KLENOW Self-cleaning Filter has a built-in high strength composite fiber nano air filter element with an air storage device and a pulse blowback device in the air intake channel. At work, the dust first passes through the self-cleaning air filter in the air cartridge for primary filtration, and then into the original air filter for secondary fine filtration, through the control of the pulser blowback device will be instantly discharged from the gas tank, you can put the first filter cartridge dust blown out so that the dust is filtered and discharged in the first air filter. The secondary air filter element is only used as a security filter element and secondary fine filtration, to achieve cleaner air into the engine to participate in the combustion, more efficiently improve the air filtration precision, ensure a high flow of air through the lower resistance at the same time, reduce engine wear, extend engine life, fuel savings, improve power, save air filter.
