Bag filter can effectively remove airborne particles. It has good filtration performance, and is fireproofing. The filter with UL certification can maintain a certain standard of particulate matter filtration during operation, and ensure fire safety in special environments. It is generally used in ventilation systems with high air flow, as the step to the filtration to protect the high-efficiency air filter, and relatively extend the service life of the high-efficiency filter.
