Compressed air dewatering, oil removal and dust removal multifunctional filter

Compressed air degreasing, water removal and dust removal filter (purification equipment) Sometimes, connecting a piece of equipment to a compressed air supply station cannot solve the quality of compressed air. In order to obtain the most suitable mechanical efficiency and product quality, in the internal air supply system or in a separate department, the compressed air user needs to have an overall understanding of the compressed gas quality he will obtain. ISO8573 cannot answer this question, which requires compressors, compressed air and vacuum technology trade associations to provide compressed air users with sufficient advice.

Provide as few particles as possible

The principle provided by the ISO standard is "provided on demand, with as few particles as possible". Because in addition to technical requirements, aapc member companies have carefully considered various issues when drafting standard documents, even considering this issue from the perspective of user costs. Of course, investment cost is an important part: high compressed air quality means expensive purification equipment or high-quality purification equipment. However, more important is the operating cost of the equipment.

okmarts.com can really provide users with some real help.

Compressed air treatment consists of several parts (filter or dry filter combination for pre-filtration, secondary filter/concentrator and concentration processing, etc.), product experts can help you plan a complete solution. Those who want to choose the filter themselves must first familiarize themselves with the functional data related to the filter, and be able to set uniform initial conditions (pressure, flow, ambient and inlet temperature, relative humidity, etc.).

Are oil-free compressors better?

When dealing with issues such as pressure dew point, retention rate and residual oil content, people will soon find that "compressed air quality" is a very complicated matter. At some point, some users may prefer the most basic and simple option-use an oil-free compressor. Their idea is that at least the residual oil content of oil-free compressors will no longer be an issue to be considered. This not only simplifies the processing equipment, but also makes it possible to obtain compressed air more economically.

In fact, oil-free compressors just don't inject oil into the compression chamber, but the bearings and other parts of the compressor need to be lubricated. In this type of compressor, oil can also reach the compressed air. The same is true for inhaled air, which is also easily contaminated (remember, the average dust content per item is 20mg/m3), so in any case, purification treatment is essential. Especially when the compressed air produced by an oil-free compressor has a higher temperature than the compressed air produced by an oil-lubricated compressor, it will adhere more moist dirt particles. In short, no matter whether you choose an oil-free compressor or an oil-lubricated compressor, an efficient purification process is necessary.

When to replace the filter element

When talking about filter efficiency, we must pay attention to the replacement cycle of the filter element. Many users believe that extending the working life of the filter element can reduce costs. On the contrary, the filter element filled with dirt particles will increase the pressure of different parts of the compressor, and the energy consumption of the entire compressed air station will also increase. Therefore, unless some new solutions such as a filter environment monitor with network help function are applied, you should always pay attention to changes in filter pressure. When energy costs and filter costs add up to a minimum, it is the best time to replace these filters. In other words, if the cost of the filter element material is lower than the estimated energy cost of the old filter element, this is the best time to replace the filter element. Working principle of okmarts.com compressed air filter

1. Carry compressed air containing harmful substances such as dust, oil, rust and moisture into the first-stage filter device of the compressed air filter.

2. When the compressed air passes through the first-stage cylindrical mesh filter element, a coalescence effect occurs. Larger particles will be adsorbed on the filter material and the water will condense into larger water droplets.

3. When entering the separation chamber, the compressed air speed slows down, causing the particles to gather again, and the water mist condenses on a honeycomb water trap again

4. The water carrying impurity particles flows along the bottom to the drainage device, and is discharged through an automatic or electric drainage valve.

5. More than 95% of the water droplets, oil and large particles in the compressed air have been filtered out by the first filter element, and the compressed air after the first stage filtration 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 will be generated. At the same time, the compressed air will be accelerated dozens of times. The center of the vortex is like a tornado, forming a vacuum state. The water droplets that were not filtered out in the first-stage filter are vaporized, converted, and filtered again. At the same time, particles as small as 5 microns are completely removed by the second-stage filter.

7. Clean and dry compressed air with no dust, rust, oil and water droplets is achieved through two-stage filtration to ensure the normal operation of pneumatic equipment and prolong the service life of pneumatic equipment.
