Aqua Max 4-Bag Sand Filter

The Aqua Max 4-Bag Sand Filter provides mechanical filtration for larger residential swimming pools up to 90,000 litres. Water passes through 160kg of filter sand inside the 610mm diameter tank, trapping dirt, debris, and particles down to approximately 20 microns. The larger sand bed handles higher flow rates and heavier debris loads from bigger pools.

Specifications

Tank diameter: 610mm. Sand capacity: 160kg (4 bags of 40kg filter sand). Pool size rating: up to 90,000 litres. Valve: 6-way multiport valve included (filter, backwash, rinse, waste, recirculate, closed). Tank material: roto-moulded polyethylene — one-piece construction, no seams. Available in black and grey.

Recommended Pump Pairing

Pair with a 1.1kW pool pump for optimal flow rate and filtration performance. Oversizing the pump pushes water through the sand bed too fast and reduces filtration quality. The Aqua Max 1.1kW pump is the ideal match for this filter.

Maintenance

Backwash when the filter pressure gauge reads 80-100kPa above the clean starting pressure, or at least once a week during swimming season. Replace filter sand every 5-7 years or when water clarity deteriorates despite regular backwashing.
