How to Choose the Best Air Compressor Filter

air line compressed air system

If you’re looking for an air filter compressor, it’s important to know what features are best suited for your needs.

The following are the most important things to consider when purchasing an inline water filter for an air compressor:

Material

The material in the filter will determine if it can purify water vapor in the air. If you want to remove water vapors from the air, your filter needs to be capable of doing so.

When you choose a filter with a metal mesh or aluminum material, you’ll get a more durable product. Plastic air filters are good if you’re on a budget.

Compressor Types

Make sure that your air filter is compatible with the type of compressor you’re using. If it’s a pneumatic or portable one, then most air filters will work just fine.

For larger, stationary compressors, choose a closer filter to the compressor itself so you will not have to worry about long hoses.

Micron Rating

The micron rating is an important factor that can determine if the filter will get rid of water vapors. If you want to remove liquid from the air, your filter needs to be capable of doing so.

That’s why when choosing a filter, you need to consider the micron rating of the filter. The lower the micron rating, the better it can catch water particles.

Flow Capacity

manual drain system air compressors

Another important thing to consider is the flow capacity of your filter. If you’re using an air compressor that’s powering multiple air tools, then the flow capacity will determine how fast it fills up.

The higher flow rate is better. Most portable or stationary compressors will be able to power one large tool at a time.

Air Inlet and Outlet

The size and shape of the air inlet and outlet are important. Make sure you choose a filter with an easy fit for your compressor.

Quick-release couplings will make it easier to connect and disconnect the combine.

Drain Type

If you want to prolong the life of your filter, then you’ll need one that includes a drain. The drain is for draining out the water in the filter so it does not develop mold or mildew.

There are 3 common types of drain: manual, semi-automatic, and automatic. Each has its own benefits.

Load Capacity

You might be using a portable or smaller compressor, but if you have multiple air tools powered by the compressor, then it’s important to choose one that can handle the load capacity.

If you’re going for a pneumatic one, go with a more powerful filter. If you’re planning to use larger air tools with your compressor, then your load capacity should be considered.

Durability

A durable filter is a great investment. Choose one made from heavy-duty material. Mesh air filters tend to be more durable while plastic tends to be less so.

Size

The size of the filter is important to consider because you’ll want one that’s easy to carry or store. Portable compressors are typically smaller, so your filter should be just as portable.

Frequency of Use

If you have multiple air tools running at once, then your filter needs to be up for the task. Choose one that can support high-end, high-volume air compression. The more you use your compressor, the better quality filter you should have.

If you follow these steps, you’ll find the compressor air filter that will suit your individual needs.

Types of Air Compressor

Compressors can be categorized into four main types:

i) Rotary Screw Air Compressor

This type of air compressor is ideal for those who need a good source of air pressure. It operates on two meshed motors, which are driven by a single motor and meshing helical screws.

ii) Reciprocating Air Compressor

Reciprocating air compressors are similar to the rotary screw compressor. It works by having a piston that moves up and down in cylinders with the crankshaft, connecting rods, and flywheel. This reciprocating action compresses the incoming airflow.

iii) Axial Air Compressor

This type of compressor is perfect for those who want a more compact unit. It operates on the same principle as the gas compressor, except it takes up less space because there are fewer moving parts that take up space.

iv) Centrifugal Air Compressor

This type of compressor is ideal for those who need a powerful tool. It can handle higher pressure and works by using a rotating impeller that absorbs the air from its surroundings.

In addition to these four types, there are other compressors that use a combination of two or more of these methods to create a hybrid compressor.

Types of Air Compressor Inline Filter

There are 6 types of air compressor inline filters:

i) Particulate Filters

ii) Activated Carbon Filters

iii) Coalescing Filters

iv) Cold Coalescing Filters

v) Compressed Intake Filters

vi) High-Efficiency Filters

How Does a Compressed Air Water Separator Work?

air filter compressor tank

To separate water from compressed air, you need an air compressor water separator and then pass it through a de-watering unit.

The process starts when you should filter out dust particles before compressing. After that, the suspended liquid droplets in the compressor should be separated by centrifugal force and then turned into liquid form (vapor converted back to liquid).

The compressed air should then pass through a coalescing filter, which removes any remaining trace of water droplets.

Finally, the air should go back into your air line filter after passing through an activated carbon filter for removing odor and disinfecting.

How Does a Water Trap for an Air Compressor Work?

clean and dry air filter

A water trap for an air compressor is a device that provides protection against water contamination. This device can also prevent freezing and corrosion.

It’s important to use such a device as it protects the air supplied to other equipment by removing moisture from the compressed air system.

This air filter unit separates moisture, oil, and oil vapor from compressed air by means of a cooling coil and an internal separator tank.

FAQs

Here are the most common questions that may come to mind while looking at the above article:

1. Where to Install Water Separator on Air Compressor?

The air compressor water separator should be installed between the pump intake and the storage tank. This ensures that the water is being separated from the air as it enters the tank.

As a result, there is no contamination between the environment and the cooling of the machine, which prolongs its life.

2. How to Keep Water Out of Air Compressor Lines?

There are many methods that you can use to keep water out of your air compressor.

First, always make sure that there are no leaks in the air compressor. Second, make sure that you purchase a model that lets you drain the water after every use.

Third, purchase air compressor water separators for your air compressor to avoid any problems in the future and ensure proper polishing and lubrication of the machine.

3. How to Drain Water from Air Compressor?

water separator compressor and air tools

To drain the water from your air compressor, make sure that you start with draining off the water reservoirs.

You can do this on a regular basis to prevent any future problems. Don’t forget, before draining it completely make sure to remove all four plugs, and after you are done removing them put them back on again.

The air compressor water separators will have to be emptied after every use.

4. How to Remove Moisture from Compressed Air?

To remove moisture in compressed air can be done in the following ways:

  • The tank is being drained.
  • A water trap and filter regulator is being used.
  • A refrigerated air dryer is being used.
  • A desiccant air dryer is being used.
  • A deliquescent air dryer is being used.
  • Air is dried through a piping system.
  • The cooling is done in a storage tank.
  • By absorbing moisture from the air.

5. Do I Need a Regulator on My Air Compressor?

The answer to this question is YES. If you are using an air compressor, you will need a regulator to regulate the air pressure.

The benefit of having one is that it will protect your air tools from any overpressure. A regulator can be attached to the main valve of an air compressor or added on later at any time.

This is definitely something that should never be done without because even a little bit of overpressure can cause irreparable damage to the machine.

6. Why Drain Water from Compressed Air Tanks?

It is important to drain water from a compressed air tank because it helps keep the machine running smoothly and prevents contamination.

If you fail to separate water from your machine, it will freeze. This can lead to damaged air filters, broken air tools, and valves. This ultimately leads to more downtime for repairs.
