Emflon® PFR Sterilizing Membrane Filters – The Optimal Air & Gas Filtration Solution for the Food & Beverage Industry | NTN

Introduction

In food, beverage, pharmaceutical, and industrial manufacturing processes, compressed air and process gases frequently come into direct contact with products or product-contact equipment surfaces. Without proper filtration, this air and gas can become a hidden source of microbial and particulate contamination, seriously affecting product quality and consumer safety. Emflon® PFR membrane filters from Pall Corporation are a range of validated PTFE sterilizing-grade filters purpose-built to solve this exact challenge, giving your production process maximum protection.

About NTN

NTN Technology Trading Co., Ltd. was established in 2014 by a team with many years of experience in industrial engineering and factory automation. NTN specializes in importing and distributing industrial equipment directly to end-users across several key categories: pneumatic equipment, sensors, industrial electrical equipment, motors and controllers, automation, power transmission components, and measuring instruments.

Within its pneumatic equipment portfolio — alongside cylinders, pneumatic valves, and vacuum equipment — NTN also supplies air-treatment products such as air filters, regulators, and FRL oil separators. This makes the Emflon® PFR sterilizing membrane filter a natural and fitting addition to NTN’s air and gas treatment product line, especially for food and beverage manufacturers that require strict hygiene and safety standards.

What Is Emflon® PFR?

Emflon® PFR is a family of filter cartridges using 100% PTFE membrane, designed for the sterilizing filtration of air and gas. It effectively blocks microorganisms and particulate contaminants from entering products or process systems. These filters are widely used in compressed air systems and tank venting applications across food, beverage, and chemical manufacturing plants.

Key Advantages of Emflon® PFR Membrane Filters

1. 100% Hydrophobic PTFE Membrane with a Fixed Double-Layer Structure

Emflon® PFR uses a double-layer membrane with a fixed pore structure, eliminating the risk of media flexing or contaminant unloading — a common limitation of traditional depth filters.

2. Tested and Validated for Microbial Retention

Microbial validation is the most sensitive validation method for sterile air cartridge filters; expected microbial removal performance should never be based on pore-size rating alone. Emflon® PFR meets the liquid bacterial challenge validation requirement of ≥10⁷ cfu/cm² effective filtration area under ASTM Method 838-05, delivering sterile effluent in line with FDA Guidelines (2004).

3. High Hydrophobicity

PTFE filters used for air filtration must be highly hydrophobic to effectively remove microorganisms in both liquid and aerosol bacterial challenge conditions.

4. Outstanding Robustness Across Repeated Sterilization Cycles

Because these filters undergo repeated in-situ steam sterilization with heating and cooling cycles during operation, an extremely robust design is essential. Emflon® PFR is validated for repeated steam cycling, providing excellent resistance to mechanical damage.

5. 100% Integrity Tested Prior to Dispatch

Every Emflon® filter is 100% tested before release. These in-situ integrity tests are correlated with liquid bacterial challenge testing, confirming the filter’s retention and removal efficiency even under the most stringent liquid suspension conditions.

6. Food-Contact Compliant

Emflon® PFR filters meet national and international standards for food-contact compliance.

7. Validated for 0.2 Micron Bacteria Removal

Validated for 0.2 micron bacteria removal in both liquid and aerosol challenge tests, Emflon® PFR helps improve fermentation yields and provides reliable protection against contamination.
