With Pentair Haffmans CPM® Filter Tester, type MK-2, the filter test can be performed in just a few minutes. To simulate microorganisms, a micro-fog or series of smoke-like particles is generated within the filter tester from non-toxic synthetic hydrocarbons. These hydrocarbons form micro-drops of 0.2 to 2.5 μm. This fog is applied under pressure from an integrated compressor to the sterile filter being tested. The fine fog particles quickly penetrate even the smallest leaks in the filter providing immediate visual identification. This procedure does not damage the filter element.
The MK-2 can be used in a central or decentralized laboratory as well as in a dry environment that is sufficiently ventilated.
“The test system is a practical, easy-to use tool that does not require any special knowledge or skills,” Schuster said. “Moreover, you receive a clear result that does not call for further interpretation. After thoroughly testing the device, we added the MK-2 to the list of approved test equipment. The system has fully met our expectations”.
