Product catalog summary
Overview of Mott Porous Metal Products
Mott Corporation specializes in high-strength, high-performance porous metal media used in filtration, flow control, sparging, and dispersion. These products are recognized for their reliability and durability in capturing particles, controlling flow, and facilitating gas/liquid interactions.
Key Features
  • Long Life: Maintains efficiency and structural integrity over extended use.
  • High Strength: Suitable for high differential pressures and flow rates.
  • Uniform Porosity: Controlled sintering ensures consistent pore size distribution.
  • Cleanability: Restorable to original efficiency through cleaning methods like backpulse.
  • No Media Migration: Solid-state diffusion bonding prevents separation under harsh conditions.
  • Heat Tolerance: All-metal construction withstands high temperatures.
  • Material Options: Available in various metals and alloys for specific needs.
Manufacturing Process
The process involves pregrading metal powders, compressing them into shapes, and sintering in controlled atmospheres, ensuring precise control over density, permeability, and pore size.
Research and Development
Mott's R&D laboratory supports product development and testing with capabilities like metallographic analysis and particle size analysis.
Design Considerations
  • Application Considerations: Factors like particle retention, temperature, pressure, and corrosive effects are crucial.
  • Media Considerations: Pore size and density can be adjusted for performance.
  • Manufacturing Considerations: Guidelines for forming, machining, brazing, and welding to maintain permeability.
  • Cleaning Methods: Various techniques recommended based on application needs.
Applications
Used in air bearings, instrument filters, breathers, flow restrictors, flame arrestors, silencers, wicks, spargers, polymer filters, and fluidizers.
Standard Shapes and Sizes
Offers standard shapes like seamless tubes, bushings, cups, sheets, and discs, with custom sizes available.
Flow Characteristics
Flow curves show the relationship between pressure drop and flow rate for different media grades and thicknesses.
Flow Characteristics and Testing
Flow characteristics for 316L SS porous media are provided for both liquid and gas, with specific formulas for pressure drop calculations. Tests were conducted at 70°F with water.
Particle Size and Collection Efficiency
Details initial collection efficiency for particle sizes from 0.2 to 20 µm, tested per IBR E304 and ASTM F795 standards.
Material Specifications and Permeability
Specifications for 316L SS rolled sheets and seamless tubes include bubble point, tensile strength, yield strength, and permeability coefficients.
Applications of Mott Precision Porous Metal Products
Used in industries like chemical/petrochemical, food/beverage, medical/pharmaceutical, electronics, instrumentation, textile, refinery, and energy.
HyPulse Filters and Systems
Offers HyPulse filters for liquid/solids and gas/solids separation, providing high-efficiency filtration solutions.

All porous products, whatever the material of construction,have specific properties which must be taken into account in design and manufacturing processes.Proper attention to these characteristics will help control costs in manu-facturing, while at the same time, produce the best combination of properties and performance.In order to select the best media for any application,one should be able to provide Mott with the following information: Brazing Brazing porous metal is extremely difficult. The porous metal tends to act as a wick, so when molten braze is applied, it is soaked up into the pores,...
