Particle Filtration Efficiency Test_ Experimental Video of Vaultcreation
Comparative test : Vault’s PET filter, KF80/94 mask filter, MeltBlown filter, Nonwoven fabric filter
[Material]– Vault’s PET filter, KF80/94 mask filter, MeltBlown filter, Nonwoven fabric filter
[Experimental method]– Installing the test filter in the middle of a cylinder measuring 900mm in width, 70mm in outside diameter(inside diameter 66mm)
– Conduct the experiment by attaching part of rubber gloves to the entrance of the cylinder so that dust can be concentrated into the cylinder
– Prepare 5 cups fo 5 to 10μm dust(1.2g for each test)
– Apply 1.2g dust to each test cylinder
– Spray the blower into each cylinder for 5 seconds(27m/s wind velocity)
– Dust passed through the test filter and smeared in the kitchen towel at the other end
[Result]
– Ranking of blocking efficiency
(1) Vaultcreation PET filter/ KF94mask filter
(2) KF80mask filter
(3) Melt Blown filter
(4) Nonwoven fabric filter
