This also means that it can be used in applications where large volumes of air must be handled since it does not require regular maintenance. Another advantage of Ryton is its flexibility. Its components are easily assembled and configured, allowing custom-made filters to meet various filtration needs. This can be particularly advantageous when it comes to applications that require filters to meet tight specifications. Furthermore, Ryton has excellent fire and smoke ratings, making it an ideal choice for applications with fire safety requirements.

Overall, Ryton is an extremely versatile and reliable material for filter fabric applications. It is inexpensive, easy to maintain and configure, and can handle various environmental conditions. It is also resistant to many common chemicals, making it an ideal choice for industrial applications.

Disadvantages of Aramid

Aramid, also known as aramid filter fabrics, is a lightweight, synthetic material that is durable and highly resistant to abrasion, corrosion, and exposure to harsh environments. Although these characteristics can make aramid filter fabrics desirable for various applications, some drawbacks must be considered when using this type of filter fabric.

Aramid filter fabrics are not as strong as Ryton filter fabrics. Ryton is stronger and more resistant to abrasion, making it more suitable for many industrial filtration applications. Due to its lower abrasion resistance, aramid filter fabrics can be subject to wear and tear over time. This can reduce their ability to effectively filter out particles, potentially leading to issues with effectiveness and efficiency. Aramid filter fabrics are also less resistant to chemicals than Ryton filter fabrics. They have lower chemical resistance, making them prone to degradation when exposed to certain chemicals or solvents. This can affect the filter’s performance and potentially reduce its useful life.

In addition, aramid filter fabrics can be difficult to fold and pack due to their lightweight construction. This can be an issue during shipping, installation, and use, as the filter fabric needs to be handled and stored carefully to ensure it does not suffer any damage. The cost of aramid filter fabrics is another issue. Although they are more cost-effective than other filter fabrics, aramid filter fabrics can still be more expensive than Ryton filter fabrics. This can be an issue for customers looking for the most cost-effective solution. Overall, aramid filter fabrics can be a great choice for various applications. However, it is important to consider the potential drawbacks before deciding on the best type of filter fabric for a particular application. While aramid filter fabrics offer several advantages, they must be weighed against their potential disadvantages to determine if they are the right choice for your needs.

Disadvantages of Ryton

When compared to aramid filter fabrics, Ryton has some significant disadvantages. The most notable of these is its decreased performance. While aramid filter fabrics can deliver a high-performance filter solution, Ryton falls short in comparison. As such, it is unsuitable for applications requiring a high-performance filtration solution. Ryton also has a lower temperature resistance than aramid filter fabrics. This means it is not suitable for use in applications requiring high-temperature filtration. Additionally, Ryton is not as resistant to some chemicals as aramid filter fabrics, so it may not be the best choice for applications involving certain chemicals.

Furthermore, Ryton is more difficult to work with and install than aramid filter fabrics. It can be more difficult to achieve a tight seal, and it is more likely to experience tearing. In addition, Ryton tends to be more expensive than aramid filter fabrics, which can further limit its desirability. Overall, Ryton falls short compared to aramid filter fabrics and is not recommended for applications requiring a high-performance filtration solution. Its lower temperature tolerance, lack of chemical resistance, difficulty of installation, and higher cost mean it should usually be avoided in favour of aramid filter fabrics.


High-performance filters are essential for protecting and maintaining air quality in industrial, commercial and residential settings.
