Air Breathers for Hydraulic Applications 

In a hydraulic system, air can enter the system in several ways. For example, air can be drawn in through leaking seals or loose fittings. Once air enters the system, it can cause several problems. 

First, air bubbles can compress, reducing the system’s overall efficiency. In addition, air bubbles can act as an insulator, preventing heat from being transferred properly. As a result, air bubbles can cause hydraulic systems to overheat and fail. 

One way to help prevent air from entering a hydraulic system is to use an air breather. An air breather is a device that allows air to flow into the system while preventing fluid from escaping. By keeping air out of the system, an air breather can help to improve its overall efficiency and prolong its lifespan. 

What is an Air Breather?

Air breathers allow air to enter the hydraulic system air breather and tanks while keeping water out. They are typically used in applications where air compressors generate hydraulic power, such as in construction equipment or offshore drilling rigs. 

Air breathers help to prevent water from entering the system and damaging the air compressor. They also help to keep the air compressor from over-heating by allowing air to circulate inside the unit. 

In addition, air breathers can help extend a hydraulic system’s life by preventing corrosion and wear. Although air breathers are not required in all applications, they can offer significant advantages in terms of performance and durability. 

  • It keeps water out of the system 
  • It prevents corrosion and wears 
  • It helps extend the life of a hydraulic system 
  • Protects your investment in hydraulic equipment 
  • It keeps your equipment running smoothly for longer. 

Why Do We Need a Hydraulic Air Breather?

Hydraulic system air breathers are essential components of hydraulic systems. The filter element in the hydraulic air breather filters has to be replaced on a regular basis to function properly. 

The blockage might create a partial vacuum inside the reservoir if hydraulic air breathers are not replaced when needed. Cavitation can lead to premature pump failure if hydraulic air breathers are not replaced when needed and blockage occurs. 

Hydraulic system air breathers are essential to prevent blockage and cavitation in hydraulic systems. Replacing hydraulic air breather filters regularly will keep your hydraulic system functioning correctly for a longer time. 

What Types of Air Breathers are There?

There are four main types of hydraulic hose breathers: risers, dipsticks, spin-on breathers, and threaded breathers. The most common of these is the 3/4 inch NPT. Each type of air breather has advantages and disadvantages, so choosing the one best suited for your hydraulic system is essential. 

  • Risers are typically used in applications where there is a need for a large amount of airflow. They are also less likely to become clogged than other types of air breathers. 
  • Dipsticks are less expensive than risers and are often used in applications where there is a limited amount of space. Spin-on breathers are more expensive than risers and dipsticks, but they are less likely to become clogged and provide more airflow. 
  • Threaded breathers are the most expensive option, but they offer the best protection against contamination and provide the highest airflow. 

When choosing a hydraulic hose breather, it is crucial to consider the needs of your hydraulic system. Choosing the wrong type of air breather can result in decreased performance and increased wear on your hydraulic components. 

Features of a functional air breather that you should look into include:  

  • Replaceable filters 
  • Spin-on features 
  • Flange or welding mounting 
  • Threaded connection 
  • Bayonet (1/4 turn) 
  • Nylon or cast aluminum cap available 
  • Pressure valves or no pressure valves can be selected. 
  • Cap locks are available. 

How to Choose the Right Hydraulic Air Breather for Your Needs?

Breathers are essential to hydraulic system air breathers as they prevent moisture and contaminants from entering the system and damaging components. Choosing the right hydraulic air breather for your needs is crucial to running your system smoothly. 

There are a few key considerations when selecting an air breather filter. 

  • Size of the unit. The air breathers should be sized appropriately for the volume of hydraulic fluid in the system. 
  • Consider the environment in which the system will be operating. If the system is exposed to harsh conditions, choosing a filter that can withstand them is important. 
  • Consult an expert to ensure you choose a filter compatible with your hydraulic system.
