Glass fiber Pleated Filter Cartridge for Pharmaceutical Air
Prefiltration 1.5μm/20"
General Description of Pharmaceutical Air Prefiltration:
A glass fiber pleated filter cartridge used for pharmaceutical air
pre-filtration is a highly efficient filtering component
specifically designed for pharmaceutical industry air purification
systems. The application of these filter cartridges in the
pharmaceutical industry is critical, as they provide high-quality
air filtration, which helps to ensure a sterile production
environment. This, in turn, guarantees the quality and safety of
the pharmaceutical production.
Application of Pharmaceutical Air Prefiltration:
1.Pharmaceutical industry: serum and blood product filtration, cell
culture media pre-filtration, vaccine purification filtration, air
prefiltration.
2.Food industry: wine clarification filtration, draft beer
pre-filtration, air prefiltration.
Features and Benefits of Pharmaceutical Air Prefiltration:
* With high efficiency filtration capabilities, it effectively
removes particles, bacteria, viruses, and other contaminants from
the air, ensuring that the air entering the pharmaceutical
production area meets stringent sterilization standards;
* Utilizing a pleated design, it provides a larger filtration area,
thereby achieving higher filtration efficiency within a limited
space;
* The design takes into account the uniformity of airflow
distribution, ensuring that air flows evenly across the entire
filter surface, avoiding localized high pressure losses, thus
enhancing filtration efficiency and system operational efficiency;
* Strict quality control system, complete production process flow;
* Short delivery period;
* Flexible payment method: T/T, L/C, West Union, Paypal;
* Free technical support;
* Other specific sizes can be customized;
