Making the right choices when choosing your Compressor System


A lot of careful planning goes into the decision to purchase an air compressor system. Buyers have to contemplate a variety of factors including the amount of air pressure needed, what type of system fits their needs and how much they are able to invest in a system.

If you don’t have the knowledge and experience that Nessco Pressure Systems has when choosing the right system, mistakes can be made when selecting what to buy which can cost you in the long run. 

Let us help you out by pointing out some of the things to look out for when selecting your compressor system.



Deciding on the correct size of compressor is key to the efficiency of your business. The wrong size can lead to problems with production and wasted energy which can increase overall costs. It’s also wise to plan ahead and think what may be your needs in the future.


One of the key determinants to selecting size is the amount of pressure required. Your air compressor has to be able to provide enough air pressure so that you are able to complete the task at hand. Anything less will not work, rendering your system useless. This is why it’s important to know the pressure that is required beforehand so that you are able to choose a powerful enough compressor.

Air Flow

Another important factor to consider is the correct air flow needed for the compressor. To put it simply, flow is the ability of the compressor to perform a task within a given time period. The amount of flow needed is determined by the length of time required to complete the task. If your flow isn’t sufficient enough, your compressor will need to build up pressure inside its reserve tank which suggests that the compressor you’ve chosen might be undersize. Again it’s important to know your requirements before making a choice.

One of the best ways to figure out the correct flow needed is to perform a compressed air audit which can be conducted by our knowledgeable NPS staff.

Future Expansion

It’s also important to consider what your air usage might be like in the future when making your decision. While your current air pressure needs might be small, a company that plans ahead and selects an air compressor that will account for the growth of their business can save themselves a considerable amount by not having to purchase subsequent compressors systems.



The type of compressor your business needs is another factor you need to consider at decision time. Two of the more popular options available are piston and rotary screw compressors.

Piston Compressor

The piston compressor is one of the most economical options available. This is a small and robust air compressor that is often used in small workshops, tire shops or manufacturing facilities. One of the highlights of the piston compressor is that they are relatively easy to maintain and usually require minimum investment however this doesn’t mean you should buy one this instant!

Piston compressors are designed for intermittent use which means it can only work about 50-60% of their duty cycle. These units also need time to cool off between their cycles otherwise they will overheat and fail. Another factor to consider is that piston compressors can be extremely loud when operating, so you may want to take into account whether any employees will be working close by.

Rotary Screw Compressor

The rotary screw compressor is designed for operations that require a constant compressed air supply. While piston compressors may only need to be in use for 50% of their duty cycle, rotary screw compressors may be used up to 100% of their duty cycle and are generally built to have long, reliable lifespans. The amount of popularity for screw compressors means there are plenty of options available which suit a range of budgets and needs.

Compressed Air Safety Tips

Compressed air can be extremely dangerous if not used in a safe manner.


To reduce the risk of injury, it is recommended that the following guidelines are considered and implemented:

1. Never apply compressed air to the skin or direct it at a person

Even air at a pressure of 15 psi can cause serious injury. Never use a compressed air hose to clean dirt or dust from your clothing or body.

2. When using compressed air for cleaning purposes, ensure pressure does not exceed 30 psi (per OSHA regulations)

Always use goggles or a face shield over approved safety glasses for this application.

3. Wear ear protection

Exposure to excessive noise can damage hearing. Noise reducing mufflers can be fitted to machines to lessen the noise health hazard.

4. Never crimp, couple, or uncouple pressurized hose

Shut off valves and bleed down pressure before making any hose connections.

5. Use heavy duty clamps and fittings made especially for compressed air hose

Use only the correct type and size of hose end fittings and connectors.

6. Never use frayed, damaged or deteriorated hoses

Always store hoses properly and away from direct sunlight. A hose failure can cause serious injury. Hose reels can decrease your chances of injury, as well as help hoses last longer.

7. When blowing compressed air through a hose or airline, ensure open end is held securely

A free end can whip and can cause injury. Open the supply valve carefully and ensure that any ejected particles are restrained. A blocked hose can become a dangerous “air gun”.

8. Keep compressors regularly serviced

Keeping up to date with your compressor’s servicing schedule ensures air quality is controlled, and reduces the risk of over pressure, and component failure.

9. Do not use air directly from a compressor for breathing purposes

Only do so if the system has been specifically designed for such purpose, and suitable breathing air filters and regulators are in place.

10. Isolating valves should be of the self venting type and designed to be locking in the “off” position

This ensures that air pressure cannot be applied accidentally while the machine is being worked on.
