The most important role of the air compressor filter in the air compressor system is to filter the role of moisture impurities, if we install it improperly, it will affect the quality of the compressed gas, so in order to ensure the quality of the compressed gas, what do we need to pay attention to when installing?Let's explain it to you.
1. Before installation, we should carefully read the product instruction manual and determine the installation location of the productPrecision degreasing and deodorizing filters should be equipped with corresponding filter driers.
2. The general installation position of the precision filter is the outlet end of the screw air compressor gas storage tank, and the effect is better when the compressed air temperature is close to the outside temperature.
3. Note that the interface of the air compressor filter is a pipe thread or flange, and the connection should maintain its sealing performance to avoid the deviation caused by pinhole leakage. Be sure to keep the filter installed vertically, and leave enough space under the filter to facilitate subsequent maintenance of the filter and automatic drain valve.
4. In order to facilitate maintenance, it is not necessary to cut off the air system of the screw air compressor, but the filter can be isolated from the system and depressurized. At the same time, it should be ensured that there is a gas release valve between the two isolation valves to facilitate maintenance, and reduce the pressure in the pipeline to atmospheric pressure during maintenance. If compressed air with a final filter is not permitted in some applications, a second filter should be installed on the bypass line.
Extended reading: What are the misunderstandings of the use of precision filters for air compressors?
Many people will fall into a misunderstanding when using screw air compressors, that is, the higher the accuracy of the air compressor filter, the better, in fact, this idea is wrong, not that the higher the accuracy of the filter, the better. In fact, the best air compressor filter is the air compressor filter that is suitable for your own use.
The accuracy of a filter generally refers to the diameter of the maximum solid particles that can be blocked by the air compressor filter. The higher the filtration precision, the smaller the diameter of the material that clogs the solid particles, and the easier it is to be clogged by large particles. Therefore, in the selection of air compressor filters, high-precision air compressor filters cannot guarantee filtration efficiency (which is related to permeability, which is the most important criterion to measure the quality of air compressor filters), and will also affect the service life of the filter. Therefore, we should choose the filtering precision according to the object of the filter and the purpose achieved.
When choosing an air compressor filter, there is a misunderstanding that the average person thinks that choosing a filter with the corresponding accuracy according to the required air quality can meet the requirements and save a lot of costs. In fact, the required air quality is determined by the processing accuracy of a single air compressor. And due to the excessive load, the high-precision filter element will quickly clog, speeding up the frequency of filter replacement, which will increase the cost in disguise. Therefore, when carrying out maintenance, the engineer should reasonably recommend the manufacturer to use the appropriate filter according to the actual situation, which not only minimizes the cost, but also should use the machine reasonably.
