Microline realizes test and measurement solutions. The pressure drop test for air filters is used to test the performance of dry type inlet air cleaning equipment for internal combustion engines and compressors, generally used on automotive or industrial applications, following ISO 5011:2020 rules. “The test shall be performed on complete air cleaner assembly or on single air cleaner elements – the company explains –. Air flow restriction or differential pressure test are performed to evaluate the pressure loss across the unit under test which will result when air is passed through under predetermined environmental and process conditions. Other tests are on request, as required from the cited rules”. The equipment is installed inside a climatic cell able to reach and maintain the testing environmental conditions required. One turbine flow generator is used to provide the needed air flow, installed inside one soundproof chamber placed outside the climatic cell. Compliance with the measurement accuracy imposed by the norms is achieved with the aid of state-of-the-art and high-precision instrumentation. The interface software is used to define, view and monitor the test phases. “The numerical and graphic presentation of the results obtained – the company comments – is a valid help to define the improvements to be made for the development of the product and to monitor its characteristics over time”.
