Key Features
Honda Gas PowerThe 8 HP Honda 4-cycle engine gives this compressor true jobsite independence when electric power is not practical. Low oil shutdown helps protect the engine during long workdays. Built for Daily DutyA heavy-duty two-stage cast-iron twin-cylinder pump is made for serious air demand and long service life. Ball bearings, cast iron valve plates, and Swedish lamellar reed valves point to a compressor built for work, not light occasional use. Jobsite ControlAutomatic pilot valve operation, automatic idle control, an air-cooled aftercooler, and a flexible discharge hose help the Rolair gas powered compressor run more efficiently and more manageably in real working conditions.
Overview
The Rolair 7722HK28-0001 8HP Gas Powered Compressor is a professional gas powered air compressor built for crews that need serious compressed air away from fixed power. This is a compressor designed for jobsite air supply in locations where portability and engine-driven operation matter more than plugging into an outlet. Model Number: 7722HK28-0001.
At the center of this machine is a heavy-duty two-stage pump with cast-iron twin cylinders. That matters because cast iron handles heat and long runtimes better than lighter consumer-grade pump designs. Ball bearings, splash lubrication, cast iron valve plates, Swedish lamellar reed valves, aluminum alloy connecting rods with automotive-style inserts, and a large multi-finned 15.16 inch flywheel all point to a compressor that is built to keep working under steady air demand, not just cycle on for quick household tasks.
The engine side is just as important. Rolair pairs this unit with an 8 HP Honda 4-cycle engine built with a die cast aluminum alloy body and cast-iron sleeve. Overhead valves support reliable performance, while the retractable starter and on/off switch keep operation straightforward. Low oil shutdown is the kind of feature that pays for itself, because it helps prevent expensive damage if oil level drops during transport or extended use.
On a real jobsite, convenience features make a difference. This compressor includes automatic pilot valve operation and automatic idle control, which help manage engine operation for better economy and longer service life. The industrial flexible discharge hose gives you a durable connection point, while the intake filter with silencer and replaceable element helps protect internal components and cut down intake noise. The air-cooled aftercooler helps reduce discharge temperature, which is a practical advantage when you are running tools over longer periods.
Rolair also built in the protective details you want on a machine in this class. A totally enclosed steel belt guard helps shield moving parts, and the safety relief valve adds another layer of operating protection. The pressure gauge reads from 0 to 300 PSI in 5 pound graduations, which gives you clear visibility when dialing in air delivery for different pneumatic tools and applications.
At 280 lbs, this is not a small trim compressor and it is not pretending to be. It is a serious engine-driven air system for contractors who need higher output and a more durable pump package than a light portable unit can offer. If you are outfitting a crew for construction, service work, agricultural property maintenance, or remote-site use where electric power is limited, this Rolair compressor makes sense. If you only need to air up tires once in a while, this is far more machine than you need.

Pro Tip
With a compressor this size, the low oil shutdown is a real safeguard, but it is still worth checking oil before transport days and long runs. Gas units get moved around more than shop compressors, and that is usually when avoidable engine issues start.
