Rolair 9 Gallon Twin Tank Compressor with Dual Controls

Description

Operate dual-mode pneumatic framing with the Rolair 9-Gallon Dual-Control Compressor to switch between continuous-run pilot unloader operation for high-production framing and start-stop pressure switch operation for intermittent finish nailing. A commercial 9 HP gas engine powers a 2-stage cast-iron pump delivering 20.1 CFM at 90 PSI across dual horizontal tanks up to 135 PSI. Framing contractors run six framing nailers simultaneously without pressure drops. Sized for jobsite wheeling, the gas compressor requires outdoor ventilation.

Two-Stage Dual-Control 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. Switching to continuous-run mode holds engine RPM steady while the pilot valve unloads head pressure, eliminating engine speed fluctuations on high-production framing decks. Initial tank fill takes 42 seconds, with recovery cycle time clocking at 11 seconds across the nine-gallon tanks.

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. Sized for jobsite wheeling, the bare gas compressor weighs 310 lbs, measuring 48 inches long, 28 inches wide, and 30 inches high, rolling on a flat-free tire.

Key Features of Rolair 8422HK30-DC

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

• Dual-control system switches between continuous-run pilot unloader and start-stop pressure switch operation cleanly.
• Commercial 9 HP OHV gas engine delivers reliable power with electric key start and low-oil alert 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 cleanly.
• Heavy-duty flat-free front wheel rolls over jobsite mud, rocks, and extension cords without puncture deflation downtime cleanly.

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. Routine care requires checking engine oil and pump oil levels daily, draining tank petcock valves daily after shutdown, and inspecting drive belt tension every 250 operating hours.

Factory Warranty Hardware Manifest

Rolair backs this gas-powered air compressor with a 1-Year limited manufacturer warranty against pump casting defects and tank weld leaks, with Honda covering the commercial engine for 3-Years. The factory crate includes one assembled 9-gallon gas compressor, flat-free tire, belt guard, and user manuals.
