Pleated Filter Cartridge

Purification equipment generally refers to the products which can remove the particles which is 0.3um or above 0.1um to improve the local cleanliness. Its key point is to maintain local high cleanliness, and the specification or size is also determined by the required scope of protection. Personalized design can be carried out according to the actual needs of customers, such as system control, parameter monitoring, operation mode and so on. According to different purpose of use, purification equipment can be divided into several types such as laminar air flow unit, dispensing booth, dynamic pass box, clean bench, FFU, VHP decontamination chamber and so on. No matter what kind of product, the most basic form is a fan with a high efficiency filter. According to the need at site, some products also can be designed as vertical airflow or horizontal airflow.

Air Filter

Air filter are mainly apply for clean air-conditional system or delivery wind for purification equipment. According to the filter class level, it divided into primary filter(G1-G4), Fine Filter(M5~M6, F7~F9), HEPA filter(E10~E12, H13~H14), ULPA filter(U15~U17). According to the structure, there are Panel filter, Bag filter, V-bank filter(Box type), Separator filter, Compact HEPA filter, Gel sealed HEPA filter etc. Primary filter could filtering 5um bigger particles, medium filter could filtering 1um bigger particles. They prevent the particles deposit at the surface measuring element surfaces such as temperature and humidity sensor, heat exchange element surface or air hose and improve the system controllability. At the same time they protect the endmost HEPA filter and extend the lifetime. HEPA filter mainly used at the endmost purification. The gas entering into the clean room or clean space directly after filtering to keep the environment reach the usage demand.
