PFA Nitrogen Gun (1/4 or 3/8 inch) – SG-1 Series

The PFA Nitrogen Gun is suitable for use in ultra-high purity (UHP) semiconductor applications. It utilizes a molded PFA body with precision-machined sealing areas. These materials, coupled with PFA interior surfaces and a one-piece machined modified PTFE diaphragm and poppet, afford the SG-1 Series nitrogen gun with high leak integrity and exceptional corrosion resistance for performance in applications where cleanliness is critical.

The SG-1 Series features a wiper seat, which creates a reliable diaphragm to body seal and provides positive through flow shut-off. Its unique design eliminates the need for elastomer seals, while providing excellent flexibility and long life. It is available with 1/4 inch FNPT or 3/8 inch Parflare connections. The connections reduce assembly and installation time, while ensuring minimal particle generation for contamination-free operation.

Additional options include a 0.2 or 0.5 micron filter and a coiled hose assembly.
