Crew compartment high efficiency air filter paper

Crew compartment high efficiency air filter paper. The filter paper consists of a main filter layer made of alkali-free ultra-fine glass fibers with two to three different beating degrees or fineness, and a reinforcing layer coated with hot melt adhesive and compounded on both sides of the main filter layer. The filtration efficiency of this air filter paper can reach 99.99999% or more, the tensile strength exceeds 1666.7 N/m, and the filtration resistance is less than 420 Pa. The available critical filter materials for combat vehicles can also be applied to other relevant air purification devices.
