Poolking produces main aquarium equipment such as Foam Fractionators. This product can also be applied to seawater or freshwater aquariums. Their process capacity is 7.5m ³/ H to 400m ³/ h. The design retention time is more than 2 minutes. The foam fractionator designs of freshwater can induce a constant flow rate above and below the airflow through the Venturi tube, and enable the foam fractionators produce bubble curtain of about 11% volume over the entire surface area.

The foam fractionator is not only energy-saving and environmentally friendly, but also has low equipment energy consumption. The bubbles are rich and delicate, which can increase dissolved oxygen in water and remove suspended solids in water. Moreover, it can effectively remove organic substances such as residual bait, feces, and colloidal substances from water, and ensure water quality safety.
