Abstract: An axial flow filter contains: a filtration unit. The filtration unit includes at least one filtering material and plural connection materials. Each filtering material spirally rolls outward from its inner end, and said each filtering material has a small-diameter portion formed on the inner end thereof and has a large-diameter portion arranged on an outer end thereof. Between the small-diameter portion and the large-diameter portion defines a height difference, said each filtering material rolls outward to define a gap between any two adjacent filter layers, and a first connection material is fixed between said any two adjacent filter layers and is coated along a middle section of said each filtering material as said each filtering material rolls outward, such that said any two adjacent filter layers of the at least one filtering material are spaced at a fixed distance so as to stop the gap.

Abstract: An interface air filter and assembly for use with an internal combustion engine is disclosed. The assembly has a housing having an air intake port and an opening. There is an air filter assembly comprising an air filter having a closed end and an open end and a reducing coupling. The reducing coupling has a first end with a first engaging member having an external circumference and outer surface, a second end with a second engaging member having an external circumference less than the first engaging member external circumference, and the second engaging member has an inner surface. The first end of the reducing coupling is attached to the open end of the air filter. The air filter assembly is in contact with the housing such that the air filter resides within the housing and the outer surface of the first engaging member engages the housing. The inner surface of the second engaging member is adapted to contact an air intake tube outer surface so that air can pass from the air intake port into the housing then through the air filter and into the air intake tube.
