OASE BioTec ScreenMatic2 39000 Filter

OASE BioTec ScreenMatic2 39000 Filter

The Professional Choice for Massive Ponds and Heavy Bio-Loads

The OASE BioTec ScreenMatic2 39000 is the largest and most powerful flow-through filter in the ScreenMatic series. Engineered to handle the rigorous demands of large koi ponds and expansive water gardens, this system combines high-capacity mechanical pre-filtration with extensive biological treatment. Its centerpiece is an automated, self-cleaning debris screen that removes coarse waste before it can clog the filter foams, ensuring peak performance and significantly reduced maintenance.

This gravity-return system is designed for "above-ground" installation, allowing the cleaned water to flow back into your pond via a waterfall or discharge pipe. If you are managing a large-scale ecosystem with a high fish population, the BioTec 39000 offers the reliability and efficiency required for a healthy, balanced environment.

Key Features:

• Intelligent Self-Cleaning Screen: An advanced sensor monitors debris levels and automatically triggers the cleaning belt, depositing waste into a high-capacity removable tray.

• Massive Biological Surface Area: Features 18 high-performance filter foams in varying densities to provide an enormous habitat for beneficial nitrifying bacteria.

• Automated Maintenance: Minimizes the need for manual cleaning; the integrated handles allow you to clean the foams using pond water without ever removing them from the container.

• Double-Sealed Motor & Drive: Built with a reinforced screen and a double-sealed motor for maximum durability and a long service life in all weather conditions.

• Optimized Flow Management: Water is distributed evenly across the belt and foams, preventing "channeling" and maximizing contact time with biological media.

• PhosLess Media Tubes: Includes specialized filter media designed to bind phosphates, effectively starving algae of its primary food source.
