Wafergard® III NF-750 In-Line Gas Filters

Wafergard® III NF-750 In-Line Gas Filters

Superior particulate filtration for high-purity gas system filtration


● Cleanest, most efficient all-metal filters available
● Patented nickel filter membrane offers superior corrosion resistance and excellent compatibility with inert and reactive gases. (Not recommended for use with CO, O3 and low-level hydride dopant gases.)
● Ideal for high-temperature and dynamic-pressure applications
● Typically used for flows up to 750 SLPM
