What is a metallic filter?

A metallic filter is a type of filter system typically made from metallic materials such as stainless steel, Titanium, or Hastelloy C276/C22, amongst others. These filtration systems are designed to remove impurities, particulates, or unwanted substances from fluids or gases passing through them.

Metal filters represent a new class of filters characterized by low densities and innovative physical, mechanical, thermal, electrical, and acoustic properties. Metal filter elements offer a unique combination of attributes that distinguish them from traditional materials and make them highly versatile for various applications.

These filters come in different shapes, sizes, and configurations depending on the specific business requirements. They may feature different pore sizes or mesh densities to achieve varying levels of filtration efficiency. Overall, metallic filters are valued for their reliability, longevity, and effectiveness in removing contaminants from fluids and gases.

What materials are used in metal filters?

Metal filters are primarily composed of stainless steel, titanium, hastelloy, and other similar materials, which are widely recognized for their effectiveness and versatility in various filtration applications.

Powder Sintered

Stainless steel

Stainless steel is a popular choice for metal filters due to its corrosion resistance, durability, and ability to withstand high temperatures. It is suitable for a wide range of applications, including air and water filtration systems, automotive engines, and industrial processes.

Powder Sintered

Titanium

Titanium filters are lightweight, strong, and corrosion-resistant, making them suitable for applications in aerospace, medical devices, and marine environments where strength-to-weight ratio is critical. The chloride ion resistance is also an important feature of titanium sintered filters.

Multilayered Sintered

Hastelloy C276/22

Hastelloy C276 or C22 are used as filter media due to their exceptional corrosion resistance. These alloys are particularly well-suited for applications where exposure to corrosive chemicals or extreme temperatures is needed, making them ideal choices for critical filtration applications in industries such as chemical and petrochemical processing. These materials have exceptional resistance to acids, and are used where SS316 or similar materials fail.



How are metallic filters manufactured?

Wound cartridge filters are a type of depth filter commonly used in various industries for liquid filtration applications. They are known for their high dirt-holding capacity, making them suitable for pre-filtration applications and extending the life of other downstream filters in the system.
Working of Wound Filter Cartridge

Powder sintered filters

Filter elements are made using a method called cold isostatic pressing. Here's how it works: metal powder is put into a tool that squeezes it using high pressure. The compact is then taken out of the tool and put in a furnace, where the sintering cycle is carried out.

This makes the metal particles stick together tightly, forming a single, interconnected piece.

Multilayered sintered metal filters

These are made by sintering multiple layers of woven metal mesh kept over each other, and then rolled to the desired thickness. The filtration rating is decided by the pore size of the controlling layer in this case.

he filter element is typically housed in a metal frame for support and protection. The frame may also have connections for attaching the filter to other equipment. In this case, as the pore size is determined by the controlling layer, the limiting factor for the filtration rating is the quality of the weaving and its fineness.

Features of Metallic Filters

  • Metal filters come in various shapes suitable for filtering gases and liquids.
  • Sintered metal filters boast high mechanical strength, and excellent resistance to high temperatures.
  • Regular cleaning and regeneration processes can extend the service life of the filter.
  • For a given porosity, the quality of a filter is determined by its permeability, which is influenced by factors such as porosity, pore size, surface area, and tortuosity of the pore space.

Applications of Metallic Filters

Air filtration

Metal filters are commonly used in air filtration systems to remove dust and other contaminants from air in lab-scale equipment.

Water purification

Metal filters can be used in water purification systems to remove impurities such as sediment, bacteria, and viruses from water. They are often used in homes, water treatment plants, and industrial settings.

Industrial processes

Metal filters are used in a wide variety of industrial processes to remove contaminants from fluids and gases

Automotive engines

Metal filters are used in automotive engines to remove contaminants from oil and air. They help to protect the engine from wear and tear and improve performance.

Flame arrestors

The tortuosity of the channel in powder sintered metal filters lends itself to functioning as a flame arrestor. The flames are not able to travel in this path and so, the gases on the other side are prevented from being ignited.

Silencers

The sound waves are not able to travel tortuous paths of powder sintered metal filters without significant reduction in their amplitude. This is what gives a silencing effect.

Chemical processing

Metal filters are used in chemical processing to remove impurities from chemicals. They help to ensure the quality and purity of the chemicals.

Food and beverage processing

Metal filters are used in food and beverage processing to remove contaminants from food and beverages. They help to ensure the safety and quality of the food and beverages.

Pharmaceutical production

Metal filters are used in pharmaceutical production to remove contaminants from drugs. They help to ensure the safety and purity of the drugs. They are also used to create particle free steam, used for sterilization of pharmaceutical equipment.
