GAOTek Filter Material Performance Tester

Description

Overview

GAOTek filter material performance tester is used to quickly test filter efficiency and resistance of some protective materials including melt-blown nonwoven fabric and plane mask at 32 L or min flow rate, which is especially suitable for test comparison among various filter medias from different suppliers. It can be also used as a tester of resistance and uniformity for manufacturers producing semi-finished products of melt.

Features

• Particles in ambient air will be used as the detection medium
• Calibration filter paper is provided
• Filter efficiency for 0.3 μm NaCl particles under standard conditions
• Will be tested by adjusting the balance coefficient.
• Used for relative comparison, not absolute judgment
• Environmental factor may affect the final test results
• Therefore, it is especially suitable for the relative comparison
• Among melt-blown materials from different brands
• Will become important info for reference.
• Achieve the accuracy of the absolute value of the test result
• The instrument is designed with balanced correction
• Will be helpful to make absolute value of the test result
• Environment has zero effect on the resistance (Pa)
• The test result can be compared with the value from standard instrument
