RK2 AC Series Foam Fractionators

Meet the newest models of RK2’s commercial foam fractionator lineup! Our AC series is designed for low flow rate applications while keeping the performance and quality that larger RK2 models have become known for. RK2’s nearly 30 years of engineering experience combined with the extensive R&D we are proud to offer a truly commercial grade foam fractionator for aquarium professionals, home hobbyists and aquaculture professionals alike. These units are built to withstand the most demanding applications. We utilize a design that is based on proven science and volume metrics to bring you the best performing fractionators available today.

Design

All RK2 fractionators utilize counter current design. This means incoming (dirty) water enters high on the reaction chamber or vessel. The incoming water then travels downward through the rising air, which is injected low inside the reaction chamber, before exiting the bottom of the reaction chamber. In comparison, a co-current designed model has it’s incoming water and air/water mixture entering at the same level inside the foam fractionator. Once inside the fractionator, both the incoming water and air/water mixture travel in the same direction, which offers little to no mixing and operates with a much shorter contact/dwell time.

Materials

The AC series is made from the highest quality materials available. Our molded bases are made from High Density Polyethylene (HDPE) that doesn’t require gluing or bonding to fabricate. The reaction chamber is made from a single section of acrylic tube. The riser cone, collection cup, and collection cup lid are made from nearly non-breakable polycarbonate material and our Mazzei Air Injector (Venturi model only) is made from highly durable ozone resistant Kynar. This guarantees it will not break down when exposed to ozone.

Efficiency

When coupled with the recommended L1/L2 Vectra pumps, our foam fractionators operate at approximately 1amp of power at 12VAC. Simply put, there is no reason to look anywhere else for your foam fractionator needs! Whether you are a hobbyist in need of a fractionator for your larger display tanks or an industry professional in the aquaculture or public exhibit sectors, the AC series fractionator by RK2 is your answer!
