4.5x10" Water Filter String Wound Cartridge,5 Microns

Heavy-Duty Filtration – 4.5"x10" String Wound Water Filter Cartridge

The 4.5"x10" String Wound Cartridge is engineered to deliver reliable sediment removal in residential, commercial, and light industrial water systems. Constructed with polypropylene yarn precision-wound onto a reinforced core, this cartridge provides depth filtration capable of capturing fine particles while maintaining strong flow rates.

Professional Advantages

• Depth Filtration Design – Captures particles throughout the entire filter structure for longer service life compared to surface filters.
• 5 Micron Nominal Rating – Effectively reduces sand, rust, scale, and other suspended solids.
• Durable Polypropylene Construction – Resistant to chemicals and corrosion, ensuring compatibility with a wide range of water systems.
• Large Diameter Format – 4.5" big blue sizing provides extended dirt-holding capacity, reducing maintenance frequency.
• System Compatibility – Designed to fit standard 4.5"x10" filter housings, including DP BIG models.

Technical Specifications

• Dimensions: 4.5" x 10"
• Micron Rating: 5 Micron nominal
• Core Material: Polypropylene
• Media: Polypropylene yarn, string wound
• Application: Sediment filtration in residential, commercial, and industrial water systems

Installation Notes

Installation of the string wound cartridge is straightforward, requiring only proper housing preparation and O-ring lubrication. For best results, flush the system after installation to remove any loose fibers. While DIY users may complete the changeout, contractors should ensure system pressure is relieved and fittings are secure before returning equipment to service.

Contractor Considerations

For HVAC/Plumbing Professionals: The cartridge’s high dirt-holding capacity reduces service intervals, making it ideal for maintenance contracts and high-use environments. Its chemical resistance also provides flexibility for non-potable applications.

For Facility Managers: Regular replacement ensures consistent water clarity, protects downstream equipment, and minimizes scaling or fouling of critical components.

Performance Highlights

• Depth Filtration – Progressive density captures larger particles on the outside and finer particles toward the core.
• 5 Micron Rating – Suitable for most sediment pre-filtration needs.
• NSF-Grade Polypropylene – Non-toxic, safe for potable water systems.
• Extended Lifespan – Large diameter reduces replacement frequency.

The 4.5"x10" String Wound Cartridge provides robust, professional-grade sediment removal for demanding water applications. Built to last and engineered for consistency, it remains a standard solution where reliable water quality is essential.
