AstralPool CA Media Filter Range
Engineered for Crystal-Clear Water in Tough Australian Conditions
Made and tested in Australia, the AstralPool CA Media Filter range delivers sparkling, healthy pool water while withstanding our harsh UV, heat and salt-rich environments. Each tank is fully injection-moulded for maximum strength, then paired with AstralPool’s premium 6-way multi-port valve and 10-lateral under-drain to keep pressure loss ultra-low—even when you upgrade to energy-saving variable-speed pumps.
Why Choose the CA Series Over Ordinary Sand Filters?
Traditional filters struggle with water clarity, back-washing inefficiencies and early tank failure. The CA series solves these pain-points by:
- Cutting energy consumption thanks to a flow-optimised under-drain that reduces pump workload by up to 30%.
- Shortening back-wash times—saving thousands of litres of water every season.
- Accepting multiple filter media types (high-grade silica sand, recycled glass or Zeolite) so you can tailor performance and sustainability.
- Offering a market-leading 10-year tank warranty and 12-month valve & internals warranty for true peace of mind.
Sized for Every Residential Pool
With four active models—CA280, CA300, CA340 and CA400—the CA range covers pools from small courtyard plunge pools right through to large family pools of ~190 kL. Simply match your turnover requirement (see table below) to pick the perfect model.
Built for Modern, Energy-Efficient Set-ups
The CA’s quick-lock ring and barrel-union ports make installation painless, and 40 mm or 50 mm connections integrate seamlessly with today’s variable-speed and inverter pumps. Pair with AstralPool’s Viron Active Glass for best-in-class micron filtration and noticeable sparkle.

Frequently Asked Questions
Q1: Which CA model suits my pool size?
Match the litres your pool turns over in six hours to the “6 hr Turnover” column above. For example, a 75,000 L pool pairs perfectly with the CA280, while pools above 150 kL benefit from the CA400.
Q2: Can I run glass media instead of sand?
Absolutely. The CA range is optimised for both high-grade silica sand and recycled crushed glass. Glass offers finer filtration (down to 3 µm) and needs 20–25% less back-washing.
Q3: How often should I back-wash?
Under normal residential use, back-wash when the pressure gauge rises 8–10 kPa above the clean reading—typically every 4–6 weeks in peak season.
