Our Laboratory

GURFILTER prides itself on its fully equipped laboratory that allows us to perform inspection and quality comparison tests for filters and filter elements, as well as filtration media performance tests.
Having the advantage of performing in-house comparison tests for all types of filters/elements for liquids (such as oil and fuel filters) allows us to monitor and maintain a high quality of automotive filters, giving our customers the certainty of a reliable supplier.2
Within GURFILTER's laboratory, filtration media tests are being performed to ensure that the media used for our filters is of best quality and uniformity. All tests are made according to international standards, using high quality new equipment. The laboratory is managed and operated by a skillful and experienced team of engineers that were trained and accredited in international courses. All pieces of equipment are calibrated and controlled by a registered institute
GURFILTER's laboratory can supply comparison test reports for filters, under the umbrella of ISO standard procedures. These tests are made with reference to OEM filters/elements as they are performed in the original filter housing or a universal housing
