The air filter of the air compressor system is the first barrier of the screw air compressor. The quality of the air filter is very important. If the quality of the air filter is not good, just like a human, the disease will be imported from the mouth. Poor filter quality will cause customers to waste a lot of electricity bills, and will directly affect the service life of oil, oil filter, oil, and bearings.

However, the quality of the air filter is precisely the problem that is most easily overlooked among the users of screw air compressors. Many people do not pay attention to the quality of the air filter. After the air compressor failed, they knew how bad the inferior air filter was, and he still didn't know what caused it, so he only knew that the air filter should be replaced.

The quality of the air filter is not simply a matter of price, nor is the more expensive the better, but usually the price of a good quality air filter is relatively higher, but it will not be too far apart. The price of the filter will be about 20-30% higher, and the price of the air filter with high-quality iron cover will be about 40-50% higher), the most important thing is to learn how to distinguish the quality of the air filter in order to get good quality, and the price is not special. High air filter, screw air compressor air filter quality is good or not, mainly depends on three aspects:

1. Waterproof performance
Everyone knows that the air contains a lot of water, especially in rainy days. The water content in the air will be higher. Once the air filter has poor waterproof performance, the air filter is easily damp, and the air filter will affect the air when it is damp. The compressor is inhaled smoothly or even blocked, and customers will waste a lot of electricity bills.

2. Filtration accuracy
If the filtration accuracy is not high, a large amount of slightly smaller dust impurities will be sucked into the screw air-torque machine, which will affect the service life of the oil, oil, oil filter, and bearings.

3. Air permeability
If the air permeability is not good, it will affect the unblocked suction of the screw air compressor, and it is also easy to block, and customers will waste a lot of electricity bills.

To test the quality of the air filter, we mainly start with the following three aspects:
1. Water detection, this is also the most critical and the simplest way to distinguish. For the inexperienced, water is the best way to detect the quality of the air filter. Put the air filter flat on the ground or on the table, on the filter paper. Sprinkle some water:
(1) If the filter paper seeps into the water within 5 minutes, it is an air filter made of cotton pulp paper and absolutely cannot be used. This kind of product is mostly produced in Hebei. A few of this kind of products are cheap in the screw air compressor industry. People use.
(2) If the filter paper that seeps into water within 2-5 hours is made of low-grade wood pulp paper, it can be used, but it will affect the scavenging efficiency of the screw air compressor (more power consumption, less air pumping), because this filter paper The price of the air filter made is relatively low, and it can also be used on a screw air compressor (more power consumption and less air, which is a waste of customer’s money), so now the air filter of this kind of filter paper in the air compressor industry is the mainstream. Most screw air compressor shops use this kind of filter paper for air filtration.
(3) If the filter paper only seeps in within 12-15 hours, it is a decent filter paper (mid-range filter paper). Generally, domestic screw air compressor manufacturers with better quality use the air filter of this type of filter paper as the original factory consumables.
(4) If the filter paper does not seep in for 24 hours, it is definitely a premium product (high-end filter paper). Usually, high-end machine manufacturers use the air filter of this type of filter paper as the original consumables.

2. Look at the light to see if the filter paper is uniform and the light transmittance is good. See if the surface finish of the filter paper is good. The filter paper is even and meticulous under the light. The light transmittance is good, and the surface finish is good. A simple method of identification requires a little experience).

3. Look at the depth of the filter paper and the number of folds. If the filter paper is deep and the number of folds of the filter paper is large, it means that the air filter has a large filter area, and the air filter has a large filter area, and the air permeability will be better.
It is not particularly difficult for air filters to achieve good waterproof performance. As long as high-quality wood pulp filter paper is used, the requirements can be met, but the production cost will be slightly higher. The real difficulty is not only to meet the filtration accuracy, but also to meet the air permeability. It is a real good air filter that can meet the requirements of these three aspects at the same time.

Finally, I hope everyone should be diligent in cleaning the air filter, not only to better protect the screw air compressor, but also to save electricity (dust attached to the surface of the air filter will affect the smooth suction), and the environment is particularly harsh It is best for users to clean the air filter once a day, replace the air filter in 500-800 hours, clean the air filter once in 3-7 days for customers with medium environment, and replace the air filter in 1000-1500 hours, customers with good environment! Replace the air filter every 500-2000 hours.
