Description
Ensuring purity at the final stage of filtration
PFs+ filters help ensure clean, high‑quality compressed air and nitrogen in the final stage of your process. Their design supports stable performance in demanding food, beverage and pharmaceutical environments where air purity is critical.
Made for purity‑critical processes
PFs+ filters help ensure the clean, dependable air and gas your process requires at its most sensitive stage, supporting sterile‑grade applications and maintaining consistent product integrity.
Produced to meet demanding quality expectations
Our PFs+ filters are manufactured in controlled, ISO‑certified environments using compliant materials and full batch traceability, giving you confidence in both performance and regulatory alignment.
Benefits
Technical benefits
Hydrophobic media for effective moisture barrier
The PFs+ uses hydrophobic filter media that naturally repels moisture, helping maintain consistent airflow and filtration performance even in humid or demanding operating conditions.
Standard quality
With proven bacteria‑retention capability and HEPA‑level filtration, the PFs+ delivers the level of purity required for final filtration in hygiene‑critical applications.
Sterile grade filtration
PFs+ filters meet sterile‑grade requirements by retaining more than 10⁷ microorganisms per cm² of filter surface, achieving an efficiency greater than LRV 7 during validated bacterial challenge testing. This level of performance ensures the PFs+ provides the contamination control needed for final filtration in highly sensitive applications
Smooth airflow with low pressure drop
The filter is engineered to allow high flow at low resistance, supporting efficient system operation and helping reduce overall energy demand.
Clean, compliant construction
Made without silicone, BPA, surfactants or fiber‑shedding materials, the PFs+ is produced in ISO‑certified clean environments using materials that comply with FDA Title 21 and EU Regulation 1935/2004. Each filter includes full batch traceability, giving you transparent proof of quality and safety for hygiene‑critical applications.
