Description
The BlueSpot Water String Wound Filter Cartridge is a high-performance sediment removal solution designed for challenging water conditions. Unlike standard melt-blown filters, this cartridge utilizes a unique yarn-woven design to provide genuine depth filtration.
Features
-
True Depth Filtration: The precision-woven yarn pattern creates a gradient that traps up to 99% of particulates including sand, silt, dirt, and rust.
-
Borehole Ready: Specifically engineered for water with high sediment loads, preventing premature clogging compared to surface-style filters.
-
Extended Service Life: The deep-groove structure allows the filter to hold significantly more dirt, leading to longer intervals between replacements.
-
Broad Compatibility: Available in all common sizes (10", 20", Slimline, and Big Blue) to fit standard South African filter housings.
-
High Flow Efficiency: Designed to maintain optimal water pressure even while capturing fine debris.
How It Works
-
Depth Capture: As water flows through the woven yarn, larger particles are trapped on the outer surface while finer particles are caught deeper in the winding toward the center core.
-
The Result: Cleaner water and superior protection for downstream appliances, pumps, and sensitive carbon or RO filters.
| Model Size | Max Flow Rate | Approx. Service Life | Max Pressure |
| 10" Standard (Slim) | 20 L/min (5 GPM) | 20,000 Litres | 8.6 Bar |
| 10" Big Blue (Fat) | 40 L/min (10 GPM) | 40,000 Litres | 8.6 Bar |
| 20" Standard (Slim) | 40 L/min (10 GPM) | 40,000 Litres | 8.6 Bar |
| 20" Big Blue (Fat) | 80 L/min (20 GPM) | 80,000 Litres | 8.6 Bar |
Maintenance
To ensure continuous protection for your water system:
-
Replacement Interval: Replace every 6 – 12 months depending on source water quality and visual dirt buildup.
-
Borehole Usage: Highly turbid water may require more frequent changes if a decrease in flow is noticed.
-
Temp Guide: Recommended maximum operating temperature within the housing is 52°C.
