BIOTEC 12/18/36 SCREENMATIC FILTERS mechanical and biological, multi-chamber, flow through filters.

Oase have once again set new standards for outstanding filtration with simple operation and fast, easy cleaning. The specially designed SCREENMATIC SIEVE retains all debris particles above 300 microns, the then lightly polluted water flows through special matting where it is enriched with oxygen. The water then flows through different grades of filter foams where mechanical and biological cleaning takes place. The final 'individual' chamber is so-called because you have the choice of changing the standard Zeolite media for an alternative such as Phosless , an activated carbon that removes phosphates and reduces algae (particularly useful during hot summer months). All Oase Biotec filters accept direct connection of Bitron Ultraviolet Clarifiers.

BIOTEC SCREENMATIC - Oase engineers have designed a motor driven, rotating 300 micron screen sieve, with a timed rotation cycle every 30 minutes. This effectively removes large solids such as leaves and twigs before they enter the filter media. These large solids are deposited in a debris container for easy disposal. Removal of this course debris, before it reaches the Filter Foams, significantly improves the performance of these filters with efficient decomposition of nutrients thereby reducing the maintenance requirement.
