Pural NF Filter Test DustBACK

Testing Standards:

ISO 11057, VDI 3926-1, GB/T 6719, ASTM D6830

Applications:

Performance testing is used to filter baghouse filter media, dust aerosols emitted by the generator to simulate actual plant emissions; to ensure experimental reproducibility of the particle size distribution, there are strict requirements, fully meet the standards of ISO 11057, VDI 3926- 1, GB/T 6719, ASTM D6830.
