Advantage of Air Fume Exactor for 20w Fiber Laser Marking Machine发布人:Berry      发布时间: 2019-11-06
3 layers filtration to ensure filtrate harmful material of the fumes completely,

to achieve room air quality standard, protect environment and people's health.

1) 1st layer called Primary filter for remove big particles/smoke/dust. 

2) 2nd layer called Medium efficiency F8 class filter to remove smaller particles/smoke/dust. (>=1Mircron).

3) 3rd layer called main filters, Include 1 layer activated carbon filter & 1 layer H13 class HEPA filter

to remove small particles, smoke and light smells.

I don´t know if 1+2+3 is in one block or only 2+3 is in one standard filter block - I need minimal the 2+3 block (primary filters I have).
