Keeping Seafood or Bait Alive for Market?

We know you need reliable holding & filter systems to keep up with your business goals.

Our robust filters are designed to keep your costs down. AST filters perform both biological and mechanical filtration in one easy-to-use unit with few moving parts for easy maintenance. Now you need less equipment and space to achieve the required filtration with an AST filter.

Holding systems designed with our filters:

  • Increase your holding capacities per unit holding volume
  • Decrease mortality rates
  • Decrease daily water exchange

Engineered for Efficiency

AST filters run off of smaller pumps providing measurable energy savings every month. Our newest filters, the AST Airlift and the Endurance, separate the backwash event from water loss making them great for saltwater applications where you don’t want to be flushing your money down the drain.

The bead media used to filter out solids is food-safe and never needs to be replaced. Let us know your production targets and AST’s filter experts will take care of sizing the filter, tank, and specialty equipment, including heaters or chillers.

Forget the hassle – our filters are easy-to-use, with little maintenance so you can focus on more important things knowing your animals are taken care of.
