HV filter paper, from a company with a history of three hundred years, provides high-quality solutions for air filter agricultural engine.
The use of HV filter paper in Guohao agricultural machinery filter production ensures that the filter's filtration efficiency meets the ISO5011 testing standard, offering perfect protection for agricultural engine in dusty environments.
Agricultural machinery operates in highly dusty environments with complex particulate compositions, placing extremely high demands on the purification performance of engine air intake systems. Based on test reports of various filter papers, Guohao Filter has conducted extensive screening and selected HV filter paper as the core raw material. Adopting this filter paper, under the ISO 5011 test standard, the filter achieves an excellent initial filtration efficiency of 99.67%, with a dust holding capacity of 1.5 kg per square meter. When the air flow reaches 100% of the rated flow, the pressure drop is only 0.575 kPa. This indicates that the filter can deliver a sufficient air intake volume for the engine consistently from initial use to the later service stage. It enables the engine to operate efficiently with ample power output while reducing fuel consumption.
