03. Eagle EA-5000  Air Compressor Review

As the name implies, this unit is the quietest professional grade compressor available in its class. If your main concern is noise, you have no option other than Eagle EA-5000. It’s so quiet that you may not even hear it operating.

When you have Eagle EA-5000 in operation, you don’t need to instruct your project members by yelling anymore. Eagle’s silent series allow clear communication in the Jobsite.

What makes the pump distinguished from other models available is slow RPM motor. Since the engine runs slowly, this reduces noise, heat, and friction. Consequently, the pump lasts longer.

You may think a slow RMP motor cannot provide sufficient output. But the compressor generates ample gas with its dual intake system that sucks twice the air at the same time.

The tank has a 5-gallon capacity and is designed with a side stack style to compact the overall size. Eagle engineered this unit with the double piston to produce a massive airflow of 5 CFM, allowing you to run your impact wrench smoothly.

When moving the compressor one Jobsite to another, you can rely on the eight-inch flat-free tires which even works on the rough terrain. The folding handle makes the portability and storage further easy.

What I Like

  • The ultra-quiet operation for a calm environment
  • Dual intake system for twice air
  • Oil-free function with double piston
  • Low amp draw for highest life expectancy

What I Don't Like

  • Not suitable for high power tools

When you are afraid of your compressor breaking down while in heavy operation, NorthStar helps you win your fear, Northstar engineered this compressor with superior technology to withstand heavy duty.

Built with a durable cast iron V-twin pump with head, the pump can dissipate the heats and works without interruption, thus maximizing life expectancy. The compressor features a belt drive oil lubed pump and bearings placed on both ends of the crankshaft, resulting in dependable operation years for years.

Moving on to the power, the 20-gallon tank is ASME certified that can be used in commercial shops, and has enough capacity to retain a massive amount of pressure to operate an air ratchet, impact wrench, and other powerful air tools. With 5 CFM at 90 PSI, the compressor can also be used to run sandblaster, nailer, airbrush, spray gun, and more.

Not only is this unit up to the mark when considering durability and power, but in terms of transportation as well. The vertical tank design, smooth-rolling ball bearing wheels and never- flat tire, folding handle, all this makes it easy to transport the pump site to site.

Additionally, although this piece comes wired for 115V operation with a 6 ft cord and plug, it can be rewired for 230V by an expert mechanic.

More Reviews From Us


What size air compressor is needed for impact wrench?

Impact wrenches are powerful tools designed for industrial use. They are used to loosen nuts and bolts, among other things. The air compressor required for each impact wrench differs, and the size mainly depends on the power generated by the tool. mainly 4-5 CFM is best @90 psi.

Can you run an impact wrench with a pancake compressor?

You can but you probably won’t get that much torque from the compressor. In our years of experience, we have found that a specific model runs at 2.6 SCFM @ 90 PSI. However, the product details for your tool state the average air “consumption is CFM 4.2 @ 90 PSI .”

How much torque should an impact wrench have?

An impact wrench is a tool that is used in various situations such as construction for loosening or tightening nuts and bolts that are harder to remove. An impact wrench to remove lug nuts  needs about 500 ft-lbs of torque. But if you put on too much pressure and got the lug nuts overly tightened, then you may actually need more torque than 500 ft-lbs in order to loosen them.

Bottom Line

Heavy-duty pneumatic tools like impact wrench demand high CFM, PSI, and big tank to run smoothly. Considering all these factors, I have narrowed a hundred of choices down to just five best options. Definitely, this list of top-rated air compressors will make your purchase worth and happy. All that you need is to carefully read this guide to know which one suits you best.
