Test equipment of specific capacity retention of contaminant and gravimetric efficiency in sample flat on the filter media

摘要

Test equipment of specific capacity retention of contaminant and gravimetric sample efficiency in flat filter medium.It deals more particularly with a new equipment 1 mainly developed to perform tests on samples for flat filter medium MF, used in the manufacture of air filters specially manufactured for automotive equipment, this provided with a simplified structure, requiring a Being coupled to an air succionador equipment for its operation.Presenting a substantial reduction of costs for the industrial feasibility, and to do so, consisting of a body (2) is split (a) and (b) with a higher entry (3) format, preferably tubular, for the flow of air and dust test, in addition to a grid (4) focuses L developed to support the sample (MF) to be tested, and finally.A lower outlet (6) and a tubular air outlet is connected to a piece of equipment called flow box (FB), i.e., a sucker which simulates the aspiration of the internal combustion engine, generating a flow of air is controlled to measure the dust test
