Abstract: To widen the application scope of pulse-jet cartridge filter, a test was made on its performance in a low-dust environment. The result shows that the pulse-jet cartridge filter has very good dedusting and purification effects on low concentration dust （The purification efficiency is up to 99.99%), illustrating its application feasibility and reliability in low dust environment.  

Key words: Pulse-jet cartridge filter, Performance test, Low dust environment, Purification efficiency
