PTFE membrane filter cartridges" are typically components used for filtration, widely applied in industrial exhaust gas treatment, air purification, and liquid filtration fields, to enhance filtration efficiency and ensure the stable operation of the filtration system. The filter elements are sealed in packaging to prevent contamination during use, ensuring product quality.
1.Aseptic air inlet and exhaust filtration for fermenters, storage tanks, batch tanks, etc.
2.Sterile filtration of aseptic packaging gases
3.Sterile filtration of compressed air and nitrogen.
4.Sterile filtration of corrosive gases
* It effectively removes bacteria, viruses, and other microorganisms from the air, providing clean air;
* The resistance to air flow through the filter cylinder is minimal, not significantly affecting air circulation;
* It can operate at higher temperatures, making it suitable for some special application scenarios;
* 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;
