Compressed air filters are specially designed to solve compressed air systems with heavy oil, water and dust. Compressed air filters are essential filtration devices for improving the quality of instrument gases in factories and laboratories. The brand filter has 12 new equipments of patented products such as top cover, middle tray and bottom tray. Two aluminum barrels are connected to form a first filter chamber and a second filter chamber, the lower end of the lower case is connected to a drainage device with a joint, and the drainage device is provided with a floating ball.

A special filter material is inserted into the filter, so that water, oil, rust and various other elements in the air are completely filtered throughout the compression process, and the filtration efficiency reaches 99.9%. Compressed air filter properties:

100% removal of particles larger than 5 microns

Filters 99.9% of oil droplets and suppresses oil mist concentration to 0.1ppm or less

There is no water droplets, the pneumatic dew point is greatly reduced, and the same effect as a refrigeration dryer can be obtained.

How compressed air filters work:

1. Introduce compressed air containing contaminants such as dust, oil, rust and water into the first stage filter unit of the compressed air filter.

2. When compressed air passes through the first stage cylindrical mesh filter element, a coalescing effect occurs where larger particles are adsorbed onto the filter material and water condenses into larger droplets. 3. Once in the separation chamber, the compressed air velocity slows down, so the particles accumulate again and the water mist condenses again into the honeycomb waterfall.

4. Water laden with dirt particles flows along the bottom to the drain and is discharged through an automatic or electric drain valve.

Five. More than 95% of water droplets, oil and large particles in the compressed air are filtered by the first filter element and the filtered compressed air from the first stage enters the second stage filter element.

6. When the compressed air passes through the second stage fiber filter made of special cotton, thousands of small vortices are generated and the compressed air is accelerated by tens of times. The center of the vortex becomes like a tornado, creating a vacuum. Water droplets that cannot be completely filtered by the first-stage filter are repeatedly evaporated, converted, and filtered, and at the same time, particles up to 5 microns are completely removed by the second-stage filter. 7. Ensures the normal operation of air equipment and prolongs the life of pneumatic equipment Two-stage filtration can achieve clean and dry compressed air without dust, rust, oil and water droplets. 

Compressed air filter installation principle:

In order to maximize the effect of the product, please select the appropriate installation position according to the purpose of the site.

1.Please connect the air inlet and outlet correctly according to the direction indicated on the product and pay attention to the vertical installation.

2. To solve the problem of oil and water in branch lines and terminal equipment, it should be as close as possible to the terminal equipment. Usually within 7.5 meters. 3. When installing the product in the main line of the air compressor station, please keep it at least 10 meters away from the air compressor exit. The lower the temperature of the pipeline, the more suitable for installation. If the installation site air inlet temperature is above 60°C, it is recommended to install an aftercooler before the filter.

The need to install a compressed air filter

Compressed air is often used as an energy and power source because it is safe, flexible and readily available. However, in order to reduce running costs and improve work efficiency, it is necessary to purify this compressed air. Removing contaminants such as water, water vapor, waste, oil mist and exhaust gases from compressed air can improve energy efficiency.
