AAL-PMF Pleated Metal Felt Filter Cartridge: Robust Filtration for Extreme Conditions

Product Overview

The AAL-PMF Pleated Metal Felt Filter Cartridge is a high-surface-area, stainless steel sintered fiber filter designed for heavy-duty industrial filtration in high-temperature and high-viscosity environments. Offering exceptional durability and efficiency, it’s the ideal solution for demanding filtration challenges.

What Are Metal Filter Cartridges?

Metal filter cartridges are engineered for harsh conditions where conventional filters falter, such as high temperatures, high pressures, corrosive media, or applications requiring cleanability and reusability. Typically made from 316L or 304 stainless steel, they can also incorporate titanium for enhanced corrosion resistance and mechanical strength in extreme settings.

AAL Filter’s Metal Series

The AAL-PMF series from AAL Filter is crafted to address specialized industrial filtration needs. By leveraging premium stainless steel sintered fiber felt and precision pleating technology, combined with an all-metal construction, these cartridges deliver reliable, reusable, and high-performance filtration tailored for rigorous applications.

What Is the AAL-PMF Pleated Metal Felt Cartridge?

The AAL-PMF cartridge utilizes stainless steel sintered fiber felt as its core filter media, pleated to maximize filtration surface area and achieve absolute filtration precision. This porous, depth-type filter media is produced by sintering stainless steel fibers at high temperatures, ensuring exceptional mechanical strength and thermal stability.

Featuring an all-stainless steel design, the AAL-PMF offers broad chemical compatibility, withstanding high temperatures, pressures, corrosion, and oxidation. Its multi-layered structure includes a reinforcement layer, protective mesh, and primary filtration layer, creating a robust system capable of enduring prolonged operation in harsh conditions.

A defining feature of the AAL-PMF is its graduated pore structure, transitioning from coarser upstream pores to finer downstream pores. This design significantly enhances dirt-holding capacity and extends service life by progressively capturing impurities of varying sizes.

Product Highlights

1️⃣ All-Stainless Steel Construction: Resists corrosive chemicals and thrives in high-temperature, high-pressure environments.

2️⃣ High Porosity & Low Pressure Drop: Optimizes flow rates and extends equipment lifespan.

3️⃣ Cleanable & Reusable: Supports chemical, backwashing, high-temperature, or ultrasonic cleaning for cost-effective durability.

4️⃣ Multi-Layer Gradient Filtration: Coarse-to-fine pore distribution boosts dirt-holding capacity and filtration efficiency.

5️⃣ Ideal for Viscous Fluids: Excels in filtering syrups, colloids, oils, and other high-viscosity media.

6️⃣ High-Temperature Resilience: Operates reliably up to 500°C in extreme thermal conditions.
