3-Sintered Filter How It Works

How It Works

The sintered filters working principles are suitable for a variety of applications. For example, it can filter substances, even particles. They can completely separate solids from gases and liquids.

It’s also capable of regulating the air stream. The uniform sintered filters’ pore size enhances consistency and control of an air passage. Most manufacturing industries, relatively for vehicles, use this as a gas supply control.

However, it’s essential to note that the working principle depends on what is required. Other alternatives to the working principle varied on the application needed.

5-Sintered Filter Rating VS. Pore Size

Filter Rating VS. Pore Size

Filter rating and pore size are both important characteristics of sintered filters.

The filter rating indicates the size of particles that a filter can capture and retain, typically measured in microns.

Pore size, also measured in microns, refers to the size of the openings or pores within the filter material itself.

While there is a correlation between the two, it’s important to consider both factors when choosing a filter for a specific application.

Understanding the relationship between filter rating and pore size helps in selecting the appropriate sintered filter that can achieve the desired particle capture efficiency while allowing for adequate flow of the desired fluids or gases.

Frequently Asked Question

No, but it’s necessary to be precise about the details from a manufacturer. Other than that, sintered filters are simple to clean.

  • Heat them for 2 hours at 380 degrees Celsius for best results in a nitrogen-protected furnace.
  • After that, use an ultrasonic machine for another 30 minutes.

However, it’s essential to be cautious in cleaning the porous parts.

  • To remove any remaining dirt and grime, wash them under running water.
  • Turn the water’s flow in both directions several times through the filters.
  • For better cleaning, consider using a vacuum.

Yes. There is a variation of sintered filters available.

The most common one is called sintered porous metal filter elements. It has a type of pores structure ideal for high-pressure and mechanically-tolerant filtration.

And another typical type has a pleated structure. It stands based on a name pleated sintered metal filter. The large surface area captures substances that pass through a filter of this type.

The sintered powder metal filters are cost-effective due to their stable and reusable advantages.
