops that run air continuously rather than in bursts. It delivers 27.1 CFM at 150 PSI and runs at 67 dBA, quiet enough to sit in the work area instead of a separate compressor room. The compressor arrives already mounted on a 131 gallon air receiver, so it lands as a single package with no separate tank to source or plumb. The 150 PSI rating suits shops running tools or equipment that need pressure above a standard 125 PSI supply. Choose 230V single-phase (AS-7.5501TM) or 208-230-460V three-phase (AS-7.5503TM).

Typical applications

Automotive service bays, tire shops, small production and fabrication floors, cabinet and woodworking shops, and any operation where a piston compressor is cycling too hard to keep up. A rotary screw is built for continuous running, so it holds a steady line pressure through a full shift instead of recovering between jobs. The larger 131 gallon receiver gives more stored air than the 71 gallon build, which helps when a shop draws in heavy bursts, such as several service bays pulling on impact tools at once.

Part of the ABAC AS-B 5 to 20 HP screw range from the Atlas Copco group. The 150 PSI build trades a little air delivery for higher available pressure against the 125 PSI version of the same machine, and a dryer can be added downstream when air tools or finishing work need moisture control.
