ESPRO’s PV-series PVDF membrane pleated filter cartridges are designed for high-performance filtration in demanding applications. Utilizing a PVDF (polyvinylidene fluoride) membrane as the filter media and supported by a PP (polypropylene) non-woven layer, these filters provide excellent chemical compatibility and ultra-low extractables, making them ideal for applications requiring high purity. The PVDF membrane is specifically designed with low protein adsorption, making it particularly suitable for biological product filtration.

These PV-series cartridges feature a strengthened structure and high porosity, ensuring high flow rates and long service life. The filters offer ultra-low extractable levels, excellent chemical compatibility, and temperature resistance up to 80ºC, making them suitable for use in harsh environments. Additionally, the low protein adsorption and strong mechanical integrity make them ideal for applications that demand reliable performance in sterilization and ultrapure processes. With a retention rate of over 99.99%, these filters deliver efficient and consistent filtration.

Applications for the PV-series filters include semiconductor ultrapure water preparation, food and beverage industry sterilization, corrosive acid or solvent filtration, and biological product filtration, such as virus removal.

With a maximum operating differential pressure of 0.42 MPa forward and 0.21 MPa reverse, these filters are designed to withstand the rigors of high-pressure systems while maintaining structural integrity. The all-PP construction of the support, drainage, end caps, cage, and core further enhances the filter's durability and chemical compatibility, ensuring reliable filtration in a wide range of applications.

ESPRO’s PV-series offers an ideal solution for industries requiring efficient, high-flow filtration with excellent chemical resistance and low protein adsorption in demanding industrial and biological environments.
