Overview
Hospitality Enviro Tech 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
