mott corporation High Purity Products Positioned for the next challenge in ultra-pure filtration.

Mott Corporation. First and foremost, a supplier of improvement. Before getting into products, let’s talk about possibilities. Seems like a strange way to lead into a product brochure. Especially when there’s so much to say about Mott porous metal filters and flow restrictors. But identifying the goal first, and then either choosing or devising the best possible solution is how our High Purity product family began, and how it continues to grow. What are your biggest needs? Is there a recurring challenge somewhere? While Mott porous metal can’t solve all the problems within a fab, it can do...

Mott Porous Metal. The ultimate media for high-purity filtration. Guaranteed. What makes Mott porous metal media the media of choice. When it comes to strength, precision, efficiency and longevity, no filter media works more reliably than Mott porous metal media. This unique substance makes Mott filters highly efficient and virtually indestructible, offering semiconductor manufacturers a whole new level of comfort, coupled with the tremendous savings of eliminating annual change-outs. For years, users of alternative high-purity filtration media have switched over to Mott filters for the...

The industry’s largest selection of all-metal, high purity gas filters. • In-line point-of-use filters – GasShield point-of-use filters are available in over 20 standard designs, constructed of 316L stainless steel, nickel, or Hastelloy C-22, and rated for flows up to 600 slpm and inlet pressures as high as 5000 psig. • IGS filters – Mott offers a full line of filter and flow restrictor products in designs compatible with the gas system interfaces presently gaining acceptance in process tools, gas cabinets and valve manifold box installations. Our IGS filters are designed to provide greater...

• Bulk and utility filters – Like their point-of-use counterparts, GasShield bulk and utility filters are made to last, offering reliable main-line filtration for years. Designed to accommodate flows from 1000 slpm to 25,000 slpm, GasShield bulk filters are available with 316L stainless steel or nickel filter elements. Additional bulk designs can be provided for applications involving higher pressures or highly corrosive gases. GasShield Particle Capacity Test Filter Tested: Flow Rate: Filter Area: Total particle challenge: 3.6 x 1012 particles/in.2 (7.9 x 1012 particles) Downstream...

A clean process from start to finish. Ensuring the best performance, and maximum out-of-box cleanliness. Every GasShield filter is manufactured, tested and packaged in a Class 100 clean room environment. Fully documented process steps are strictly followed under controlled conditions to keep out contaminants such as hydrocarbons, and reduce post-installation purge and dry-down times for increased productivity. Filters with as little as 10 ppb moisture are available. The most stringent quality control. We’ve always been Mott’s toughest customer. A single Mott filter may be subjected to as...

Microscopic evaluation in the development lab. Designs by request – creating new Mott solutions. For thorough evaluation of new products, and periodic spot-checks of existing ones, Mott maintains a Development and Testing Laboratory. Both scanning electron and optical microscopes, along with computer-controlled porometers, are used to inspect pore size, shape, and distribution. Bench tests can be run with inert and corrosive gases to verify gas/media compatibility, and to ensure corrosion resistance in the field. Particle counters, particlesize analyzers and a fully instrumented test stand...
