Highlights

Ideal For

• Mobile Tire Service The pontoon tank design keeps the center of gravity low, making it stable enough to run in the back of a bouncing service truck for inflating skidder tires or reseating beads on the landing.
• Pneumatic Greasing Delivers perfect pressure to run pneumatic grease guns, allowing you to tension excavator tracks or grease boom fittings in seconds without hand-pumping.
• Remote Breakdown Access Weighing roughly 75 lbs, this unit can be carried by two people (or one strong tech) into tight spots where a truck-mounted compressor can’t reach, such as a feller buncher stalled down a muddy skid trail.
• Winterizing Camp Water Provides ample volume (6.9 CFM @ 40 PSI) to blow out water lines in bunkhouses or camp showers before the freeze sets in, preventing burst pipes.
• Light Air Tools Capable of running 1/2" impact wrenches for small repairs, air ratchets, and die grinders for sharpening harvester teeth in the field.

'Need to Knows'

• Honda GX160 Power Powered by the legendary commercial-grade Honda GX160 (163cc) engine, ensuring it starts on the first pull in cold weather—unlike cheaper residential engines.
• Oil-Free Pump Features a low-maintenance Direct Drive Oil-Free pump. Note: While convenient for cold starts, this is louder than a belt-drive unit and designed for intermittent service, not continuous heavy-duty grinding.
• Pontoon Stability The twin 2-gallon tanks (4 gallons total) act as "pontoons," providing a wide, stable base that won't tip over in your truck bed like vertical pancake compressors do.
• Patented Cooling Engineered with a specialized 2-piece cooling system that extends the life of the oil-free pump by keeping operating temperatures lower than standard direct-drive models.

Warranty & Specs

• Air Delivery Delivers 5.0 CFM @ 90 PSI and 6.9 CFM @ 40 PSI with a maximum pressure of 155 PSI.
• Engine Specs Honda GX160 OHV (Overhead Valve) with a ball-bearing supported crankshaft for durability and fuel efficiency.
• Controls Features a "High-Flow" regulator and liquid-filled gauges that are vibration resistant, ensuring you can read accurate pressures even on a running machine.
• Dimensions & Weight Measures approx. 22" L x 24.5" W x 21.5" H and weighs ~75 lbs (Dry), making it the most powerful "hand-carry" gas unit on the market.
• Manufacturer Warranty Covered by DeWalt's 2-Year Limited Warranty on the pump and 3-Year Engine Warranty (via Honda).

Product Info

DeWalt 4-Gallon Gas Air Compressor

The "Rapid Response" Unit for Service Trucks

When a feller buncher goes down two miles deep on a muddy skid trail, you can’t always get the service truck close enough to use the main compressor. The DeWalt 4-Gallon Gas Air Compressor bridges that gap. It is the ultimate "grab-and-go" solution for mobile mechanics who need independent, gas-powered air without the weight of a massive wheelbarrow unit.

The heart of this machine is the legendary Honda GX160 commercial engine. Unlike the residential-grade engines found on box-store compressors, the GX160 is built to start on the first pull in freezing temperatures. This reliability is non-negotiable when you are alone on a landing and need to seat a tire bead or power a pneumatic grease gun to tension a track before the sun goes down.

Designed specifically for stability in transport, the unique "pontoon" tank configuration features two 2-gallon tanks side-by-side. This gives the unit a low center of gravity, meaning it won’t tip over in the back of your pickup while bouncing down logging roads. It’s a compact footprint that leaves plenty of room in your truck bed for fuel drums and spare parts.

Performance-wise, it delivers 5.0 CFM at 90 PSI (6.9 CFM at 40 PSI). While this isn’t designed for running 1-inch impacts all day, it is perfect for the essential field tasks: inflating skidder tires, running 1/2" impact wrenches for light repairs, and powering air ratchets. The high-flow regulator and liquid-filled gauges are built to withstand the vibration of the job site, giving you accurate readings every time.

One of the biggest advantages for cold-weather operations is the oil-free, direct-drive pump. Because there is no pump oil to thicken in the winter, this unit avoids the sluggish startups common with belt-drive compressors in sub-zero conditions. It features a patented two-piece cooling system that keeps the pump running cooler than standard direct-drive models, extending the life of the seals.

The DeWalt 4-Gallon Honda Powered Air Compressor is the perfect "second lung" for your operation. It’s light enough for two guys to hand-carry into a tight spot but powerful enough to get a machine back up and running. Add this independent air source to your fleet and ensure you have pressure wherever the job takes you.
