FAQs: Bulk Gas Filters & Filtration
Q: What is a bulk filter in the context of ultra-high purity applications?
A: A bulk filter is a specialized filtration device designed to handle large volumes of gas, ensuring the removal of contaminants and impurities, especially in ultra-high purity applications like semiconductor manufacturing.
Q: How does Mott’s bulk filter ensure 9-log filtration?
A: Mott’s bulk filters are engineered with advanced porous metal technology, allowing them to achieve 9-log filtration. Mott filters are manufactured to the highest quality and the highest precision porosity in the market. This ensures that the gas passing through is of the highest purity, free from particles and contaminants.
Q: Are Mott’s bulk gas filters compatible with various semiconductor process gases?
A: Yes, Mott’s bulk gas filters are designed to be compatible with all high purity semiconductor process gases, ensuring versatility and reliability in a range of challenging applications. Mott filters are used in the most challenging semiconductor chip manufacturing process, including advanced node technologies < 7nm.
Q: How do Mott’s bulk gas filters contribute to faster “dry down” times?
A: Mott’s bulk gas filters are crafted with materials and designs that allow for quick “dry down,” meaning they achieve optimal performance in minutes rather than hours, reducing downtime and increasing efficiency.
Q: Can Mott’s bulk gas filters handle corrosive gases?
A: Absolutely. Mott’s bulk filters are available in various materials, including Stainless Steel, Hastelloy®, and Penta® Nickel, making them suitable for handling a range of gases, including corrosive ones.
