Astral ECA Media Filter Range
Reliable, Economical Sand Filtration for Aussie Pools
Designed and manufactured in Australia, the Astral ECA Media Filter range delivers crystal-clear water for residential pools and spas up to 120 kL. Each injection-moulded tank is built to handle harsh UV, fluctuating water chemistry, and daily back-washing with ease, while the six-way multi-port valve makes maintenance a breeze.
Compatible with silica sand, recycled glass, or Zeolite media, the ECA series provides flexible, low-cost filtration and pairs perfectly with modern variable-speed pumps for lower running costs.

Q1: Which ECA model suits my pool size?
Match your pool volume to the “6 hr Turnover” figures. For example, a 70,000 L pool suits the ECA550, while anything closer to 120,000 L pairs with the ECA650.
Q2: Can I switch from sand to glass media?
Yes. Both ECA models accept recycled glass, providing finer filtration and lower back-wash water usage.
Q3: Is the ECA filter compatible with salt or mineral pools?
Absolutely. The tank and valve are corrosion-resistant and UV-stabilised, making them ideal for saltwater, magnesium, and chlorine systems.
