Mott LSI and GSV filters are designed for clean-in-place performance, meaning filter elements can discharge cake build-up without having to open the filter for maintenance. Once a terminal pressure drop has been reached, the cleaning cycle automatically initiates to discharge cake build-up through gas assisted pulse or manually through a backwash cycle.

Particles will embed in the filter media over time, requiring the elements to be cleaned by a third-party company. Various cleaning techniques can be used to prolong life of the elements. For a recommendation of a cleaning company, please contact a Mott representative. It is recommended you keep a spare set of filter elements to continue operations while elements are being cleaned.

FAQs: Porous metal filter elements

Q: What are porous metal filter elements?

A: Porous metal filter elements are advanced filtration devices made from sintered metal that contain thousands of tiny, interconnected pores. These filters are designed to trap and remove particulate matter from gases and liquids, offering high durability, excellent resistance to high temperatures and corrosive environments, and the ability to withstand differential pressures.

Q: How do porous metal filter elements work?

A: Porous metal filter elements work by allowing fluid to pass through the tiny pores while trapping particles on the surface or within the depth of the porous structure. The size of the pores can be precisely controlled during manufacturing, enabling the filtration of particles down to sub-micron levels, depending on the specific application requirements.

Q: What are the advantages of using porous metal filter elements?

A: The advantages of using porous metal filter elements include high mechanical strength, resistance to thermal shock and corrosion, long service life due to durability and the ability to be cleaned and reused, and high filtration efficiency for both gases and liquids. They are particularly beneficial in harsh operating conditions where other filter materials might fail.

Q: Can porous metal filter elements be customized?

A: Yes, porous metal filter elements can be customized in terms of material, pore size, shape, and size to meet specific filtration requirements. Customization allows for optimal performance in various applications, including chemical processing, pharmaceutical manufacturing, food and beverage production, and more.

Q: How are porous metal filter elements maintained?

A: Maintenance of porous metal filter elements typically involves backflushing, ultrasonic cleaning, or chemical cleaning to remove trapped particles. Their ability to be cleaned and reused makes them a cost-effective solution for many industrial processes. Regular maintenance ensures the longevity and efficiency of the filtration system.

Q: Where are porous metal filter elements commonly used?

A: Porous metal filter elements are commonly used in a wide range of industries, including chemical and petrochemical processing, pharmaceuticals, food and beverage, oil and gas, and water treatment. They are ideal for applications requiring high purity filtration, catalyst recovery, gas-liquid separation, and aeration.
