Compliant with standards:

VDI 3926 Part 1:2004, ASTM D6830-02:2008, JIS Z8909-1:2005, GB/T 6719:2009, ISO 11057:2011

Applicable scope:

This filtration performance tester is mainly used for testing the filtration performance of filter materials (Method 1). The device itself is easy to operate, with a compact and sturdy design. It can quickly and conveniently adjust the concentration value of fine dust in the filtration test, with a high degree of simulation in actual use, simulating various practical situations. The filtered particle size and concentration are measured online through the digital system of a light scattering spectrometer.

Product details:

The dynamic performance testing device for filter materials has the advantages of reasonable structural design, accurate testing parameters, and simple operation. It can complete comprehensive performance tests such as resistance and efficiency during the cleaning, aging, and stability processes of filter materials.

Color LCD operation interface, digital graphics processing, XDT software can independently display the Chinese interface, and can edit and process curves. It has two functions: customization and programmability, and comes with 5 international standard testing methods randomly. Has fault self calibration function. It has encryption function for operation and can be remotely controlled.

Testing process:
