AST Endurance 4000 Bead Filter Kit

The AST Endurance 4000 Bead Filter Kit provides a comprehensive, all-in-one filtration solution for ponds and tanks up to 4,000 gallons. This kit builds upon the industry-leading Endurance 4000 filter by including all the essential components needed for a professional installation. Featuring patented PolyGeyser technology, the system provides automatic pneumatic backwashing, allowing the filter to operate for extended periods without manual intervention. This makes it an ideal choice for koi ponds, aquaponics, and grow-out tanks where consistent water quality and low labor are priorities.

By utilizing an air-powered backwash cycle, the Endurance 4000 eliminates the need for expensive, high-maintenance water pumps or noisy air blowers typically found in traditional bead filters. The kit includes a high-quality linear air pump and an adjustable flowmeter to give you precise control over backwash intervals. With no moving internal parts and media that never needs to be replaced, this kit offers a "set it and forget it" level of reliability that guarantees crystal-clear water and a healthy aquatic ecosystem.

Features:

Automatic Pneumatic Backwash: Operates for extended periods without manual cleaning, saving time and labor.
Complete Professional Kit: Includes the filter, air pump, enhanced bead media, and all necessary fittings for immediate setup.
Lowest Water Loss: Industry-leading efficiency, losing less than 5% of the water used by traditional filters during cleaning.
Dual Filtration: Provides superior mechanical solids removal and biological filtration in a single compact unit.
Blower-Free Technology: Uses air pressure for backwashing, eliminating the need for complex internal moving parts or external blowers.
Crystal Clear Results: Engineered to deliver high-clarity water for sensitive koi and aquaponic systems.
Energy Efficient: Low-profile design allows for "airlift" water pumping, significantly reducing monthly energy costs.

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

Aquaponics Applications:

They also work beautifully for aquaponics applications.

The Endurance filters separate out solids in the water and store them in a large sludge chamber. The integrated chamber allows partial mineralization for plant nutrients. This nutrient rich water can then be automatically released to plant grow beds as part of the backwash process. The amount of water and delivery frequency can be easily adjusted to keep your nitrate levels ideal for fruiting or green growth.

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.
