  • AST - Polygeyser Endurance 4000 Filter


    All in one filter- providing both solids removal and ammonia conversion for excellent water quality and crystal clear water.

    2 cubic foot of AST filtration media

    • 25gpm

    • 2000-4000 gallon systems (ponds or tanks)

    • Features

      • Automatic pneumatic backwash- uses air pressure to periodically wash the filter bed and automatically capture solids in the sludge chamber

    Saves time and labor. Longer periods between routine maintenance and sludge capture

      • Lowest water loss filter in the industry- low water loss when directly removing sludge and fish waste

      • Large sludge storage chamber- reduces routine maintenance

      • Superior solids removal and biofiltration- AST filtration in unequalled in the aquaculture recirculating systems with over 20 years in the industry. Capturing micro-solids down to 10 microns in size.  Large surface area for bacterial culture and ammonia conversion.  Unique media design prevents scouring and protects bacteria and secondary, beneficial filter microorganisms.

      • Low profile design- small footprint saving overall design space

      • Minimal energy costs-Airlift driven installation creates the most efficient aquaponics or aquaculture recirculating systems in the industry.

      • Perfect for koi ponds, home aquaculture, and aquaponics systems
