OASE BioMaster² Thermo 350 AU (94688)

The OASE BioMaster² Thermo 350 AU (94688) is a premium external canister filter designed for aquariums up to 350 litres. Combining powerful mechanical and biological filtration with an integrated 200W HeatUp heater, this all-in-one filtration system keeps aquarium equipment out of sight while delivering crystal-clear water and stable water temperatures.

Featuring OASE's innovative EasyClean Pre-Filter Module, routine maintenance is faster and easier than ever. Simply remove, rinse, and replace the pre-filter without opening the main canister, reducing maintenance time while extending the life of the biological filter media.

The BioMaster² Thermo 350 utilises a large 5.6-litre filter volume with Hel-X biological media and filter sponges to provide exceptional mechanical and biological filtration. An improved water flow design delivers up to 1,100L/h, while the energy-efficient motor operates quietly for reliable, long-term performance. The integrated priming button and safety shut-off valve make installation and maintenance simple and mess-free.
