How Does A Water Lubrication Air Compressor Work?

The working principle of water lubricated air compressor is to use piston or screw to compress air.

The compressed air is then passed through a water bath, which lubricates the moving parts of the compressor and removes any contaminants. The clean, dry air is then stored in a container ready for use.

Advantages Of Oil-free Water Lubricaion Air Compressors

Don’t Contaminate Air

Certain industries require completely clean air which is why oil-free water lubrication compressors are chosen. The food and beverage, electronics and medicine industries do not tolerate air contamination regarding their products. 

Oil Free Compressors Cost and Weigh Less

An oil free water lubrication compressor has less parts than an oil lubricated compressor so therefore is lighter in weight, as well as cheaper in cost. Their designs are often simpler too.

Oil Free Compressors Are More Efficient

The oil free water lubrication compressors are more efficient than oil-lubricated air compressors. This is because water is a better lubricant than oil, and it does not need to be changed as often.

High Quality Water Lubrication Air Compressor

A water lubrication air compressor is an oil-free type of compressor that uses water as its primary lubricant. These compressors are used in a variety of industries, including pharmaceutical and food processing.

Water lubrication air compressors provide clean, high-quality compressed air without the pollution risks associated with oil-lubricated equipment. In some applications, such as pharmaceuticals, food and beverage production, where air purity standards need to be met, even trace amounts of oil pollution can cause products to deteriorate or damage production equipment.

There are several advantages to using a water lubrication air compressor, including cleanliness and energy savings. They are also more compact and easier to move than lubricated air compressors, making them a popular choice for smaller applications.

Let’s Learn  Something Together

This type of compressor is often used in industrial settings where there is a need for a high-pressure air supply.Water lubrication air compressors offer a number of advantages over other types of air compressors.

Oil vs. Oil-Free Air Compressors

The most obvious disadvantage of using oil-lubricated compressors is the risk of oil contamination. Oils used to lubricate, seal, and cool machines leave a certain oil content in the compressed air that must be removed by separation or filtration. In industries where air purity is critical (especially in sterile environments), even the smallest droplets of oil are at risk of contamination.

The biggest argument against oil-free compressors is their relatively short life expectancy. Again, this may have been the case then, but the longevity of today’s oil-free compressors is no longer an issue.

Significant advances have been made in oil-free technology, allowing oil-free compressors to operate at lower temperatures and last longer. In addition, they require less maintenance than oil compressors.

How To Choose A Water Lubrication Air Compressor?

When selecting water lubricated air compressor, the following factors need to be considered:

Compressor size. You need to choose a compressor large enough to meet your needs.
Compressor pressure. You need to choose a compressor that can provide the pressure you need.
Compressor flow rate. You need to choose a compressor that can provide the flow you need.
Compressor noise level. You need to choose a compressor that is quiet enough to meet your needs.
The price of compressor. You need to choose a compressor that fits your budget.

What Causes Moisture in Compressed Air?

Humidity is an inevitable byproduct of compressed air. The amount of moisture in compressed air is directly related to:

The amount of water in the intake (humidity level), and
How much air is compressed.
All air contains some amount of water vapor. The water held by air varies with temperature and pressure. The higher the temperature, the more water the air can hold. This is why humidity tends to be higher in warmer months than in winter.

How To Maintain A Water Lubrication Air Compressor

To maintain a water lubrication air compressor, you need to do the following:

  • Clean the compressor regularly. This will help to prevent the build-up of contaminants, which can damage the compressor.
  • Change the water in the compressor regularly. This will help to prevent the build-up of bacteria, which can also damage the compressor.
  • Inspect the compressor regularly for any signs of wear or damage. This will help to prevent serious problems from occurring.

Applications Of Oil-Free Water Lubrication Air Compressors

For the pharmaceutical industry and many other medical applications, cleanliness is critical to product quality and performance. During the manufacturing process, contaminants such as moisture or grease can affect the quality of products.

Pharmaceutical Industry

Like the pharmaceutical industry, the food manufacturing industry requires zero pollution. Virtually every food manufacturer has its own risk management guidelines that specify acceptable levels of contamination with oil, water and other particles.

Food Industry

Water lubricated oil-free screw air compressors are used for cleaning printed circuit boards (PCBS) and other similar applications. This water-injected oil-free screw air compressor provides dry, clean compressed air that protects fragile instruments.
