What Is MINIMESH® Filter Cloth? (Definition, Types, and Customization)
At W.S. Tyler we talk a lot about our knowledge of woven wire mesh. It’s the heart of our business and something that is used in industries all over the globe.
As our wire mesh filter solutions have been used for over 100 years, we strive to develop new weave patterns and types of woven wire mesh that offer optimal filtration in terms of durability and precision.
In 1954, a special Minimesh weave of ours was used in Nasa’s aviation and space programs and enabled smoothly functioning control systems and engine units.
Since then, our Minimesh wire mesh filter has become one of our most reliable and trusted products in woven wire mesh industry.
In this article, we are going to talk about the benefits of using Minimesh wire mesh filters over other media like paper or plastic. We are also going to talk about how it compares to plain weave or more standard square mesh patterns.
What Is Mesh Filter Cloth?
When it comes to wire mesh filters, W.S. Tyler specializes in two different types: Square Mesh and Minimesh Filter Cloth.
Square mesh is your typical “over-under” pattern, otherwise known as plain weave.
Minimesh is W.S. Tyler’s brand name for all 7 of our wire mesh filter cloth weave types in this product line. All of these weaves are more intricate and precise than you will find in a square mesh pattern.
Minimesh can be used in situations where tremendous pressure or intensity is applied during the filtration process where paper, plastic or square stainless steel woven wire mesh may not hold up. It’s used in a wide variety of applications like filtration, fluidizing, drying, and screening.
Minimesh micron ratings range from 7 microns 302 microns.
To strengthen the Minimesh material further a multilayered material is introduced, known as Porostar. Porostar is created by annealing layers of mesh together to protect the innermost, finest filter layers.
What Are the Benefits of Minimesh?
There are many benefits to using Minimesh in your application such as clean-ability, low blinding, precise cut point, durability, and a long lifespan.
Cleaning your filter media is an important part of any filtration system. This ensures you are getting accurate results each time. One of the benefits to Minimesh is that it is easy to clean and maintain.
Minimesh is so durable and strong that back cleaning or flushing can be used to properly clean it between uses. This type of cleaning is not always possible with other filter media like paper or plastic because they will not hold up to the pressure.
The geometric filter structure is uniform throughout the entire area in Minimesh. This is much more accurate than paper, metal or plastic materials for filtration.
Minimesh is woven in a very precise way. This creates a level of consistency and accuracy when using the mesh. It is also woven in a cleanroom, temperature-controlled environment.
High Flow Rate
One of the things we are most proud of when it comes to our Minimesh is its flow rate. We have worked hard to develop a media that is efficient and durable.
We want to spend a little time diving into the technical aspects of how flow rate is determined.
When a fluid flows through a filter medium, a pressure difference is generated between the inlet and outlet sides. This is dependent upon the structural properties of the filter, the load, and the properties of the fluid.
Even with a small pore opening, Minimesh wire mesh filter cloth achieves a high flow rate with a low-pressure drop, which contributes to greater energy efficiency and cost-effectiveness throughout the filtration process.
Low Blinding Tendencies
Blinding is when particles get stuck in the openings in mesh and stop other particles from passing through. This is something we deal with often in the filtration world. While there are ways to help combat this problem, Minimesh filter cloth naturally eliminates a lot of that issue.
The way Minimesh is woven creates less blinding during application. You have a higher flow rate when you use Minimesh wire mesh filters over another method of filtration, which we talked about earlier. This helps particles seek openings faster, stopping build up and blinding from happening.
Minimesh is constructed of mostly 304 or 316 stainless steel. Other alloys are available upon specific request, but the stainless steel used in Minimesh is what makes it so durable and long-lasting. You can learn more about the material we use for Minimesh here: Types of Wire for Minimesh.
Minimesh can be molded and formed. It is able to withstand pressure in a filter system that other types of filtration methods couldn’t without damaging the material or sacrificing accuracy.
Resistance to Temperature and Chemicals are also both major benefits to the metallic nature of Minimesh.
Because Minimesh is so durable and reliable, you will not be damaging and replacing it as often in comparison with other types of filtration media. This will result in less downtime for your process as well as less money spent on potential replacements.
Customizations, Added Processes, Research and Development
Now that you may have a better understanding of the material by itself, we can get into some of the value-added capabilities to suit your individual needs. This is a product that is customizable into different sizes and shapes.
The filter can be customized into something as complicated as a multilayered filter or as simple as a cut to size sheet. If you know your exact requirements for the filter, then the next steps are as simple as working with our engineering team to price out the project. If you are working on a new filter and not sure of the exact needs for the filter, our research and development team can help you develop the filter to achieve your goals.
We have detailed pages on our website with more of the technical information including specs and photos. For this article, we wanted to keep it simple, but if you are interested in that level of info you can click on each type of weave below to see its unique characteristics and the technical info.
How to Know Which Weave Type Is Right for You?
We like to work with every customer to help them find the right material for them. The two things that are going to lead you to the right weave type for you are pore size and pressure in your system.
This graph was designed to help you determine which weave type is right for you based on those two properties.
