Product Q&A

Q:What standard do medium efficiency filter bags follow?

They mainly comply with EN 779, the latest global filter standard ISO 16890, and China national standard GB/T 14295. Common grades include M5, M6, F7, F8, F9; these correspond to ePM10, ePM2.5 levels under ISO 16890.

Q:What are the initial resistance and recommended final resistance for replacement?

Initial resistance ranges 80 to130 Pa depending on filter grade,The suggested final resistance for replacement is 250 to 300 Pa,Air flow will drop sharply once exceeding this value,

Q:How long is the normal service life?

With G3/G4 coarse filter installed upstream: 3to6 months for office, mall and general clean environments; 1to3 months for heavy-dust industrial workshops. Service life mainly depends on the working condition of the front coarse filter.
