According
to properties of fibrous materials, RF use different ratios of
fibrous materials to produce various air filter materials which
made by multilayer or monolayer forming and one side or two-sided
gluing, satisfy different requirements of clogging capacity and
filter efficiency. Air permeability and filter fineness are
considered for choosing air filter papers. Our air filter papers
can meet needs of producing various of air filters in the market,
and can be used for applications of trucks, cars and passenger cars
of heavy and light type.
