Multiple compartment internal filter for aquarium - has main compartment between inlet compartment and outlet compartment containing filter cartridge

摘要

The internal filter for the tank of an aquarium has an open topped rectangular body with a filter chamber between side chambers. One side of the chamber is a smaller chamber divided into two chambers by a partition across one corner. The smallest chamber has an inlet hole one side, also an inlet tube can be lowered into the other chamber. The height of the partition is lower than the remainder, forming an overflow weir. The flow then passes through an opening at the bottom and under the filter chamber, then through holes (3) in its base (2). The other side also forms a weir (17) communicating with another smaller chamber (7) containing a filter cartridge with a discharge tube through the middle.
