The AST Endurance™ Filter is an advancement of our patented PolyGeyser® technology with the addition of many new enhancements and increased performance features.

Features Include:

  • Automatic pneumatic backwash enabling the filter to operate for extended periods of time without intervention, saving time and labor
  • Lowest water loss filter in the industry, less than 5% of traditional filters
  • Large sludge storage chamber that concentrates the sludge minimizing servicing needs
  • Superior solids removal and biofiltration in one filter, delivering crystal clear water
  • Low profile design allows for “airlift” water pumping, minimizing energy costs
  • Elegant, simple design with no moving internal parts and no replacement media ever required, guaranteeing trouble free operation
  • Units arrive pre-filled with bead media which never needs replaced

Optional Add-Ons:

  • Optional automatic sludge discharge making the filter virtually maintenance free
  • Optional UV light add-on to assure algae control even under warm water conditions

A Little Workhorse

AST Endurance filters are ideal for ponds or tanks 200 to 4000 gallons in size and are designed for use in KOI, Aquaponic, Fingerling and small Growout applications. The tables below shows the approximate sizes of ponds, tanks and aquaponic systems the Endurance models will support.

Endurance Operation: Standard Configuration

These exceptional filters backwash automatically, several times a day. The user does not need to turn off the pump or close any valves during the backwash sequence. The filter does not require an electric timer. The backwash cycle is regulated by the air that is injected into the charge chamber. The filters clean and recycle the dirty water produced in backwashing every two to three hours. Sludge is only removed once or twice a week.
