HT TefloGas Filter Cartridges

Hydrophobic PTFE Membrane · Sterile-Grade Filter for Critical Gas Filtration

HT TefloGas Filter Cartridges are composed of a PTFE membrane with advanced high-temperature-resistant core and internal adaptor. They are specially designed for air, gas, and vent sterile filtration at critically high temperatures.

Features and Benefits of HT TefloGas Filter Cartridges

Designed for Water Intrusion Test (requires no alcohol)
Oxidation-resistant materials provides longer service life in high temperature air and vent applications
Exceptionally high flow rates with low pressure drops
Part/Serial numbers are laser-etched and have 2D matrix code for easy tracking
Filter construction provides steam resistance at high temperatures

Quality Standards

Integrity Test correlates to ASTM F838-05 Bacterial Challenge Test (BCT)
Each filter is individually Integrity Tested prior to leaving the factory
Each filter is Fully Traceable with a unique serial number
Designed, developed and manufactured in compliance with ISO9001
Full Regulatory Compliance with the following:
- 21CFR.210.3(b)(5)(6), 211.72 for Non-Fiber Release
- Endotoxins: <0.25EU/ml/10inch filter
- USP <88> Plastic Class VI-121°C
- FDA 21 CFR177-182 & EU 1935/2004/EC
