Introduction
Mott Corporation offers high-strength, all-metal Utility Line and Bulk Filters as a reliable alternative to traditional fluoropolymer filters. These filters are designed for utility lines inside wafer fabs and gas pad flow streams, providing resistance to high temperatures and pressure spikes.

Specifications
The filters are constructed with patented sintered nickel porous media, ensuring durability against pressure and flow fluctuations. They are suitable for high temperatures, up to 450°C (842°F), and provide 9-log filtration of particles down to 0.003µm. The filters are rated for maximum inlet pressures between 300-650 psi and are helium leak-rated at a maximum of 1 x 10-9 atm cc/sec.

Performance
Mott filters offer superior flow versus differential pressure performance compared to competitive Teflon® products. They achieve greater than 99.9999999% particle removal efficiency, confirmed at the most penetrating particle size of 0.08µm.

Construction and Design
The filters feature all-metal construction with a 10 Ra surface finish on internal wetted components. The all-welded design eliminates out-gassing from polymer seats and structures. Standard fittings include compression, VCR, and tube connections, with other types available upon request.

Packaging and Standards
Filters are assembled, welded, and tested in a Class 100 environment, meeting SEMI Standards. They are double-bagged in a Class 100 clean room, with the internal bag made of Nylon 6 and the outer bag of poly.

Warranty
Mott provides a 15-year warranty for GasShield® bulk gas filters and a 5-year warranty for utility line filters, covering specified retention and media integrity standards. The warranty is contingent upon proper installation and use according to Mott's published specifications.

Conclusion
Mott's Utility Line and Bulk Filters offer a robust solution for high-temperature and high-pressure applications, ensuring long-term reliability and efficiency in filtration processes.
