Portable Melt-Blown Fabric Test Equipment for Filter Efficiency and Resistance
Application This test equipment is used to quickly test filter efficiency and resistance of some protective materials including melt-blown fabric and plane mask at 32L/min flow rate, which is specially suitable for test comparison among various filter medias from different suppliers. It can be also used as a tester of resistance and uniformity for manufacturer producing semi-finished products of melt-blown.

Key features 1. Particles in ambient air will be used as the detection medium. Calibration filter paper is provided, and filter efficiency for 0.3μm NaCl particles under standard conditions will be tested by adjusting the balance coefficient. 2. Used for relative comparison, not absolute judgment. As a non-standard test equipment, environmental factor may affect the final test results. Therefore, it is specially suitable for the relative comparison among melt-blown materials from different brands, that will become important info for reference. 3. Meanwhile, in order to achieve the accuracy of the absolute value of the test result as much as possible, the instrument is designed with balanced correction, that will be helpful to make absolute value of the test result closer to the value from standard instrument. 4. Environment has zero effect on the resistance (Pa), so the test result can be compared with the value from standard instrument.
