1 HP Oil-Less Air Compressor Review: Rolair JC10

Rolair JC10 1 HP Oil-Less Air Compressor

When it comes to quiet oil-less air compressor, it must be mentioned that the Rolair JC10 is undoubtedly one of the best at the moment. Equipped with a1 HP motor that runs at 1725 RPM, the JC10 is rated at 60 decibels. It makes less sound than a normal conversation (65 decibels). This oil free air compressor is therefore a great option for anyone working in an area where noise is a major issue. Watch the video below that shows the noise comparison between this new oilless JC10 compressor and two other oil-free models.

The Rolair JC10 is a single stage compressor that means the air is only compressed once. Generally, single stage, compact oil-less compressors are ideal for light- to general-duty applications. They are meant for minor household tasks, like inflating tires and sports equipment. They can also be used for occasional pneumatic tool use. Unless you need higher pressure, there is no need to buy a two stage air compressor.

In this unit, the compressing pump has two cylinders. Like other oil-less compressors, the cylinders are made of aluminium. Compared to cast iron, aluminium tends to be less durable. But when it comes to portable air compressors, the weight-saving advantage of aluminum is desirable. The oil free pump provides maintenance-free operation.

To drive the pump, this consumer-grade air compressor is powered by a 115 volt, 60 hertz motor. The motor draws only 8 Amps that allows you to use standard 15-Amp outlets. This air compressor is also equipped with an Automatic Overload Protection. Featuring a direct drive design, it requires a fraction of the maintenance of belt-drive units. But unlike many direct drive machines out there, it runs at a low RPM. As mentioned before, the motor operates at 1725 RPM. This minimizes potential mechanical issues.

This DIY type air compressor can deliver about 2.35 CFM at 90 PSI (3.80 CFM at 40 PSI). CFM displacement is 5.3 at 90 PSI. You may consider this number as the raw pump power. It is the actual delivered air that matters. CFM delivered takes into account inefficiencies. Based on the specs, the efficiency of this compressor is around 50%. Higher end models may have an efficiency of 75%. This translates to electrical costs. But for occasional use it certainly is not a big issue.

Coming with a horizontal design, the tank capacity is 2.5 Gallon. A pressure gauge is mounted on the unit to indicate the air pressure in the tank. Near the pressure switch, there is a gauge to display the pressure setting. Built for portability, this unit weighs only 39 lb. It also features a roll-cage design for extra protection. Compared with the California Air Tools 6310, the specs are very similar. But the 6310 does not feature roll-cage design.

The Rolair JC10 has received very good feedback from many buyers. Over 90% of Amazon’s customers have given this product either 4 or 5 stars which means they absolutely adore it. At this time of writing, this oil free air compressor has an impressive rating of 4.7 stars out of 5 on Amazon.

As with any compressor, some negative views have also been voiced by the users. One of the most common complaints about the JC10 is in regard to its pressure gauges. The viewing angle needs to be improved.

Further complaints have been made about the drain valve. Basically, it helps to remove any water from the tank. It should be opened after every use to prevent rust formation. However, according to some customers, the drain valve on this unit is not easy to use.

Despite the criticisms that have been leveled at this product, most of the customer reviews have been very positive. They have reported that it works as expected. It is not designed to run air tools that require a continuous flow of air. But if you are planning to use if for your finish and brad nailers, then considering the customer feedback, you will be happy with its performance.

Obviously, it is not totally silent but based on the customer feedback, it is quiet as advertised. You could have a conversation right next to it. It is very convenient to have a quiet compressor. Customers have also found that it produces little vibration, making it perfect for indoor use.

The lightweight design is another plus point of this product. It is light enough to carry easily. Further, reviewers have keenly expressed their appreciation for the solid construction of the small compressor.

The Rolair JC10 is not a high output compressor. If your jobs require frequent use of various pneumatic tools, it will not be sufficient. Grinders and sanders require more CFM. But if you need a quiet, well-built small air compressor, then this should work for you.
