undefined 拷贝11Enkonduko:

It is made of anti-fracture PET organic synthetic fiber, featuring a high dust holding capacity and low resistance. This means it can effectively capture dust particles in the air over a long period without excessively hindering air circulation, thereby ensuring the normal operation of the ventilation system.


Application:

Ventilation System Pre-filtration:

Widely used in pre-filtration of various ventilation systems like central air conditioning and fresh air systems in commercial buildings, industrial plants, hospitals, and schools. It filters out large dust, hair, fibers, protects medium and high-efficiency filters, and extends the filtration system's life.


Clean Room Fresh Air Filtration:

In clean rooms' fresh air systems, it's the pre-filtration outlet, filtering introduced outside air, removing coarse particles, and providing clean air.


Adverse Environment Ventilation Pre-filtration:

Suitable for outdoor adverse environments like garbage sites, sewage plants, and waste gas outlets. It filters dust, pollutants, and odors to improve air quality.
