♦DFFILTRI was founded in 1995, since then we devoted ourselves to research, develop and produce

many kinds of hydraulic filters, air filters, hydraulic system accessories, cleaning and filtration equipments,

pump valve components. DFFILTRI is our brand, which enjoys high popularity and it has successfully 

achieved the position both in China and across the world.

♦DFFILTER filtration technology testing center covers a total area of 450 square meters, of which, 

clean room area of 200 square meters, and cleanliness is up to 100,000 levels. The centre undertakes filtration 

technology inspection and testing for in-house science research, production and industry service.   

♦On-line particle counter of BETAB-HIAC/POYCO type (8000A/8000S) provided by HIAC/POYCO company 

in USA, and its supporting machine"Multi-pass test" and "single-pass test" implements ISO16889 

new standard and other international standards perfectly.  

♦Testing center also has the developed equiment for filter performance testing, which can make the

comprehensive examination for filter element/cartridge performance. These can insure that company’s filter 

with high capacity, long life, high reliable in full compliance with our customer's  requirement.

♦The testing centre can take 7 tests of hydraulic filter performance evaluation, they are as follows:

ISO 2941 Verification of collapse/burst resistance
