Evenly folded filtration paper allows filter efficiency to improve by capturing more dust and extending cleaning interval. As a result it would contribute to lower maintenance cost.
Efficient filter paper and polyurethane rubber seals at both ends proves its high sealing performance, the dust will not enter the engine even in a dusty jobsite, thus longer engine life is secured.
Radial seal element shows high filtration performance and capture more than 99.9% or more of dust in dusty air.
Filter paper and polyurethane rubber are molded into one piece to keep its airtightness.
