SINOTRUK HOWO Air Filter Description
This air filter uses cellulose and polyurethane for high filtration efficiency. Furthermore, the pleated design increases the filtration area. Under normal operating conditions, it effectively traps most dust and impurities in the air, protecting internal engine parts. It remains resistant to deformation even in rainy weather. Internal reinforcing ribs allow it to withstand the vibrations of truck driving without tearing.

SINOTRUK HOWO Air Filter Material Structure Details
The core filter material consists of 80% cellulose and 20% polyurethane. The cellulose is resin-treated wood pulp paper with strong adsorption properties. The addition of polyurethane compensates for the cellulose's strength, improving its shock and tear resistance, resulting in an overall filtration efficiency of 99.99%. The end caps are made of polyurethane and fitted with a highly elastic sealant, ensuring a tight bond with the filter material and preventing unfiltered air from entering. The main body is reinforced with a galvanized stainless steel mesh to support the filter paper, and the galvanization enhances rust resistance.
