The filter material dynamic filtration performance tester is mainly used to test the filtration performance of filter materials. The equipment itself is easy to operate, compact, and sturdy in design. The dust concentration value of the filtration test can be adjusted quickly and conveniently, and the actual use simulation degree is high, simulating a variety of actual conditions. Afterward, the particle size and concentration are measured online by the digital system of the light scattering spectrometer.

As a modern technology enterprise integrating R&D, manufacturing, sales, training, and service, Standard Group (Hong Kong) Co., Ltd. is committed to delivering more testing instruments to the market, providing testing instruments for textiles, leather, combustion, automotive interior and exterior trims, material environmental climate aging, etc., and non-standard customization is also acceptable. Targeted tests can be carried out according to customer requirements before purchase to ensure that the purchased instruments are suitable.

Comply with the standards:

GB/T6719-2009 Technical requirements for bag dust collectors
