The BOSS Bullet G 70 delivers 70 CFM of continuous rotary screw compressed air from a Kohler V-Twin engine in a package you can mount anywhere — skid, wheel, or truck bed. With class-leading fuel efficiency, the Bullet G 70 is the most versatile portable gas rotary screw compressor in the industry. Built to BOSS quality standards with a 2-year Kohler engine warranty.
Freight: Ships by truck freight, flat $425 to the contiguous US.
The Boss Bullet features make this engine the most fuel efficient, quiet running, and maintenance free in its class. It is available as either a skid mounted unit or wheel mounted.
For higher altitude environments (5,000′ above sea level or higher), we offer an E.F.I. engine package that ensures proper performance. This is highly recommended when working in varying altitudes.
