50mm In-Line Sterile Vent Filter with PTFE - China Suppliers & Factory for Air and Gas Filtration
Product Introduction
To serve the increasing demand for sterile applications and pure fluids in modern medical and biopharmaceutical fields, we provide a 0.22 μm PTFE vent filter of 50 mm diameter, which is ideal for sterile venting applications, low-volume non-aqueous fluid sterilization, in-line sterilization of air and gases, and particle removal.
This in-line sterile vent filter utilizes high-end polytetrafluoroethylene (PTFE) as its primary venting material, boasting excellent chemical stability and corrosion resistance and without fiber shedding issues. Its 0.22-micron pore size demonstrates outstanding performance by blocking microorganisms, bacteria and large particles in the air, and ensures a sterile environment inside, thereby guaranteeing the sterility of fluids and providing clean, sterile and safe environment for critical processes. Meanwhile, the filter media has large surface of 50 mm diameter which provides greater throughput and high air flow rate, and that means excellent filtration efficiency and processing capacity. Through well-performed filtration media and optimized design, this air vent filter is easy to integrate into various fluid handling systems, offering users a flexible and efficient solution.

Frequently Asked Questions
Q:What is the primary membrane material of the 50 mm vent filter?
The filter utilizes hydrophobic polytetrafluoroethylene (PTFE) reinforced with polypropylene as its primary filtration media, offering superb chemical stability and preventing fiber shedding.
Q:What is the pore size and how does it ensure sterility?
It features a 0.22-micron (μm) pore size, which is highly efficient at blocking microorganisms, bacteria, and large airborne particles to maintain a sterile internal environment.
Q:How can this PTFE vent filter be sterilized?
The filter can be sterilized using an autoclave at 121°C for 30 minutes, or via Ethylene Oxide (ETO) sterilization, supporting up to 60 sterilization cycles.
Q:What type of connectors does the filter housing have?
It is designed with a stepped hose barb connector that accommodates tubing sizes from 6 mm (1/4 inch) to 12 mm (1/2 inch) for easy and secure handling.
Q:What is the maximum operating limit for pressure?
The filter housing has a maximum operating pressure rating of 3.0 bar at a temperature of 20°C.
