Description
The RK75PE‑HF is a high-flow saltwater PE (polyethylene) protein fractionator designed for high-bioload, large-scale marine systems. This advanced foam fractionator efficiently removes dissolved organics, proteins, and fine particulates while increasing oxygenation and reducing microbial load.
Key Features
-
Counter-current foam fractionation: water enters from the top and air (or ozone) is injected at the base via a venturi injector.
-
One-piece, rotationally molded PE reaction chamber for maximum durability and leak resistance.
-
Integrated internal and external rinse system to prevent salt buildup and maintain skimmer performance.
-
Clear sight gauge for monitoring liquid and foam levels.
-
Screw-top lid for easy maintenance and access.
-
Industrial-grade Hayward or Asahi ball valves for reliable flow control.
-
Compatible with ozone systems through a dedicated injection port.
-
Includes a dedicated venturi pump for air/ozone draw.

Benefits
-
Greatly improves water clarity by removing dissolved organic waste
-
Boosts dissolved oxygen levels in the water
-
Reduces bacteria and pathogens through foam export
-
Supports high stocking densities in aquaculture and marine holding systems
-
Built for continuous, heavy-duty operation
Applications
-
Commercial marine aquaculture (recirculating systems)
-
Public aquariums and marine exhibits
-
Large reef or fish-only systems
-
Quarantine and broodstock facilities
-
Research and laboratory-based marine systems
Installation & Maintenance
-
Needs a feed pump and a venturi pump for air/ozone injection
-
Must be mounted on a sturdy base that supports its full weight when operational
-
Requires plumbing for inlet, outlet, rinse, and foam waste
-
If using ozone, connect your ozone generator to the venturi port
-
Regular maintenance: clean rinse nozzles, discard waste foam, check seals and O-rings, inspect venturi and valves
Why Choose the RK75PE‑HF?
