Primary bag filter

The primary bag filter is used for the first filtration of fresh air in the purification air conditioning system. It mainly filters suspended particles larger than 2μm and various foreign substances in the atmosphere (such as cleaning dust, pollen, mites, sand, spray paint, fiber dust, willow catkins, etc.).

Product feature

The metal outer frame and the metal inner frame provide support. The structure is sturdy and easy to install and disassemble. The filter bags and the inner frame are fixed by perforated riveting or metal strip crimping process

● High-quality fluffy fiber filter cotton

High-quality polyester fiber filter material, made by stepwise encryption technology, has excellent filtration performance. The filter bags are made by five-thread sewing or microwave hot melt edge sealing process. The filter bag and the supporting frame adopt a rigid connection structure to ensure the sealing performance of the filter bag and the reliability of operation, and prevent secondary dust generation

●High dust holding capacity, low resistance

The filter bags adopt a standard V-shaped structure that conforms to the airflow, featuring strong airflow stability, ensuring the effective utilization of the filter medium and guaranteeing the filtration effect. It can be cleaned and reused, and has a long service life
