Multi-pass Test Stand

Multi-pass Test Stand is based on ISO 19438, ISO 4548-12 and ISO 16889 testing standards, mainly used to detect hydraulic filter performance. The on-line particle counting method is used to evaluate the liquid filtration performance, the actual filtering accuracy and the amount of pollutants per unit area of ​​tested filter media. Meanwhile, multi-pass test stand can also provide valuable data for designing filter, the correlation between flow and pressure drop per unit area of filter media, the small flow of the hydraulic filter performance and pressure drop flow characteristics of test.
