ECA650 Sand Filter
Designed for residential pools and spas. The ECA650 is ideal for conventional above-ground pools and small- to medium-sized in-ground pools where reliable everyday filtration is the priority. Its larger filter area compared to the ECA550 allows it to comfortably support higher water volumes and stronger circulation systems.
Built for long-term durability. Manufactured using injection moulded high-strength materials, the ECA650 is designed to withstand harsh Australian outdoor conditions. The robust tank construction helps deliver long service life with dependable structural strength over time.
Efficient filtration for sparkling clear water. The ECA650 uses the same high-quality manufacturing principles found in AstralPool’s larger filter systems. With engineered internal flow design and proper media capacity, it helps maintain clean, balanced pool water with efficient filtration performance.
Simple maintenance and easy servicing. The ECA650 is designed to reduce maintenance complexity. Features such as corrosion-free valve connections, oil-filled pressure gauge, and fast-draining water and filter media systems help simplify servicing and reduce long-term maintenance costs.
Made in Australia for Australian conditions. Designed and manufactured locally, the ECA650 is engineered specifically for Australian residential pool environments and operating conditions.

For best performance, the filter should be properly matched with the pool pump flow rate, pool volume, chlorinator, and overall circulation system by a qualified pool technician.
Installation & Maintenance
The Astral ECA650 should be installed by a qualified pool technician following Australian plumbing and filtration standards. The filter should be mounted on a stable, level surface with sufficient space for valve access, servicing, and media replacement.
Correct filter media selection and loading are important for achieving proper filtration performance. The system should also be backwashed regularly based on pressure readings and pool usage levels.
Routine maintenance is straightforward. The oil-filled pressure gauge helps monitor filter performance, while the corrosion-resistant valve connections and fast-drain system simplify cleaning and servicing. Periodic media replacement will help maintain optimal filtration efficiency over the life of the filter.
