Buyer’s guide: Best Water Separator for Air Compressor
There is no doubt a water separator is a piece of important equipment for air compressors and air tools. But purchasing one is not like picking books off the shelf. You must also understand that not all water separators fit air compressors.
As such, you must look for a perfect fit for your equipment and air tools. This is why it is important to do some basic research before making any purchase. We have drawn up this buyer’s guide to help you make an informed choice.
Following this guide religiously will help you choose a unit that is functional, durable, reliable and versatile. Here are things you must consider before purchasing the best water separator for the air compressor.
1. Flow rate – Choosing the right water separator or air filter will depend on the maximum capacity of the air compression system. Capacity is usually calculated in CFM at 100 PSI.
2. Operating pressure – For every water separator, there is a minimum and maximum operating pressure of the unit. Water separators are measured are rated at 100 PSIG. Whenever there is an increase from 100 PSIG, there is a reduction in capacity. When pressure increases, the moisture load reduces thereby eliminating any strains on your compression system.
3. Ambient temperature – You have to determine the minimum and maximum operating ambient air temperature of the unit. Choose between high or low-temperature water separators.
Any ambient temperature that is above 100 degrees Fahrenheit may go beyond the maximum inlet temperature of the water separator.
4. Quality of bowl – Every water separator comes with a bowl to contain contaminants that cause harm to the air compressor. The quality of the bowl is of utmost importance.
Poor quality bowls may crack after a few times. Replacement bowls can also be difficult to get. As such, whenever you want to buy a water separator, ensure the bowl is either made from metal or polycarbonate.
5. Drain system – The water separator drain is a very critical part of the unit. You have to decide if you are going for a water separator with an automatic drain or manual drain.
Fidgeting with your water separator now and then can cause damage to the unit each time you want to manually drain the equipment. We advise you to go for a unit with an automatic drain system.
6. Transparent glass – Choosing a water separator with a transparent glass allows you to see the trapped content level. This is ideal since it will help you to know when to empty the container.
7. Metal guard – The glass must have a metal guard to protect the transparent glass from impact. A glass without protection can get damaged with a light impact.
8. Filter beads – Some of the water separators come with filter beads. The purpose of the filter beads is to indicate when to change the bowl.
The filter beads will turn will from blue to pink so you can get the bowl changed.
9. Pressure load capacity – You must endeavour to check for the water separator loading capacity to find out if it can cope with your air compressor load.
Also, check the output and input port to ensure they have the right fit for your air compressor.
10. Durability and sturdiness – Ensure that material used in making the water separator is a high standard to guarantee durability and sturdiness.
Units made from flimsy materials may break apart after some time. Look for something made from aluminium.
Frequently Asked Questions
1.How to change a fuel water separator filter?
Having a fuel water separator eliminates more than 95% contaminants that make injectors and fuel pumps to fail. When this tool is well installed, it minimizes exhaust emissions, repairs of injector or fuel pumps and reduces costly downtime. Contaminants and water affect the performance of air tools and engines.
If they are not properly removed, they cause the poor performance of your equipment. Constant inspection and maintenance can reduce such issues.
In case you have a worn-out fuel separator filter, below are the steps to follow to replace it.
Step 1 – release pressure
First thing you have to do is to remove the relay of the fuel pump. It is found right inside the relay box. Unscrew the gas cap to let you remove the remaining tank pressure.
Next is to turn on the engine and allow it to run for some minutes. Let the engine run till it stops. To completely remove the gas tank pressure, you will need to crank the engine several times until it is empty.
Now, you can re-attach the fuel pump relay.
Step 2 – Disconnect the hoses
Put a rag under the fuel filter to drain leftover fuel in the filter. Be very careful when working with fuel. Avoid smoking and don’t use inflammable materials.
Look for a pan to be placed under the filter. Next is to find a wrench to remove the fuel hose pipes. A flat screwdriver can do the job. Remove the hoses and drain oil that has found its ways into the pipe.
Step 3 – Disconnect the fuel filter and fuel water separator
Brackets are holding the fuel filter in place. Disconnect the brackets to remove the fuel filter by lifting it off its mount. Check the fuel water separator for deterioration.
If there is damage done to it, it makes sense to get a replacement. Check the hoses that are connected to the filter. If it is worn out, you should also consider a replacement.
Step 4 – The filter installation
Position the filter where it needs to be placed. Ensure that the flat side of it is the part facing the engine. Re-attach the brackets to the filter to secure it in place.
Next is to reconnect the hoses to the filters. Use clamps to tighten the hoses for a proper grip.
2. How does water get into air compressors?
Air compressors take in a lot of air. This air comes with plenty of water vapour in them. The water vapour is mixed up with the air. This occurs when there is humidity.
This water vapour begins to get denser after finding its way into the air compressor. Temperature change is one of the causes of this.
Gradually, the water vapour starts turning into water droplets thereby causing harm to the internal mechanism of the air compressor in different ways.
It is the same process that dust and debris find their way into the air compressor too causing the malfunctioning of the air equipment.
3. How to keep water out of air compressor lines?
Water and air compressors are never compatible. A compressor with air will also experience condensation. This is usually caused by humidity during the summer.
It does not matter if you are using the best air compressor in the world, moisture will always enter into the air tool. There are different ways to get rid of water from the air compressor lines. Some of these methods include frequently draining the air compressor.
This is usually a tough task since it has to be done constantly. Another way is to use the water trap to trap the moisture before it gets into the air compressor lines. But the best way is to use the air compressor dryer.
Using the air compressor dryer
The best way to get rid of dampness in your air tool is to make use of the air compressor dryer. Many of them come with absorbent little beads. The beads play an important role in the removal of moisture from the airline.
This type of air compressor dryer is called the desiccant air dryer. Its functionality is almost like the water trap filter system. But in the case of the desiccant dryer, there are three stages of filtration so you can have the purified air needed for your air tool.
Some of them come with two filters and a regulator. The first filter is the first point of contact for the contaminants. After the first filtration is done, next, is the second filtration in the second filter.
Then, the regulator regulates the air pressure to give your air tool the right pressure for you to perform the task without any problems. The dryer is mostly used in industrial settings.
4. How often to do you change the fuel water separator filter?
Answer: You don’t have to change the air filter often. How often you change the filter will depend on the level of humidity in the area where you reside and how you use the filter.
However, anytime you see a sign of breakage or distortion on the filter is the right time to change it but it is appropriate to change it at least twice in a year.
5. How to remove water from air compressor tanks?
Answer: air compressor maintenance is very vital for the proper functioning of the air tool. It helps to extend the life of the unit. One simple way to prolong the life of the air tool is to drain it of moisture. It does not matter if it is a 5 gallon or 110-gallon air compressor. The process is the same.
The first thing to do is to turn off the air compressor. Make sure it is unplugged from the outlet.
Next thing is to reduce the pressure to below 10 psi. Reducing the pressure means you have to pull that ring on the safety valve.
Ensure that you are wearing safety gear like the safety glasses. To deflate the air, shield the valve using one of your hands and pull the ring with the other hand. Continue to pull until you empty the tank.
Find the tank drain valve location. You can find it on the underneath of the tank. Then, drain moisture out of the tank by opening the drain valve. Close the tank drain valve when you are sure moisture has been completely drained.
6. Why is there a need to buy Oil-Water separator?
It is important to buy an oil-water separator to work with your air compressor if you don’t want your air compressor to get damaged by water, oil and moisture. As the process of compression starts, contaminants such as dirt, dust, water, hot oil and vapour all mixed.
This creates a lot of mess that could hamper the proper functioning of your air compressor and affect the process of compression. Having an oil-water separator minimizes this problem and makes your air compressor to work optimally.
7. How does pH affect the separation of oil and water?
pH measurement is about the acidity or alkalinity of water. pH is measured on a scale of 1 to 14 pH units. If the pH is 7, it is said to be neutral. When it is less than 7, it is known to be acidic and if it is greater than 7, it is alkaline. Generally, if the pH level is above 8.5 pH rating, the oil in the wastewater will chemically become a smooth mixture.
At this point, separation won’t work. One way to correct this is to make sure the pH level is lowered to about 6.8 pH.
8. Which substances create problems of odour in an oil/water separator?
Odour issue can arise with your water separator at any time. This is caused by bacteria in the water. The bacteria causing the odour are known as anaerobic bacteria. These bacteria grow without oxygen.
When these bacteria are present, they produce a foul smell like rotten eggs. This is usually noticed when there is no flow. You will need a good disinfectant to make the smell go away.
9. What are the types of dryers you can use to reduce dew points from compressed air?
Air compressors attract ambient air that comes with some water vapour. This can affect the functionality of pneumatic tools. To remove water vapour, compressed air dryers are always recommended.
Using a compressed air dryer prevents moisture and lowers dew points. Air gets drier when dew points are lower. If the aim is to prevent corrosion, the target must be to reduce dew point to -20 degrees Fahrenheit or even less.
There are different types of air compressor dryers to lower dew points. These are the types of air compressor dryers:
•Desiccant dryers – Desiccant dryers are also known as regenerative dryers. These types of dryers are mainly used in soaking up moisture from non-liquid desiccants such as silica gel, alumina or molecular sieves.
Moist air goes through the desiccant bed of the tower while the second tower dries it. This is important especially if there is a need for an application that needs maximum dew point performance which ranges between -40 and -100 degrees Fahrenheit.
When the low dew point is achieved, it protects against the freezing of the airline, especially in harsh weather conditions. Desiccant dryers are also very useful for applications that require a flow rate of over 100 standard cubic feet per minute (SCFM).
•Membrane dryers – At a dew point that is between 20 to 60 degrees Fahrenheit, the membrane dryers make use of the dehumidification membrane in eliminating water vapour in the compressed air.
Membrane dryers are quiet, needs no electricity to function, do not have moving parts, operate continuously and require no maintenance.
These type of dryers are perfect for an application that requires dew points of between 35 to 52 degrees Fahrenheit and flow rate of 600 standard cubic feet per minute (SCFM).
•Refrigerated dryers – These are the most commonly used dryers. They function by condensing water in a heat exchanger thereby cooling enough air to draw in and transport moisture and separate it from the air supply.
Not minding the fluctuations in inlet temperature, refrigerated dryers deliver constant dew points between the range of 38 and 50 degrees Fahrenheit.
10. What job does coalescing grip do in water separator?
Coalescing grip looks like a honeycomb. It is oil-loving. It pushes water with a lot of force in a back and forth motion and keeps a distance of ½ inch to the tank.
Oil droplets come together on the plastic medium and travel to the top before droplets are removed.
11. What is the meaning of condensation management?
Condensation management simply means the creation of constant production of water from the air compressor which usually involves the proper removal of moisture from the airflow. This stops the damage that could be done to expensive air tools and compressors.
12. What are the usually used hygroscopic materials in air compressor dryers?
Some of them are silica, calcium chloride, activated charcoal and calcium sulfate.
13. In what way do air compressors achieve their work?
There is usually denser moisture anytime the dryer provides high pressure into the compressed air. This causes the formation of water droplets which is eliminated by the dryer. Also, the air is purified during the process of releasing the pressure.
14. Does my air compressor need a water separator?
It is a must to use a water separator with your air compressor if you want the air tool to work perfectly without any hindrances since moisture can hamper the functionality of the air compressor.
15. How do I mount my water separator on the air compressor?
When mounting your water separator on the air compressor, you must ensure there is a minimum of 20 feet gap between the two units.
The gap between the two units allows for the dropping and cooling down of moisture. The cooler it gets, the more the condensation will be filtered from the tunnel of the air compressor.
Mounting the two units close to each other makes trapped vapour to get stuck inside the air compressor with no time to drop and cool the vapour to turn to water.
There is no doubt this article is more than enough for you to make up your mind on the best water separator for air compressor. They are some of the best water separators you can found anywhere in the market.
Any of the ten products can effectively save your air tool from impending damage and malfunctioning.
