air filter c1250 size H134*119
Judging from naked eye observation, high quality air filter c1250 has the following characteristics:
1. Uniform folding number, no obvious deformation, high folding height, large dust capacity;
2. The filter paper material is smooth and has no obvious odor;
3. The rubber cover air filter in the high quality air filter is moderate in the soft and hard of the rubber cover. The fitting degree is good when installing, and it is not easy to deform and prevent dust from going in from the gap.
4, high quality air filter in the iron cover air filter, cover processing precision is high, installed in place.
From the perspective of technology-driven production:
1, filter paper is a key part of the filter element, the first thing to choose the right filter paper: such as the air filter paper of oil injection screw machine, international brands such as MANN and DONALDSON filter paper permeability is about 110-160, many domestic choose about 500, which relatively reduces the pressure difference, is not easy to fold, but can not ensure the filtration efficiency.
2, choose the appropriate polyurethane foam material: good flexibility, good resilience of the end face, with the temperature change, stability is still very good, compression is not large, size and air filter assembly precision coordination, prevent short circuit intake.
3. The origami process of air filter c1250 is one of the key links in the production of air filter. The intervals between each layer are regular:
Prevent the filter paper from sticking and folding - improve the ash capacity of the filter paper;
Adhesion of filter paper - in the environment of high humidity, the ash capacity of filter paper will be greatly reduced;
Test results - Service life increased: 50%.
