-
In
the "A" series, the same continuous porous material with a high pore
density as in the W and D series is made water-resistant and does not
soften, even in water, retaining its original shape. Various pore
diameters are available. All of the products are used as filter, sound,
absorber, and absorption/impregnation medium for printing ink or other
various oils. AION Air Filter is an application of the "A" series sponge
sheets to a unit type air filter. It is a medium to high performance,
