Filter materials are divided into three grades according to filtration effect:
<
Grade: lowest filtration efficiency

Level: lowest filtration efficiency

Level: lowest filtration efficiency

For example:

means: can be used to protect non- Oily particles

Indicates: the filtration efficiency can reach the minimum

The filtration efficiency is tested in micron particle size, and the flow rate is liters/minute
