How to Solve Industrial Filtration Challenges with Evalith® Micro Fiberglass Filter Tube Media

There’s a broad array of applications in industrial filtration, ranging from oil and gas to sewage treatment, water pretreatment, air filtration, cogeneration facilities, and more. But what they all have in common is that they require high-quality filter media that can withstand tough conditions while ensuring efficiency, durability, and reliability. And this is where micro fiberglass filter tube media comes into play. 

Here at Johns Manville (JM), we produce it from biosoluble microfibers bonded with a thermoset resin. With its seamless design and customizable specifications, Evalith® micro fiberglass filter tube media provides industries with efficient, long-lasting filtration performance and exceptional contaminant removal. 

Meeting the Challenges of Industrial Filtration

Industrial processes often involve high temperatures, corrosive environments, and stringent contamination control requirements. Many filtration media struggle to maintain consistent performance under these conditions, leading to frequent maintenance, increased costs, and operational inefficiencies. 

“Our customers are looking for filtration solutions that are not only efficient but also reliable over time,” explains Dr. Joerg Meier, Product Development Leader of JM’s Global Filtration & Separation business. “With Evalith® micro fiberglass filter tube media, we deliver a product that ensures stable filtration efficiency, reducing downtime and optimizing total cost of ownership.”

The seamless design of the filter media eliminates potential leakage paths and ensures zero shrinkage, exceptional corrosion resistance and predictable, repeatable performance. Its high permeability and dirt-holding capacity make it a powerful choice for industrial applications that demand robust contaminant removal. Additionally, with a moisture sorption rate below 5% by weight, the tubes resist humidity and do not accelerate corrosion, extending their usable life. 

Designed for Performance and Adaptability

Filtration needs vary significantly across industries, requiring solutions that can be tailored to specific applications. JM offers customizable options, including:

✅ Wall thickness

✅ Inner and outer tube diameters

✅ Loss on ignition (LOI)

✅ Density 

According to Jim Dolgoff, Key Account Manager, customization is a key advantage for customers:

“We recognize that no two industrial processes are the same. That’s why we work closely with our clients to provide filter tube media with precise specifications that match their operational needs. Whether they require reduced thickness or optimized density for better pressure drop, our solutions help them achieve maximum efficiency.”

The Evalith® filter tube media is designed for high-temperature applications, capable of withstanding up to 850°F (455°C), making it ideal for use in extreme environments. 

Supporting Customers in Their Sustainability Goals

As industries shift towards more sustainable practices, filtration solutions must align with environmental responsibility. Evalith® micro fiberglass filter tube media integrates an average of 25% post-consumer recycled glass content, contributing to waste reduction and circular economy efforts. Additionally, the biosoluble nature of the microfibers adds further eco-friendly credibility, making the filter tube media an excellent option for organizations emphasizing sustainability.

“We understand the evolving needs of our customers and the sustainability requirements they aim to meet,” added Jim Dolgoff. “By designing filtration media that is both highly durable and environmentally responsible, we help them reduce their carbon footprint while maintaining the highest levels of filtration efficiency.”

Innovation & Customer Collaboration

With manufacturing facilities in the United States and Germany, we ensure consistent product quality and global availability, providing customers with the technical expertise and support they need to optimize their filtration systems. Furthermore, JM continuously invests in R&D and customer collaboration to develop cutting-edge filtration solutions that address the evolving needs of industrial applications. 

We will be showcasing our wide range of glass but also synthetic filter media at FiltXPO in Miami Beach, FL, USA (April 29–May 1, 2025).
