What are the pleated filter materials?

The pleated filter cartridge consists of the filter outer cage, support part, filter membrane, and filter inner core. The common pleated filter membrane materials include PP, PES, PVDF, PTFE, PFA, fiberglass, Nylon, etc.

Are pleated filters reusable?

Depends on the filter materials. Generally, pleated filters are not intended for repeated use, especially in applications where they are exposed to high levels of contaminants. The pleats in these filters provide a large surface area for effective filtration, and over time, they can become clogged with particles, reducing their efficiency.

There are some specialized pleated filters designed for reuse, these filters are typically made from materials that can withstand cleaning processes, such as polyester or other synthetic materials. But please keep in mind that even washable pleated filters have a limited number of cleaning cycles before they may need replacement.

What is the main advantage of a pleated filter?
  • Increased Surface Area: Pleated filters enhance surface area for filtration, ensuring optimal particle capture without compromising airflow, resulting in an extended lifespan.
  • Reduced Pressure Drop: These filters provide lower resistance to airflow, leading to reduced pressure drop and, consequently, lowered filtration costs.
  • Enhanced Dirt Holding Capacity: The pleated design allows for a higher capacity to hold dirt, minimizing the frequency of cartridge replacements and contributing to cost savings.
  • Improved Particle Removal Efficiency: Pleated filters exhibit increased efficiency in removing particles, ensuring a cleaner and more purified filtration process.
  • Higher Loading Capacity: The design of pleated filters allows them to handle a higher load of contaminants, maintaining efficiency even in challenging operating conditions.
  • Greater Durability: Pleated filters are known for their durability, providing a longer service life and increased resilience in diverse environmental conditions.
  • Superior Filtration Efficiency: Overall, pleated filter cartridges deliver superior filtration efficiency, making them a reliable choice for various industrial and environmental applications.
What is the use of pleated filter?

The pleated filter is a filter cartridge with a pleated structure filter medium. Pleated filters find applications in various industries such as pharmaceuticals, electronics, microelectronics, semiconductors, water, oil, food, beverage, etc.

What is a code 3 filter?

Code 3 filter is the pleated filter that uses a 222 adapter(with two 222 ‘O’ rings) at the open end and a flat blanking cap at the closed end. This type of filter is widely used in liquid industry filtration.

Pleated Filter Cartridge Code 3

What is a code 7 filter?

Code 7 filter is the pleated filter that uses a 226 adapter(with two 226 ‘O’ rings) with a double bayonet fitting at the open end and a fin at the closed end.

Pleated Filter Cartridge Code 7

What is the difference between a media filter and a pleated filter?

Media filters and pleated filters are two types of filters commonly used in various industrial applications. The main differences between them lie in their construction and filtration capabilities:

Media FilterPleated Filter Cartridge Code 3

  1. Construction:
    • Media Filter: A media filter typically consists of a flat or extended surface composed of a filtering media, which can be fiberglass, polyester, cotton, or other materials. The filter media is contained within a frame or cardboard box.
    • Pleated Filter: A pleated filter, on the other hand, has a design that includes pleats or folds in the filter media. Pleated filters are often made with materials like polyester or synthetic blends.
  2. Surface Area:
    • Media Filter: Media filters generally have a flat or extended surface, providing a relatively larger surface area for filtration.
    • Pleated Filter: Pleated filters leverage the pleats to increase the surface area significantly compared to a flat media filter of the same size.
  3. Filtration Efficiency:
    • Media Filter: Media filters can vary in filtration efficiency depending on the type of media used. They are available in a range of efficiencies, including basic, standard, and high-efficiency options.
    • Pleated Filter: Pleated filters often offer higher filtration efficiencies compared to flat media filters. The pleats provide more opportunities for capturing and retaining particles.
  4. Resistance to Airflow:
    • Media Filter: Flat media filters generally have lower resistance to airflow, which means they may allow for better airflow through the system.
    • Pleated Filter: While pleated filters can have higher filtration efficiencies, they may also have higher resistance to airflow due to the increased density of pleats.
  5. Application:
    • Media Filter: Media filters are commonly used in residential HVAC systems and light commercial applications.
    • Pleated Filter: Pleated filters are used in both residential and commercial HVAC systems. They are often preferred in applications where higher filtration efficiency is required.
