20-Inch (BB) Wound Filter Cartridge (1 Micron)

Ultra-Fine 20-Inch (BB) Wound Filter Cartridge (1 Micron) for Large Scale Systems

The 20-Inch BB 1 Micron Wound Cartridge is the professional choice for situations requiring extreme water clarity at high volumes. While standard filters often clog quickly when dealing with fine mud or “red water” rust, the string-wound design uses a precision-wrapped pattern that is looser on the outside and tighter toward the core. This “true depth filtration” allows the cartridge to absorb massive amounts of debris before requiring a change.

Key Features & Benefits:

• Exceptional Fine-Particle Capture: The 1 micron rating is tight enough to remove microscopic sediments, protecting sensitive downstream components like Reverse Osmosis (RO) membranes, UV sterilizers, and high-end plumbing fixtures from abrasive damage.

• Massive Dirt-Holding Capacity: Because of its Big Blue (4.5″) diameter, this cartridge can hold several times more sediment than a standard 10-inch or slim filter, making it perfect for the heavy sediment loads often found in Sri Lankan borehole and municipal water.

• High Flow Performance: Engineered to minimize pressure drop, it maintains a steady, powerful water flow even in large mansions, apartment buildings, or small factories.

• Chemical & Heat Resistance: Made from 100% Food-Grade Polypropylene, it is resistant to bacteria, chemicals, and temperatures up to 60°C – 74°C, ensuring no odors or fibers are released into your water supply.

• Structural Strength: The yarn is wound around a reinforced polypropylene core, preventing the filter from bypassing or collapsing during sudden pressure spikes.

Typical Applications:

• Whole-House POE: Point-of-Entry filtration for large luxury homes and villas.

• Commercial Pre-Filtration: Primary stage for high-volume RO plants (500LPH+), hotels, and beverage plants.

• Borehole & Rainwater: Specifically effective at removing the fine “silt” and clay particles common in untreated water.
