Select the protection level and then view the dust in the environment:

If only harmful gas, then the general tank choice can meet the requirements; If it contains dust, then the tank should be integrated. According to the filter level, the comprehensive filter can confirm the performance level of filter dust:

P1: general capacity filtration efficiency: ≥ 95.0%;

P2: medium capacity filtration efficiency: ≥ 99.0%;

P3: higher filtration efficiency: ≥ 99.99%.

The higher the dust level of the filter tank is, the smaller the diameter of the filter particles is, and the higher the performance of the filter is.

In short, the way to select a can is to look at the type of protection, look at the level of protection, and see if there is any dust.
