Buying Guide for 2 stage air compressor

The market is filled with a lot of two-stage air compressors, and all of them promise to offer outstanding features not seen in its competitors. However, not all of them live up to the promise and fall short. As such while looking to purchase a two-stage air compressor, there are a few things to look out for and consider before making a purchase. This guide will help you to find the best two-stage air compressor which will satisfy your needs.

1. The Power: The first and foremost thing to consider when buying a two stroke air compressor is its power. The more power an air compressor has, the better its performance will be. When we look at two stroke air compressors, there are two factors which decide its power and they are Horsepower (HP) and Cubic Feet per Minute (CFM). The Horsepower dictates the output and the overall power an air compressor will have, and as such the more the horsepower, the higher the pressure a compressor can generate whereas the Cubic Feet per minute (CFM) indicates the air volume capacity of the air compressor. As such if you wish to power multiple types of equipment, then an air compressor with a higher HP and CFM should be selected.

2. The Storage Capacity: All two-stroke air compressors comes with air tanks of varying capacities for storing air to power various equipment. The capacity of Air compressors are measured in gallons, and they range anywhere from 60 gallons to 200 gallons. Therefore, a larger tank will be able to supply air to multiple types of equipment without needing many start-ups, while smaller tanks can supply power to only a limited number of equipment. Most modern air compressors come attached with a self-regulator which can regulate the pressure of the air based upon the tools that are being utilised.

3. The Power Supply: Coming to the power supply, two-stroke air compressors are generally of two types, i.e. Electrical, and Gasoline powered Air compressors. Most of the air compressors are generally electrical powered ones. Electrical compressors are easier to maintain than gasoline ones, are quieter to operate, and can work in almost any environments which have a power supply. The voltage required to run electrical air compressors varies, however they mostly start at 120 volts. Gasoline air compressors, on the other hand, are better suited for outdoor environments and places with unreliable electricity. A few advantages of gasoline air compressors is that they are more portable and also produce more HP and CFM than electric air compressors.

4. The Style: Coming to its style, the design of air compressors are generally of two types, i.e. Horizontal and Vertical Orientation. The type is decided by the placement of the air tank which may be horizontal or vertical respectively. The style which you will purchase depends on your own needs, and therefore if you have limited space to store your compressor than go for a vertical one, however, if you have more space to play with then purchase a horizontal one. One thing to keep in mind is that the style doesn’t affect the performance of the compressors.

FAQ’s on 2 stage Air Compressors

How frequently should the oil be changed?

Just like with a car engine, the oil in an air compressor needs to be changed on a routine basis. The duration after which the oil should be changed varies, however usually the oil should be changed after 7000 to 8000 hours of use, or after every three months.

When should the air filter be cleaned/replaced?

Most air compressors come with an air filter for filtering any debris or impurities that may make its way to the air tank. It is suggested to clean the air filter every week or as frequently based on the environment. Coming to replacing the filter, it should be done when the filter becomes hard, develops holes or tears in it.

Is it safe to run an air compressor on a generator?

It is technically possible to power a two stroke air compressor using a generator; however, it is not recommended. This is because generators generally do not provide a stable current supply and they tend to have fluctuations. As such, operating an air compressor with fluctuating current may harm the components over time.

Should I go for an electric or gasoline two-stroke air compressor?

This depends on where you plan on using the air compressor. If you plan on using your compressor at home or a place with consistent power supply, an electric air compressor is the better buy. However, if you plan on using your compressor in a place with no power than a gasoline one is the better option.

Conclusion

All the above two stroke air compressors are great products and will be able to satisfy your compressed air needs. However, the one product that stands out from the rest is the NorthStar 2-Stage Air Compressor Pump. This air compressor comes with all the bells and whistles required from a good two stroke air compressor. However, its best feature is its affordable pricing which makes it very appealing from the other two.

If you happen to have a higher budget and happen to be searching for an air compressor with little to no compromises, then the Campbell Hausfeld Two-Stage Air Compressor is the one to get.
