Best Industrial Air Compressors For Multiple Industries [Reviewed]

Industrial Air CompressorsIndustrial air compressors come in different, shapes and sizes. Industrial air compressors are divided into 5 different types.

Those are rotary screw air compressors, centrifugal compressors, and high-pressure air compressors, rotary vane compressors, and reciprocating piston compressors. Industrial air compressors are usually misclassified. The internet is full of articles claiming to name the best industrial air compressors.

However, most of those articles are simply referring to low grade and minor capacity air compressors. The truth of the matter is that the best industrial air compressors will differ from one business to another. In this detailed buyers guide, we will review the different industries that use industrial air compressors, the types of industrial air compressors, the cooling processes and much more.

Industrial Air Compressors Types 

Centrifugal Compressors

The best centrifugal compressors are powered by integral gear or single shaft technology, handle volume flows up to 560,000 m3/h and pressures up to 205 bar. Also know as dynamic compressors, centrifugal air compressors are designed to produce big volumes of compressed air in a highly energy-efficient process. All industrial manufacturers are aware of the advantages of centrifugal technology, but those who need over 200 to 250 total horsepower tend to gain the greatest savings.

Rotary Screw Air Compressors 

Rotary screw air compressors are named after the positive displacement mechanism they use. These are gas compressors that use a rotary-type mechanism. There is very little flow surge or pulsation because the gas compression process of a rotary screw is a continuous sweeping motion. 

The two main types of rotary screw compressors are oil-flooded or oil-injected and gas rotary screw compressors. With the first type, oil is injected into the compression cavities to facilitate sealing and supply the gas charge with a cooling sink. The oil and discharge stream stay separate. The oil is cooled, recycled, and filtered. 

Heavy Duty Air Compressors

Heavy Duty Air CompressorsHeavy-duty air compressors are highly resistant to moisture, which is a good thing because it can damage and cause rust. They offer better long-term lubrication and a better defense against moisture.

These compressors have a wide range of vehicle applications as well as applications in the mobile air-conditioning and refrigeration industries. 

A lot of vehicles use them, from bus transit and long-haul trucking to construction and military vehicles. Well-known brands include Carrier, Caterpillar, CNH, and Navistar. It’s always recommended to look for ones with an acquisition system designed to protect data accuracy and quality. 

High-Pressure Air Compressors

Most high-pressure air compressors are developed to operate up to a maximum of 175 psi. The vast majority of rotary screw compressors will run between 90 and 125 psi efficiently. Some applications require high compressed air volumes in the range of 45 to 60 psi. High-pressure rotary screw compressors designed to run in this specter will consume less power because they will use a smaller motor than a machine designed to run at a higher pressure.

What Industries Use Industrial Air Compressors?

Many industries use air compressors – innumerable ones, in fact. Just have a look at the table at the beginning of this article. In this section, we’ll focus on food factories, product packaging, and wastewater treatment.   

Industrial Air Compressors for Food Factories 

Rotary screw air compressors compress food grade air, which can be used to cut and prepare products or create consistent, clean packaging. They can be used to move ingredients and food products down a process line. For example, they push powdered products through pipes by means of compressed air.

Air hoists and compressed air cylinders can move products more quickly down the line too. This is required in order to maintain the necessary production speeds. In the automated sorting of products, compressed air can also be used to power pneumatic systems like control valves. Compressed air can be used to peel vegetables and fruits and get them ready for packaging. The peel of the product is removed by a jet of pressurized air. The process is clean and efficient.

You can also use compressed air to remove nut peels or shells. You can cut food items using high-pressure compressed air. This option is usually cleaner than knives or blades.

Industrial Air Compressors for Product Packaging 

The fast sequence of heating and molding plastic packaging requires equally rapid cooling of the formed polymers. This is achieved through industrial air compressors’ water cooling systems, which extract the heat in the form of hot water at high temperatures. 

Industrial Air Compressors for wastewater treatment stations

Air compressors guarantee that the air is free of contamination as they operate. They reduce noise and vibration levels and regulate airflow via a variable speed drive.

The Cooling Process of Industrial Air Compressors 

There are several compressor cooling types, including air cooling, compressors with an integrated refrigerated dryer, and water cooling. This section explores them.  

The Air Cooling Process  

Water Cooling Process In Industrial Air CompressorsThe air compressor package has forced ventilation which contains almost all of the energy the motor consumes. Most modern compressors are equipped with air cooling. 

The Water Cooling 

This is also an efficient cooling method. A water-cooled compressor installation is a good idea because very little pressure is exerted on the compressor room ventilation system. The cooling water contains around 90% of the energy the motor uses. 

There are three types of compressor water cooling systems. They are closed systems with circulating water (including an external radiator or heat exchanger), open systems with a cooling tower (circulating water), and open systems connected to an external water supply (without circulating water).  

Industrial Air Compressor with Integrated Refrigerated Dryer

Refrigerated compressed air dryers are able to eliminate more oil and water than coalescing filters. The reason for this is because after the air is cooled and the moisture is removed, the cold air is used to pre-cool the hot incoming air, which heats up the exiting air. 


Industrial Air Compressor Maintenance Checklist

You need to check and clean or lubricate the following components

Air Filter

A dirty air filter contains particles and impurities that may corrupt the compressed air. This leads to the deterioration of end-point applications. You should clean the air filter regularly. Change it out at intervals depending on the environment.

Oil Filter

Lubricated and non-lubricated compressors alike need to have their oil filters changed. These must be completely replaced at recommended intervals, which are 6,000 hours on average. Replace your filter sooner if it gets heavily covered in oily residue before this time passes.

Intake Vents

An air compressor transforms ambient air into something that can replace electric power. It powers heavy-duty machinery effectively. Consequently, the compressor itself can only do so much to turn ordinary air into something powerful. To make sure the incoming air stays as clean as possible, check the vents regularly. This also prevents dirt from getting sucked into the system. It’s best to inspect them weekly and clean them when necessary.Intake Vents


Lubricant is one of the most crucial parts when it comes to the functions of an air compressor. It allows for smooth movement on all the internal metal parts and joints. This movement is also non-corrosive. Without lubrication, joints and parts rust because of the tension between the touching metal surfaces. Once you have rust on your hands, it will spread and destroy certain mechanical parts.


With time, the rubber on a belt will become amortized and crack in certain places. It’s therefore important to replace the belts before they break as you work or lose their tension.  Check each belt once per week to ensure they are free of wear. Once there is wear, adjust the tension or replace the belt if necessary.

Motor Bearings

Oil the bearings every 4,000 hours to protect the health and performance of the air compressor’s motor. Between each greasing, check the bearings at quarterly intervals to make sure they remain sufficiently lubricated.  IndustrialAirMotorBearingsOther things to check include amps, air dryer performance, oil levels, vibration, and temperatures.
