Products Description
Brief Introduction
A Breathable Filter is a critical protective device installed on the vent ports of containers such as storage tanks, reactors, and fermenters. It enables gas exchange during container breathing while preventing external microorganisms and particulate contaminants from entering. Its core function is to maintain a sterile environment inside the container, prevent product contamination, and balance internal and external pressure.
The device typically consists of hydrophobic filter materials (such as PTFE, PVDF membranes, or glass fiber) and stainless steel/polypropylene housing, effectively filtering particles and microorganisms ≥0.01μm in the air with filtration efficiency up to 99.999%.
