Things to Consider Before Buying Water Separator for Air Compressor

A water separator is a very advanced technology that has no alternatives nowadays. Because the use of an air compressor is increasing day by day. The most alarming matter is, every compressor machine produces wetness during operation. We are going to discuss the best water separator for air compressors. The description can be found below,

Inlet & outlet valve

The water separator consists of two basic valves to be functional during the high air pressure. The mechanism is to let the high pressurized air into the valve and let out the air by the absorption process. The inlet valve is used to let the water inside by a pneumatic force.

The outlet pipe gets activated when the process of air reduction is completed entirely. The air pressure gets increased after passing through the inlet valve and sometimes becomes warmer. Your water separator may contain an external cooler to cool down the filter.

Durability

Product durability is the main key for customer satisfaction to be increased. In the air compressing situation, you won’t be able to find another choice. The air pressure of an air compressor is usually having a range between 6 to 9 bar. As a result, you are going to need a high hardness material.

The outer side of the product is produced by casting properly with a mixer of a different metal. The mixture is called an alloy. The mixture consists of lightweight material like aluminum, zinc, copper, etc. The tensile and compressive load of the alloy is high enough to take the high air pressure easily.

Moisture Drainer

Our mentioned water separators consist of a single drainer. The drainer is used to maintain the water absorption level while the air passes through the water separator. The drainer is attached to the middle of the air barrier and the included bucket. You can also attach it externally if there isn’t any included.

A drainer is included with the product according to your needed measurement. The general size differs for the outlet size of your air compressor machine. So be careful before buying this product.

Mounting Features

A water separator can be mounted in different places. It completely depends on the bowl that comes with the product. Before mounting, some of our mentioned products need to be attached to the bucket first. Then you can mount the bucket to the wall or any suitable place for the water separator.

Measuring Equipment

To measure the level of absorbed water, you will need a meter. The water separators consist of an inbuilt water level measurer. There is also an indicator that is used to indicate the water beyond the safety range. The measurer has three levels of indication. The red, yellow, and green indicators show the real-time water absorption measurement.

Bottom Adjustment

The bottom of every product that we have mentioned, consists of a screw. The screw has great importance, as it helps to adjust the pressure taking the level of the inserted air. The air compressor has high pressure creating ability. But that pressure will destroy the water separator. To protect the product from being destroyed, the pressure level is minimized by the screw.

Cost

It is the most important factor. Our described product possesses a logical cost based on the mechanism. If you want high air pressure taking ability then you may go for the pricey one.

Frequently Asked Questions (FAQs)

Do the water separators consist of drains?

Answer: I don’t know why they wouldn’t consist of drains. The drain has a very unique purpose to do a particular job. The conducted water by the air compressors is directly gone through the water separator. The drain is the only component that absorbs the remaining water from the air. All of our mentioned products consist of this feature.

Can I use the machines to use as an oil separator?

Answer: No, it is not possible to separate oil from the air by the water separator. The oil has a greater density than water. So, the oil is heavier than the water. Also, the stickiness factor is a big issue, as is the inner surface of a water separator made of metal. So, the machines are made to do only water separation with a particular type of product.

What are the general fitting measurements of the water separators?

Answer: Usually, the machine can be fitted to the opening gate having 1/2″ and 3/8″ fittings. Although the device can be fitted to any kind of custom measurement. A particular measurement has a little flexibility error while setting up. 5/8” setting needs to be customized by the seller while you approach to buy.

Can I be able to mount those products with a wall?

Answer: Yes, the products can be mounted with the wall. To mount those products with a wall you need a bucket that needs to be attached to the wall first. However, some of the products need an external component for the attachment. You may need to buy an external filter that will help the bucket to attach with the wall and mount the device.

Can I empty the included bucket from the water with those water separators?

Answer: No, you cannot reduce the water from the bowl included with the product. The bowl is used to store the separated water from the air separator device. The differentiated water doesn’t have access to the main air compression line. As a result, the segregated water cannot be reduced by the air pressure unless you manually reduce them.

Do I need to change the blast beads often?

Answer: Yes, you may need to change the blast beads often of those products. It depends on the air compression machine. As the air compressors have different power product capabilities, the beads may not be compatible with your machine. The beads mainly take air pressure and help to separate water. So, ask the seller for the details about it before buying it.

Do the water separators work automatically?

Answer: Yes, the device itself is pretty much efficient with automatic action. But you have to manually set the device up. You have to connect the inlet pipe to the air compressor and the outlet pipe to the water separator. The water separator will do the rest. Also, the bucket under the device is not automated and needs to be cleaned up manually.

Final Verdict

The presence of water in any pneumatic job is too risky. Because it may become responsible for any kind of breakdown of the air compressor. In the entire post, we have tried to show you the potentiality of a water separator. As there are many brands available, finding the perfect seven products was pretty much challenging.

If you have read the whole post, you know the specific factors that can make a difference between the products. When you will go to the market, these factors will help you to choose the right one. Also, you can inspect the customer satisfaction level for each product to justify their offered features.
