Mott manufacturing.
Ensuring the best performance, and maximum out-of-the-box cleanliness.

Mott's state-of-the-art TIG welders, operated in a Class 100 clean room, join filter housings and elements with the utmost precision.

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 many as 30 quality-control measures. And to meet today's standards, computer-based documentation and scheduling are inte- grated with Mott's manufacturing database to ensure process consistency and timely production. Prior to shipment, GasShield filters are 100% pressure-burst tested and helium leak rate tested. Each filter is then pulsed with clean dry nitrogen

and tested with a CNC (Condensation Nucleus Counter) particle counter for zero downstream counts. For even greater assurance, independent testing laboratories evaluate the performance of GasShield filters, and submit their findings in detailed reports. Suffice it to say that by the time any GasShield filter arrives at your location, it will have proven its integrity several times over.

Microscopic evaluation in the development lab.
For thorough evaluation of new products, and periodic spot-checks of existing ones, Mott maintains a Develop-ment 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, particle-size analyzers and a fully instrumented test stand are used to evaluate filter performance.

A significant investment in R&D, year after year.
Mott continuously supports Research and Development efforts to provide solutions based on best-available industry technologies. And because these technologies change frequently, we work hard to stay abreast of – and even drive – advancements. There is simply no other way to maintain our commitment to meeting customer requirements with the best means the industry has to offer.

Designs by request – creating new Mott solutions.
With dozens of GasShield configurations, there's a very good chance Mott already has the solution you need. Yet it's also possible that yours is an altogether new kind of challenge. If that's the case, we're more than happy to work with you. Developing new products has been the cornerstone of Mott's growth and success. Working side-by-side with customers, often applying porous metal where it's never been applied before, has led to major advancements in controlling costs and increasing manufacturing efficiency. Mott has, for example, worked with specific customer requirements to create load lock chamber diffusers for their individual tools. So, if you don't see what you need here, or in one of our catalogs, ask us. If anyone can customize a porous metal solution to the task at hand, it's Mott.
