Primary effect bag filter
The primary effect bag filter is an air pre-filtration product with high dust holding capacity. It adopts a multi-bag structure design, which can provide a larger filtration area in a limited installation space and effectively intercept dust, fibers, hair and other large particle pollutants in the air.

Compared with plate filters, bag structures have higher dust holding capacity and longer service life, which can significantly reduce filter replacement frequency and system maintenance costs. Products are widely used in the pre-filtration stage of air conditioning units, fresh air systems, industrial ventilation systems and clean room air treatment systems.

Why choose primary effect bag filter

Larger filtration area

The multi-bag structure provides an effective filtration area much higher than that of plate filters, improving filtration efficiency and reducing operating resistance.

High dust capacity design

Can hold more dust particles, extend the replacement cycle and reduce maintenance costs.

Reduce system operating costs

Low resistance operation helps reduce fan energy consumption and improve the overall system efficiency.

Prolong the life of the back-end filter

Effectively intercept large particle pollutants and protect medium-efficiency and high-efficiency filters.

Stable and reliable operation

Using high-quality filter material and solid bag structure to ensure long-term stable operation.

Support customized production

The size, number of bags and filtration level can be customized according to project requirements.



Main features

  • High dust holding capacity

  • Low operating resistance

  • Long service life

  • Large air volume handling capacity

  • Multi-bag structural design
