Waterco Opal Cartridge Filters — Opal 135 · Opal 180
Minimal fuss, maximum clarity
The Waterco Opal Cartridge Filter is designed to eliminate the hassle of media-based filtration. The pleated reusable cartridge delivers high surface area for efficient dirt capture, meaning fewer cleanings and longer intervals between maintenance. Built tough with a polypropylene tank and easy-access screw-on lid, Opal makes pool care simple and durable.
Ideal where backwashing is difficult or water conservation is important, these filters perform under pressure and with low maintenance demands. With working pressures up to 250 kPa, temperature ratings as low as 4°C all the way to 50 °C, and high flow capacity, Opal keeps your pool sparkling without over-engineering.
- Pleated, reusable polyester cartridge with high dirt holding capacity (12.5–16.7 m²) to reduce cleaning frequency.
- Screw-on lock-ring lid for fast cartridge removal and cleaning.
- No sand, DE or media — just cartridge filtration. Cleaner, simpler, less mess.
- High maximum flow rates (~510 L/min) and large pool size capacity (~183,600 L) for Opal 135 and Opal 180.
- Solid, high-impact polymer tank built for rugged conditions.
- Built-in pressure gauge & air relief valve to help maintain optimal filtration performance.
