Technical Specifications

Our stainless steel pleated filter cartridge is meticulously designed with precise specifications to ensure reliability across diverse applications. Below is a comprehensive table outlining key technical parameters.

Application Scenarios

The versatility of the stainless steel pleated filter cartridge makes it indispensable in numerous industrial sectors. In water treatment plants, it excels at pre-filtration and security filtration, removing suspended solids from municipal and industrial wastewater to protect downstream RO membranes and ensure ultra-pure output.

Food and beverage processors rely on it for clarifying juices, wines, and edible oils, meeting hygiene standards while preserving product flavor and clarity. In the pharmaceutical industry, its cleanable design supports sterile filtration of injectables, APIs, and solvents, complying with GMP and USP Class VI requirements.

Chemical manufacturing benefits from its resistance to harsh reagents, filtering corrosive liquids and gases to prevent equipment damage and maintain process purity. Oil and gas operations use it for fuel polishing, lube oil filtration, and produced water treatment, handling high-viscosity fluids under pressure.

Additionally, electronics and semiconductor fabs employ the cartridge for DI water production and chemical bath recirculation, where sub-micron filtration is critical. Power generation plants integrate it into cooling water systems and turbine lube oil circuits, enhancing efficiency and reducing downtime.

Advantages

Choosing a stainless steel pleated filter cartridge delivers tangible benefits over disposable or lesser materials. Its robust stainless steel framework ensures a lifespan 5-10 times longer than polymer alternatives, slashing replacement costs and waste generation for sustainable operations.

The pleated structure provides unmatched filtration efficiency, capturing 99.9% of targeted particles while supporting high throughputs—up to 50% more than cylindrical filters. This translates to lower energy consumption via reduced pump strain and minimal pressure differentials.

Reusability is a standout advantage: simple ultrasonic cleaning or backflushing restores performance to near-original levels, ideal for high-volume or continuous processes. Corrosion-proof properties eliminate frequent inspections and failures in aggressive environments, boosting uptime.

Furthermore, precise manufacturing tolerances guarantee drop-in compatibility with standard housings like Code 7 or 222 O-rings, simplifying retrofits. Certified for food contact and ATEX zones, it supports global compliance and risk mitigation.
