The test bench uses a polydisperse experimental aerosol (DEHS or
NaCl) to quantify the dust. Under the action of a clean air flow
(negative pressure), the conventional performance test is carried
out through the sampling of aerosol particles and the pressure
difference measurement point of the filter media under test .
The test bench refers to the advanced design concepts of similar
international equipment (such as the 8130 model of the US TSI
company), but it is also suitable for the test status of related
domestic industries. The independently developed program software
runs stably and reliably and is easy to operate. Simple operation
interface, the operation parameters are clear at a glance.
Different dust sources (DEHS and NaCl) can be switched freely. It
is suitable for testing a variety of air filter materials
(meltblown, glass fiber, PP, film and other filter materials),
medical masks and some labor protection products.
