High-precision, porous metal instrument filters.

Today’s sensitive instruments are capable of detecting particles down to parts per trillion (ppt) levels. For the protection of critical instruments, and for processes that demand the highest purity, no filter media protects more reliably than Mott porous metal.
    Unsurpassed in strength and precision, Mott media provides a long-lasting barrier against particles even when placed in harsh environments. And, with fabrication techniques proven for more than 40 years, Mott offers unique filtration features and benefits.

Uniform porosity – A strictly controlled manufacturing process enables Mott to produce uniformly sized and distributed pores, in media grades ranging from 0.2 to 100.

High-efficiency particle capture – Porous metal elements trap particles via “depth filtration,” the effect created by a labyrinth of tortuous, irregular paths leading from one side of the element to the other. This geometry traps particles far more efficiently than media containing straight channels between pores.

No media migration – “Solid-state diffusion bonding” holds filter media together at the molecular level, making it virtually inseparable, even under the harshest conditions. There’s no risk of compromising your solution.

High corrosion resistance – For applications involving corrosive gases or liquids, Mott instrument filters can be constructed of special corrosion-resistant metals and alloys, such as titanium and Hastelloy^®.

High temperature tolerance – All-metal construction, welded joint and seams, and proper material selection endure high temperatures, even in the midst of oxidizing atmospheres.

High pressure tolerance – Unlike “soft” media, Mott sintered porous metal can withstand differential pressures well in excess of 3000 psid because of its rigid sintered structure.

Long life – In most applications, Mott porous metal maintains high filtration efficiency through years of continuous use.

Wide selection of materials – Mott offers the industry’s broadest array of metals and alloys to provide chemical compatibility for virtually any application. Standard construction is generally of 316L stainless steel, but Mott filters can also be made from a variety of metals and alloys, including Hastelloy, Inconel^®, Monel^®, titanium, Alloy 20, nickel and many others.

With hundreds of standard products, there’s a good chance Mott already has the solution for your filtration needs. If not, Mott is more than happy to work with customers to develop solutions to fit the individual application. Working side-by-side with customers, often applying porous metal media where it’s never been applied before, has lead to major advancements. Mott designers and engineers customize solutions to meet new application challenges by integrating current products and components or by developing new ones.
