Rolair 9HP (270cc) Honda 20.1 CFM@90PSI 9 Gall Twin Tank Compressor

Description

Delivering 20.1 CFM at 90 PSI, the Rolair 9HP 9-Gallon Gas Compressor powers multiple framing nailers and coil roofing guns across unpowered commercial residential framing jobsites. Powered by a commercial Honda GX270 270 cc 9 HP gas engine with electric start, the 2-stage cast-iron pump delivers 20.1 CFM at 90 PSI across dual horizontal 4.5-gallon tanks up to 135 PSI. Framing contractors run six framing nailers simultaneously without tool pressure drops. Sized for jobsite wheeling, the gas unit requires outdoor ventilation.

Key Features of Rolair 8422HK30-9HP

Commercial framing contractors and roofing crews buy Rolair 9HP 9-Gallon Gas Compressors to run large pneumatic production crews on unpowered commercial jobsites. Compare commercial gas wheelbarrow air compressor pricing to equip commercial framing trailers.

• Genuine Honda GX270 270 cc OHV commercial engine features electric key start and low-oil alert shutdown protection cleanly.
• Solid 100-percent cast-iron 2-stage pump delivers 20.1 CFM at 90 PSI, running cool at low RPM for long service life cleanly.
• Twin wheelbarrow steel tanks provide nine gallons of air storage, buffering pressure spikes during simultaneous multi-gun firing.
• Integrated pilot unloader valve regulates engine throttle automatically, idling the engine down when cut-out pressure is reached.
• Heavy-duty flat-free front wheel rolls over jobsite mud, rocks, and extension cords without puncture deflation downtime cleanly.
• Heavy-gauge steel belt guard protects the multi-blade cooling flywheel from jobsite road rocks and flying debris squarely.

Solid ASTM Class 30 cast iron forms the 2-stage pump cylinders, heads, and crankcase, dissipating high operating heat during continuous multi-gun production framing. An automotive-style balanced crankshaft turns inside heavy-duty roller bearings, supported by splash lubrication. A high-efficiency finned copper intercooler drops air temperatures between compression stages, preventing valve carbonization. Sized for jobsite wheeling, the bare gas compressor weighs 310 lbs, measuring 48 inches long, 28 inches wide, and 30 inches high.

Two-Stage Gas High-Volume Bench Limits

Pneumatic bench testing proves actual delivered air output measures 20.1 CFM at 90 PSI and 18.5 CFM at 135 PSI, supporting six framing nailers firing at rapid production rates without pressure starvation. Initial tank fill from zero to 135 PSI cut-out takes 42 seconds, with recovery cycle time from 105-PSI cut-in to 135-PSI cut-out clocking at 11 seconds across the nine-gallon tanks. The Honda engine runs at 3100 RPM under load, automatically dropping to 1400 RPM idle when the pilot valve unloads air pressure.

Commercial Framing Negative Selection Filter

The dual wheelbarrow handles balance the 310-pound machine comfortably when rolling up equipment ramps into trailers. Do not buy this heavy gas wheelbarrow unit for indoor finish carpentry trim punch lists, enclosed building operation without exhaust ventilation, or lightweight vehicle trunk storage.

• Check engine oil and pump oil levels daily before morning jobsite pull-starts.
• Drain both lower tank petcock valves daily after shutdown to stop internal steel tank rust formation.
• Inspect drive belt tension every 250 operating hours, maintaining 1/2-inch deflection at mid-span.
