Material and characteristics
Purpose and usage
|
1.Primary filter cotton is mainly used for fresh air filtration, filtering ≥5μm particles and foreign bodies, large dust capacity, small resistance, cheap price, simple structure; |
|
2.Medium effect filter cotton is mainly used for spraying production line fresh air end and return air filtration, mainly filtering 1-10μm suspended particles. |
|
3.High temperature resistant, flame retardant filter cotton is made of glass fiber or other high temperature resistant, flame retardant materials, mostly used in high temperature fire environment. |
