Buying Guide – How To Choose A Good Air Compressor?

Amazon is one of the best places to buy a new air compressor in Canada. It has everything from models for low budget buyers to professional machines. In either case, consider educating yourself on how an air compressor works.

Buying Guide - How To Choose A Good Air Compressor

Air pressure

Each tool requires pressure and air volume, which will usually be mentioned in the product description. These values ​​also vary depending on the model and brand of equipment. The amount of air the machine can deliver is measured in Standard Cubic Feet Per Minute or SCFM. Typically, small tools will require a flow rate of 0 to 5 SCFM. Extensive tools will only work with a quantity of air evaluated at 10 SCFM or more.

The frequency of use is also a point that you should not ignore. For regular and intensive use, we advise you to take a robust model. Engine performance will prevent overheating and overconsumption. The simultaneous and permanent power supply of two tools is possible if the needs of each piece of equipment are met.

Regarding the air pressure circulating in the tank, the latter is expressed in pounds per square inch or PSI. On low capacity models, it is equal to 90 PSI. High-end machines develop pressure from 150 to 200 PSI. Expressed in HP, the power rating of a compressor is an excellent way to assess its performance. As with motor vehicles, engine power is measured in horsepower. By way of comparison, it is between 1.5 and 6.5 CV.    

Tank capacity

The operating time of a pneumatic tool will be calculated according to the capacity of the tank. Tank sizes vary from 1 to 80 gallons. Feeding a mechanism requiring a high volume of air will need a large capacity bowl. On the other hand, if the tooling is used discontinuously, a low capacity tank will do the trick.    

Your needs

To inflate a balloon or a bicycle wheel, opt for the so-called portable models. Its purchase will also allow you to check the pressure of your tires or even to use a low-pressure gun. Typically, these machines work with a 1.5 horsepower motor that can deliver a maximum pressure of 8 bar. Not cumbersome, the capacity of their tank turns around 6 to 8 litres.  

Intended for small do-it-yourselfers, domestic compressors are mainly used in nailing, stapling, cleaning and tire inflation. Easy to move, these devices incorporate two transport wheels. Opt for a compressor providing a flow rate of 15 m3 / h and integrating a 1.5 horsepower motor to carry out household tasks.  

With an average capacity of 200 litres, these machines have been designed for intensive use. For regular use, I prefer models with a 100 to 150-litre tank. The power of the compressor unit which equips these machines will be between 2 to 3 horses. Powering pneumatic tools will require the use of a professional compressor. Of all the existing variants, this type of compressor is by far the most efficient.

frequently Asked Questions

Q1: How does an air compressor work?

To function, an air compressor has an inlet and a relief valve that ensures the suction and discharge of air. The pump is used to compress the air while the tank acts as storage. First, the compressor sucks in the ambient air and then creates a vacuum to reduce its volume. 

As soon as the tank reaches its maximum pressure, the machine will automatically stop. The engine will turn on when the pressure measured at the reservoir level reaches a certain threshold. Those who are wondering know that an industrial air compressor works precisely the same way.

Q2: Compressor with oil or without oil?

If you use pneumatic tools, give preference to oil compressors. A lubricated machine will last longer than a compressor without oil. However, the air it blows will show traces of oil. To eliminate them, it will be necessary to invest in an air treatment product. Also, note that oil compressors are stored vertically. An unlubricated model is primarily used for tire inflation. In addition, the air it gives off is cleaner. 

Q3: How to use a compressor?

Before turning on your machine:

  1. Remember to screw on the lower valve located at the tank level.
  2. Check that the air filters are in place.
  3. Wait for the tank to fill before adjusting the air pressure.

Once done, plug the device into a power outlet and startup. 

Meanwhile, take a look at the dipstick and upgrade if necessary. To install an air tool, plug it into the connector on your device. Then adjust the air pressure according to the manufacturer’s recommendations and the type of tool you are using. These tips are valid for all models, regardless of their category.    

Q4: How to make a compressor quieter?

The soundproofing of a compressor depends on the choice of a good location. Indeed, the vibrations that the engine produces will propagate in the ground, hence the manufacturers’ usefulness of the shims. If your machine is still noisy, you can install an anti-vibration mat—Line the walls and ceilings with soundproofing foam which also reduces noise pollution. 

To prevent the room from being airtight, it will be necessary to develop a ventilation duct. Choose models with three layers. This technology will provide an excellent level of insulation. Thus, the air will be able to circulate freely.

Q5: Which oil for a compressed air compressor?

The oil you should use on your compressor will depend on its configuration. As a rule, its reference is marked on the leaflet. The use of inexpensive oil, of poor quality or not in conformity with the device, can cause seizure of the pump. 

Each lubricant has its specificities, whether in terms of composition, viscosity or manufacturing standards. An oil change done in the rules of the art protects you from mechanical breakage while reducing the cost of maintenance. Following the manufacturer’s recommendations will prevent you from buying a new compressor.
