Everything you need to know about air boosters

Your asset for more pressure

Some industrial tasks demand more pressure than a standard compressor can deliver. That’s where air boosters prove their worth. By elevating existing compressed air to much higher levels, they unlock precision and power for processes such as laser cutting, PET bottle production, pressure testing, and gas handling.

The guide explores the main types of boosters while highlighting how each meets different demands for efficiency, durability, or purity. It also draws attention to practical choices between air and nitrogen boosters, and the factors that keep them reliable: energy use, continuous performance, and quality components.

In the end, the value of a booster lies in its impact. With the right unit, businesses gain higher productivity, cleaner results, and fewer interruptions, an invisible but vital advantage across countless industries!

Introduction

Compressed air is an essential element that powers a lot of industrial tools and machinery. However, some tasks require air pressure levels that exceed the capabilities of standard air compressors. This is where air compressor boosters come into play. By amplifying the pressure of already compressed air, these boosters ensure that high-pressure requirements are met.

Why do we need high-pressure air?

Compressed air can be used to power pneumatic tools and in manufacturing operations. While standard air compressors can provide pressure up to 13 bar, some applications require much higher pressures, ranging from 25 to 1,000 bar. For example, high-pressure air is essential for tasks such as laser cutting, PET bottle production, strength testing, or industrial cleaning. Without the appropriate pressure levels, these processes can suffer from inefficiencies and decreased performance.

What is an air booster?

Now let's take a closer look at this equipment. An air (or nitrogen) booster is a specialised device that works in conjunction with a standard air compressor to increase the pressure of already compressed air. Using a combination of valves, cylinders and pistons, the booster compresses the incoming air to significantly higher pressures. This allows outlet pressures of up to 1,000 bar to be achieved, depending on the application. 

Types of air compressor boosters

There are three main types of air boosters:

Single-Stage boosters

In single-stage boosters, the compression is done by only one step. These are generally used where a moderate increase in pressure is required. Besides, they are more energy-efficient and less expensive when used for low-pressure requirements.

Multi-Stage boosters

Multi-stage boosters include more than one stage of compression to reach higher levels of pressure. Such boosters should be used where extremely high pressures are required because the increased workload can be managed efficiently.

Oil-Injected boosters

They use oil for lubrication and cooling in the stage of compression. They are strong and long-lasting thus they can be used in heavy-duty applications. However, they may need more filtration to make sure about the purity of air.

Applications of air compressor boosters

Boosters are used in several industrial applications such as, laser cutting, PET bottle blowing, metallurgy, gas handling or pressure testing.

Focus on nitrogen and air boosters

Boosters can be of two types: nitrogen or air
 
Nitrogen and air boosters are not used for the same industrial applications. They each have their own specific characteristics. So, to choose the right one, some criteria must be taken into account:

1.    Cost: Consider whether the initial price of the booster is minimal compared to its energy consumption. Opt for a smaller, less powerful booster to reduce energy costs.

2.    Energy consumption: Electricity consumption is a significant expense. It is therefore best to choose high-efficiency models to reduce your energy consumption.

3. Continuous operating capacity: Ensure that the booster pump can operate 100% of the time when necessary.

4. Reliability: High-quality components and design contribute to the reliability of the booster pump, minimising downtime and production losses. 

Selecting the right air compressor booster

Choosing the right booster involves evaluating several factors. They include pressure requirements, the type (air or nitrogen, single-stage, multi-stage, or oil-free), the levels of energy efficiency, installation flexibility and the continuity of operation.

Maintenance and safety tips

Regular maintenance is crucial for the longevity and optimal performance of air compressor boosters. Here are some tips:

  • Routine inspections: Regularly check for wear and tear, leaks, and other issues. 

  • Lubrication: Ensure proper lubrication for oil-injected boosters to prevent overheating and damage. 

  • Filter replacement: Replace filters as needed to maintain air purity and prevent contamination. 

  • Safety practices: Follow safety guidelines to prevent accidents and ensure safe operation.

Conclusion

For businesses that need air or gas at high pressure, air compressor boosters are essential equipment. These boosters help in industrial processes by providing high pressure air that has already been compressed. Regardless of whether you need a single-stage, multi-stage, oil injected, or oil-free booster, the right model will always be based on your needs. The right booster will improve your industrial applications productivity, energy efficiency, and performance.Forme
