A good air filter must have several dimensions to check:
1. Strength. The air filter industry does not have accurate industry reference standards, and the comprehensive evaluation factors are too many and complex, requiring disassembly and experimentation, which is not suitable for understanding. So I think the strength of air filter manufacturers is more important. Poor manufacturers will incorrectly label some technical parameters. For example, cheap air filters are everywhere. Do we still need to see it after we buy it? So don't look for bargains from bad manufacturers. Basically, you can't take advantage of them.
2. From a visual perspective, high-quality air filters have the following characteristics:
1. Uniform folding times, no obvious deformation, high folding height, and large dust capacity;
2. The filter paper is smooth without obvious odor;
3. The rubber cover in the high-quality air filter is moderately soft and hard, providing a good fit during installation, not easy to deform, and preventing dust from entering through gaps;
4. The iron cover air filter in the high-quality air filter has high processing accuracy and is installed in place.
3. From a technical and production perspective:
1. Filter paper is a key component of the filter element. First of all, it is necessary to choose the appropriate filter paper: for example, the air filter paper of the oil injection screw machine, and the air permeability of international brands such as MANN and DONALDSON is around 110-160. Relatively speaking, the pressure difference is reduced and it is not easy to fold, but the filtering efficiency cannot be guaranteed.
2. Select appropriate polyurethane foam material: good end flexibility and resilience. With temperature changes, stability is still very good, with a small amount of compression, and the size accurately matches the air filter assembly to prevent short circuits into the air.
3. The origami process of air filters is one of the key links in the production of air filters, with regular intervals between each layer:
Prevent filter paper from sticking - improve the dust capacity of the filter paper
Stickiness of filter paper - In high humidity environments, the dust capacity of filter paper will be greatly reduced;
Test results - increased service life: 50%
It is understandable that users purchase and replace equipment consumables to save maintenance costs, but not everyone can accurately judge product quality, which also provides opportunities for inferior products.
Through the above points, quickly identify and select high-quality air filters to ensure that the air entering the air compressor is sufficient and clean, avoid shortening maintenance cycles, machine damage, and other losses, greatly reducing overall operating costs.
