compressor water separators

centrifugal water separators

Centrifugal air compressor water separators are designed to induce a rotational as compressed air passes through the separator. 

Particles, oil, and water flow faster toward the outside edges and gather inside the separator housing, where they can be released after draining to the bottom. 

Centrifugal air separators can be drained manually or by installing an automatic drain system.

coalescing water separators

Coalescer water separators utilize filter elements to trap contaminants in the compressed air supply as it flows through the filter.

Compressed air is forced through the filter media from the inside of the filter to the outside, and the compressed air exits the separator. It would help if you replaced these filters periodically.

Key benefits of BISON air compressor water separators

BISON’s water separator is ideal for safely removing air compressor condensate.

A detailed guide for beginners to advanced customers

Air compressor water separators are designed to remove the lubricant from condensation within the system (water). Water separators are usually installed downstream of the compressor sump.

In compressors, the condensate in the lines can become contaminated over time. Condensate is contaminated with oil and must be removed before entering the sewer system or the ground. Oil must be separated from condensate, and must be recovered and disposed of in an environmentally safe manner.

The role of air compressor water separator

The compressed air enters the water separator through the curved inlet, and then the specially shaped guide vanes ensure high-speed rotary motion and force the compressed air to make a circular motion. After the resulting centrifugal force guides the water droplets to the outside of the filter housing, the water droplets flow downwards into the collection chamber due to gravity. In the water separator, a specially designed standpipe prevents the transfer of particles into the upward swirling flow of compressed air, which has mostly been cleaned of condensate. An innovative water separator rectifier directs the compressed air to the outlet with minimal flow loss.

Factors to Consider When Purchasing an Air Compressor Water Separator

Choosing the best water separator for your air compressor is no easy task. There are various makes and models on the market, so before parting with your hard-earned money, it takes some digging.

air inlet

The air inlet size of the air compressor separator filter is very important. Port sizes are available in various sizes such as ¾ inch, ⅜ inch, etc.

filter element

Filter elements should be of high quality for optimum durability. You need to check this feature in the product you want to buy before you can complete the transaction.

drainage quality

After the filtration process, the filter needs to be emptied. An air compressor water trap with high quality drainage will make this process easier and more efficient.

Pressure endurance

The working pressure of the filter will determine its load capacity. The best compressor water separator is useless if it cannot handle the compressor load, so this is an important consideration. For example, an air line water separator with a maximum working pressure of 150 PSI will have a greater pressure load capacity than a product with 100 PSI.


Several different materials can be used. Metal can be used, but it doesn’t have the benefit of seeing through. If the material is glass, then you can use the glass display to check the moisture content inside and know when to completely drain the water.

drainage system

Once you’ve stopped water from getting into your air tool, you’ll need to get rid of it. There are different types of drainage systems as they can be manual, semi-automatic or fully automatic.

  • Manual – This is a system that you will need to operate yourself when the water level starts to get high. When using this type of drain, you must remember to empty the tank regularly. This should be done after each use (or daily) or up to weekly.
  • Semi-Automatic – These work well for many people and save you from the hassle of draining your system. They usually empty when there is no pressure. Once the pressure builds up, the drain will automatically close.
  • Automatic – With this type of drain, it drains itself once the water has passed a certain point. This is usually when the bowl is about 50% full. Once this threshold is reached, the float will be released and the water will be drained from the system.

If you’re going to be using it for a long time, get a sturdy one with an automatic drain. This will prevent frequent emptying, which may reduce the effectiveness of the process.

ambient temperature

Ambient temperature may also be another consideration for your device. This will examine the water separator’s ability to handle exceptionally high or low temperatures. This isn’t usually a problem, but it might be worth checking if you work in hot or cold environments.

Final Note

In the end, it’s all about protecting your investment in tools and other uses of compressed air. The goal is to prevent water, oil and other contaminants from migrating down the system.

frequently asked questions about air compressor water separator

Inside your air compressor, you’ll find an internal water separator. An internal separator separates the water from the oil that remains inside the compressor. This oil is used to lubricate the rotating screw and other internal parts. In addition to this internal component, you will need to use an external water separator.

External contaminants such as water vapor and dust get mixed into the hot oil during the compression process. Once the air cools down at the end of the compression process, contaminated condensate is created. If this moisture collects anywhere in the distribution system (primarily the air receiver, filter bowl or moisture separator), the condensate will enter the compressed air system and cause equipment damage and ruin the end product. Due to the unavoidable costly and ugly by-products of using compressed air, a water separator is necessary and beneficial for any compressed air operation.

Water separators remove the oil by separating the water and oil from the compressor condensate before it can be properly treated to prevent it from entering wastewater. Most separators involve multi-stage filtration and adsorption principles. The different filters usually consist of fibers to absorb the oil (first-stage filter) and activated carbon to clean the condensate (second-stage filter). The oil separated from the water in the compressor is used to lubricate the rotating screw and other internal parts. At the end of this process, the water remaining in the system will be free of contamination and can be disposed of safely without concern for environmental hazards.

When the air pump compresses the air, it heats up. In an air receiver, when you use compressed air, it cools, and any water vapor in the compressed, heated air condenses inside the air receiver and collects at the bottom.

The water will eventually corrode the tank and potentially travel down the air hose and into your tool.
