Air filter of air compressor

The quality of the air filter is not simply a matter of price, and the more expensive the better, but usually the price of a good quality air filter is a little bit higher, but it will not be too far apart. (High-quality PU glue The price of the air 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 the good quality and the price. It is not a particularly high air filter. The quality of air filter 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. The water-proof performance of the filter is not good, the air filter is easy to be damp, once the air filter is damp, it will affect the air compressor to inhale smoothly, or even block, and the customer will waste a lot of electricity bills. 2. The filter accuracy, if the filter accuracy is not high, A large amount of slightly smaller dust and impurities will be sucked into the air compressor, which will affect the service life of the oil, oil, oil filter, bearing, etc.
2.Air permeability, if the air permeability is not good, it will affect the smooth suction of the air compressor. , It is easy to be blocked, and customers will waste a lot of electricity bills.

The quality of the air filter is mainly measured from the following three aspects.

First, water testing. This is also the most critical and the simplest way to distinguish.
For those with no experience, water is The best way to check the quality of the air filter is to place the air filter flat on the ground or on the table and sprinkle some water on the filter paper.
1.If the filter paper seeps in within 5 minutes, it is made of cotton pulp paper. Air filter is absolutely unusable. This kind of product is mostly produced in Hebei. This kind of product is used by a few people who are greedy for cheap in the air compressor industry.
2.If the filter paper seeps into water within 2-5 hours, it is a low-end product. Wood pulp paper can be used, but it will affect the air compressor efficiency (more power consumption, less air), because the air filter made of this kind of filter paper is relatively low in price, it can also be used on the air compressor (consumption More power and less gas, it’s a waste of customer’s money, it’s none of your business, haha), so now the air filter of this kind of filter paper in the air compressor industry is the mainstream, and most air compressor shops use this kind of filter paper
3. if the filter paper only seeps in after 12-15 hours, it is a decent filter paper (mid-range filter paper), usually a better quality domestic machine factory uses the air filter of this type of filter paper as the original 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 air filters of this type of filter paper as original consumables;

Second, look at the filter paper in front of the light Whether it is uniform and the light transmittance is good, see whether the surface finish of the filter paper is good. The filter paper is even and detailed under the light, the light transmittance is good, and the surface finish is good, indicating that the filter paper has a good filtration accuracy and good air permeability (this simple identification method requires a little Experience).
Third, look at the depth of the filter paper and the number of folds. If the filter paper is deep, the number of folds of the filter paper is large, indicating that the air filter has a large filter area, and the air filter has a larger filter area, and the air permeability will be better; the air filter should have good waterproof performance. Not special Difficulty, as long as the use of high-quality wood pulp filter paper can meet the requirements, 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, and the three requirements can be met at the same time. Really good air filter
Finally, I hope everyone reminds customers to be diligent in cleaning the air filter, not only to better protect the air compressor, but also to help customers save electricity bills (dust attached to the air filter surface will affect the suction Unblocked), users in particularly bad environments are best to clean the air filter once a day and replace the air filter in 500-800 hours. For customers with medium environment, clean the air filter once in 3-7 days and replace the air filter in 1000-1500 hours. Customers with good environment Replace the air filter every 1500-2000 hours.
