Product description
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 the aerosol particles and the pressure difference measurement point of the filter media under test .
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, suitable for testing a variety of air filter materials (meltblown, glass fiber, PP, film and other filter materials) and labor protection products.
Application:
It is used for non-woven filter materials, glass fiber filter materials, new filter materials, filter efficiency, resistance test, and mask tightness test. The test data of the product has been compared and tested by large-scale test equipment of well-known brands at home and abroad, and has high consistency. The product is highly recognized by the experts of the Cleanliness Association and the filter material industry manufacturers.
