The Perfect Combination of Performance and Portability
The Hitachi EC119SA 4 Gallon Dual Stack Air Compressor offers all the features of a large compressor in a compact and portable unit. Its exceptional power and durability make it the perfect tool for any action-packed job. Equipped with a robust 2.5 HP induction motor running at 15 amps, coupled with a cast iron pump cylinder boasting oversized bearings and oil lubrication, this compressor is designed to deliver outstanding performance.
Power-Packed Performance in a Compact Design
The Hitachi EC119SA 4 Gallon Dual Stack Air Compressor combines power and portability in an impressive way. Its quiet yet mighty 2.5 HP induction motor runs smoothly while a large metal cooling fan keeps the temperature in check. The oil-lubricated pump crankcase with oversized bearings ensures long-lasting reliability. The cast iron compressor head, with its large fins for efficient cooling, is encased in a sturdy steel roll cage that doubles as a convenient carrying handle. The control panel, conveniently located at the front, features separate tank and line pressure gauges, a secure lock line pressure regulator, and two quick connectors. The compressor’s two gallon tanks are equipped with individual ball valve drains. Additional features include thick rubber feet for stability, a manual overload protection button, and a cord wrap for neat storage.
Unboxing and Easy Setup
Upon receiving the Hitachi EC119SA Air Compressor, we were pleased with its secure packaging in a spacious heavy-duty cardboard box. Despite minimal styrofoam padding, the compressor remained firmly in place during transit. The package also included an 8-ounce bottle of synthetic oil for the crankcase and clear instructions for use.
To set up the compressor, we followed the manual’s instructions. We poured the full bottle of oil into the crankcase and inserted the included dipstick into the fill hole. No additional assembly or parts were required. Closing the tank drain, we plugged the compressor into a power outlet and switched it on. Surprisingly, the compressor operated at a very tolerable noise level, allowing for easy conversation without shouting. We decided to pair it with the Hitachi NR90AE Round Head 3-1/2″ Framing Nailer to test its capabilities in the field.
Impressive Performance and Fast Tank Fill
One of the standout features of the Hitachi EC119SA Air Compressor is its remarkable tank-filling speed. Thanks to its powerful motor and premium compressor pump, the tank fills up rapidly. What sets this compressor apart from others, like the Bosch CET4-20W, is its impressive 4.0 CFM air volume at 90 PSI. This substantial air output enables simultaneous use of multiple nailers without the need for continuous compressor operation.
A Reliable Companion on the Job
We put the Hitachi EC119SA Air Compressor to the test at a construction site where a framing crew was working on a large hipped roof for a new screen porch. Initially, some doubted whether this compact compressor could “keep up” in terms of delivering sufficient air volume to sustain constant use of the nail gun. However, they soon discovered their mistake. This little compressor proved that it is indeed up to the task. The only minor inconvenience we encountered was that it required extra effort to start on cold mornings. We attribute this to the thicker oil when cold, which requires additional motor power until it warms up. Once the compressor was up and running, it operated flawlessly throughout the day.
The only complaint we received from the crew was regarding its weight. Weighing 64 pounds, it is comparatively heavy for its compact size. This can become cumbersome when carrying it up and down stairwells to reach different work areas. To alleviate this issue, we opted to use a 100-foot hose to minimize the need for relocation. Aside from this minor drawback, the Hitachi EC119SA 4 Gallon Dual Stack Air Compressor proved more than capable of handling various tasks, including roofing, framing, and veneer nailing.
In Conclusion: A Reliable and Versatile Compressor
The Hitachi EC119SA 4 Gallon Dual Stack Air Compressor impresses with its quality build and heavy-duty construction. It is an excellent addition to any job site, offering a perfect combination of power and portability. While a few minor downsides exist, the compressor’s numerous positive features more than make up for them.
