How to judge the quality of the air filter?(Series 1)
Whenever a combustion engine is designated?for equipment drive or machine.An filtration is necessary.
The basic element of each filter is a filtering septum made of paper or non woven fabric.
Engine filters contribute to the good functioning of the engine, limiting wear and damage caused by impurities and small particles. Efficiency in filters is based on the filtering power and duration.
To preserve the important function of filtration system it is recommended to check and replace filters every six months or a year.
So how to judge the quality of air filter?
Today Susan will show you how to determine the quality of PU air filters.
1.Appearance:Very smooth,No bubble, No scratches.
Standard size, the same to the original factory.(The most common way to cut corners is to maintain the length and width of the filter and reduce the height. In this way, the filter can be installed normally, but it reduces the amount of dust, shorten the service life)
2.PU rubber：Another important element in the filter is to seal. It is housing with polyurethane foam.
You see the PU rubber, it has good elasticity, has moderate hardness, it will not crack in hot and cold weather.
Filter paper：Filter paper, the thickness of the filter paper is uniform, high filtration accuracy.
We use standard gram filter paper 125g/㎡-130g/㎡,?

The folding number of filter paper is also dense and sufficient
The filter is not easy to deform, good stiffness and rupture resistance, high dust capacity.?
And the air intake volume is above 300L/㎡/s
Hot melt adhesive: under the working condition of 125 degrees, no softening, no deformation(Poor quality hot melt adhesive will melt at 70 degrees, resulting in filter deformation)
In addition, PU air filters can be of various types
Ranging from round and paneled
Some filters are equipped with additional filters: felt or sponge to increases the life of the filter
