AST Endurance 4000 Bead Filter

AST Endurance 4000 Bead Filter

The AST Endurance 4000 Bead Filter is a premier filtration solution designed for pond owners who demand crystal-clear water with minimal maintenance. Engineered by Aquaculture Systems Technologies, the Endurance series revolutionizes bead filtration by eliminating the need for a noisy air blower. Its innovative design utilizes a patented internal backwash process that effectively breaks up the bead bed and removes trapped solids without the mechanical complexity or energy consumption of traditional blower-assisted systems.

This filter provides exceptional dual-stage filtration, acting as both a mechanical trap for fine debris and a high-capacity biological reactor for beneficial bacteria. The Endurance 4000 is specifically optimized for ponds up to 4,000 gallons, providing a healthy environment for koi and other ornamental fish. With its heavy-duty, UV-resistant construction and simple multi-port valve operation, this filter is built to provide decades of reliable service while making the "dirty work" of pond maintenance as easy as turning a handle.

Features:

• Blower-Free Design: Patented internal components allow for thorough backwashing without the need for an external air blower.

• Superior Water Clarity: Provides excellent mechanical filtration, stripping fine solids from the water column.

• High Bio-Capacity: The bead media provides a massive surface area for nitrifying bacteria to colonize.

• Low Maintenance: Simple backwash procedure takes only minutes and keeps your hands dry.

• Energy Efficient: Designed for low backpressure, allowing you to use more efficient, lower-wattage pumps.

• Heavy-Duty Construction: Features a robust, corrosion-proof vessel designed to withstand high pressure and outdoor elements.

• Clear Sight Glass: Includes an integrated sight glass to easily monitor the discharge water during the backwash cycle.
