Performance of filter media is essentially defined by parameters such as differential pressure, gravimetric filtration efficiency and dust holding capacity. The Topas Manual Filter Media Test Rig MBP 116 can be applied to determine these filter parameters at flat sheet materials. This test rig has been designed as universal testing equipment. It combines a simple and robust setup with a manual and therefore cost efficient handling and operation. Because of its vertical test channel setup it is especially suitable for the testing of filter media according to ISO 5011.
