Jenny Gas-Drive Two-Stage Wheeled Portable Series

Jenny Gas-Drive Two-Stage Wheeled Portable Series

The Jenny Gas-Drive Two-Stage Wheeled Portable Series is the definitive choice for remote jobsites where “shop air” is a necessity but electricity is unavailable. These units are built to deliver high-pressure airflow (up to 175 PSI) for the most demanding applications, from heavy-duty impact wrenches and pneumatic grinders to high-pressure framing and commercial roofing.

By combining legendary Honda GX Series engines with Jenny’s two-stage cast-iron pumps, these machines provide a mobile power plant capable of a 100% duty cycle in the harshest environments.

The GT9 Series (Honda GX270 Powered)

The GT9 series features the heavy-duty “G” two-stage pump driven by a 9 HP class Honda GX270 engine. This combination is optimized for crews that need high pressure and fast recovery without the bulk of a full-size trailer unit.

• Models: GT9HGB-8P2, GT9HGB-15P2, GT9HGB-17P, GT9HGB-30P
• Performance: Delivers a maximum of 175 PSI, allowing for longer hose runs without significant pressure drops.
• Best For: High-production commercial roofing, bridge work, and large-scale residential framing.

The W-Series (Industrial Displacement)

The W-Series represents the peak of portable pneumatic power. These units utilize the massive “W” series pump, which features a larger bore and increased stroke for maximum air displacement.

• W11HGB-30P: Driven by the Honda GX340 (11 HP class) engine. This model is built for sustained, high-volume air demands.
• W13HGB-30P: The flagship of the gas portable lineup, powered by the Honda GX390 (13 HP class). It provides the highest CFM available in a two-stage wheeled unit.
• Tank: Both models come standard on a 30-gallon horizontal tank to provide a massive air reserve for heavy-duty tools.
• Best For: Industrial maintenance, remote mechanic service trucks, and sandblasting.

The Two-Stage Gas Advantage

• 175 PSI Maximum Pressure: The two-stage design compresses air in two steps with intercooling in between, allowing you to reach higher pressures more efficiently than single-stage units.
• Honda GX Engines: Renowned for easy starting, fuel efficiency, and legendary longevity, these engines feature an overhead valve (OHV) design for cooler operation.
• Cast-Iron Construction: Jenny’s pumps feature cast-iron cylinders and crankcases, ensuring they can be rebuilt and serviced for decades of use.
• Constant Run Control: Each unit is equipped with a high-quality pilot valve and pneumatic throttle control. The engine idles down when the tank is full, saving fuel and reducing noise, then ramps up automatically as air is used.
• Advanced Cooling: Finned intercoolers dissipate heat rapidly between the first and second stages, ensuring the air reaching your tank is cooler and holds less moisture.

Tank & Mobility Features

• Heavy-Duty Frame: All units are mounted on a rugged, powder-coated frame designed to withstand jobsite abuse.
• Maneuverability: Features “stroller” style handles and heavy-duty pneumatic tires to navigate mud, gravel, and debris.
• Professional Components: Includes stainless-steel braided discharge hoses, high-visibility pressure gauges, and a specialty manual unloader for effortless cold-weather starts.

Pro Tip: For service truck applications or stationary use on a jobsite, the 30-gallon (30P) models are highly recommended. The larger tank acts as a buffer, allowing the engine to spend more time at idle, which extends the life of both the engine and the pump.
