Air compressor filter

1Introduction to Air Compressor Air Filter

Air filter, also known as air filter or air filter screen, is commonly used in dust removal and filtration devices such as compressors, automobiles, and generators. It is commonly used in wire mesh, Raschig ring, paper and fiber material filter screens.

IIThe function of the air filter in the air compressor

When compressed air passes through the fiber filter made of special cotton in the second stage, thousands of small vortices will be generated, and the compressed air will be accelerated dozens of times. The center of the vortex is like a tornado, forming a vacuum state. Water droplets that have not been filtered out in the first stage will be vaporized, converted, and filtered again. At the same time, particles as small as 5um will be completely removed by the second stage filter, and particles larger than 0.5um will be completely removed by the third stage filter.

2. Clearly solve the high cost of fluid machinery material accessories, frequent malfunctions, and low equipment efficiency. The increase in labor intensity and other troublesome issues for workers has had a good effect.

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

4. Through combination design, it can achieve the function of a respiratory filter.

3、 Selection of Air Filter for Air Compressor

Shanghai Zhaokuo Purification Equipment Co., Ltd. provides inlet air filter assemblies for air separation units, centrifugal compressors, axial compressors, blowers, engines, and gas turbines.

One type is a box filter, with a primary size of 595 * 595 * 38 (23.4 "* 23.4" * 1.5 ") and a secondary size of 595 * 595 * 295 or 292 (23.4" * 23.4 "* 11.5") The material of the filter housing can be carbon steel or stainless steel, and the material of the filter frame can be aluminum alloy, galvanized frame, stainless steel, or plastic frame.

Another type is self-cleaning filter, with filter cartridge sizes including: diameter 320 * 660 (diameter 12.5 '* 26'), diameter 320 * 700, diameter 320 * 750, diameter 320 * 900, and diameter 320 * 1000. There are two types of composite filter paper, domestic and imported, to meet the needs of different equipment and filtration occasions.

In normal circumstances, the cleanliness of the air supply is determined by the air filter of the air compressor, and the front end of each air filter of the air compressor is designed to protect the rear end, in order to ensure the use time of the air filter of the air compressor and ensure its normal operation. When purchasing an air filter for an air compressor, it is necessary to consider all aspects of the air filter and choose the air filter that is suitable for oneself according to the actual situation. The selection principle is as follows:

1. Determine the filter characteristics of the air compressor air filter:

Mainly including filtration efficiency, resistance, penetration rate, dust holding capacity, filtration wind speed, and processing air volume. When conditions permit, high-efficiency, low resistance, large dust holding capacity, moderate filtering air speed, large processing air volume, easy manufacturing and installation, and low-priced filters should be selected as much as possible. This is an economic analysis that takes into account both one-time and secondary investments, as well as energy efficiency ratios, when selecting air filters for air compressors.

2. Analyze the properties of dusty gases in the air filter of the air compressor

The properties of dusty gases related to the selection of air compressors and air filters mainly include temperature, humidity, acidity and alkalinity, and the amount of organic solvents. Because some filters allow for use at high temperatures, while others can only operate at room temperature and humidity, and the amount of acid, alkali, and organic solvents in dusty gases has an impact on the performance and efficiency of air filters in air compressors.

3. Use an air compressor and air filter to accurately measure the dust content and particle characteristics of outdoor air

When selecting a filter, outdoor air is filtered and purified before being sent indoors. The effectiveness of multi-stage purification and filtration treatment is highly valued, so factors such as the usage environment, spare parts costs, operating energy consumption, maintenance, and supply of the air compressor air filter should be considered.

4. According to the indoor cleanliness and purification standards, select the appropriate combination of air compressor air filters and the efficiency of each level

For general indoor purification requirements, a primary filter can be used; If the indoor requirement is moderate purification, two-stage filters of primary and medium efficiency should be used; If the indoor requirement is ultra clean purification, three levels of purification filtration, namely primary, medium, and high efficiency, should be used, and the efficiency of the air filter of the air compressor should be reasonably and properly matched.
