MRC® iSeries Fractionator™
The pinnacle of foam fractionation design and technology, MRC® has once again redefined the protein skimmer. Created for public aquariums and aquaculture facilities, discerning aquarists quickly began implementing them into their large home systems. With numerous different sizes and flow rates available, nothing else comes close.
Technology
Equipped with the most advanced fractionation technologies pioneered by MRC®.
Exclusive to MRC® iSeries Fracitonators, the industrial needle-wheel tech produces more foam using less power than any other competing product.
Capacity
From commercial aquaculture facilities to major public aquarium displays, iSeries™ Fracitonators are available for any sized system.
Precision
The iSeries™ Fracitonator is the only industrial protein skimmer designed from the ground up; employing MRC’s needle-wheel technology and fabricated within the highest tolerances. We like things to be right and right the first time around.
Detail
Our team will work with you to ensure every need and desire is addressed. System dynamics will be assessed before model selection giving you the best product for your specific application. As always, 100% American made.
Triple-Cone Washdown
No more manually cleaning the collection cup. MRC’s triple-cone system sprays three distinct cones of water, targeting inside the riser neck, the collection cup walls, and the area in between. With no moving parts or large clunky wipers to interrupt the foam head, you not only don’t have to worry about a malfunction, but you don’t have to clean the cleaner!
Heavy duty HDPE body
All iSeries Fractionators are fabricated out of heavy gauge HDPE. Extrusion welded in house to maximum durability and quality control. Indoor and outdoor safe; UV stable and ozone compatible


Dedicated Ozone injection port
A dedicated ozone port gives you the ultimate control over your ozone dosing. Adjustments here do not affect your fractionation air draw whatsoever, unlike with competing models, putting more control in your hands.
Industrial Needle-wheel Tech
Pioneered by MRC®, it is the most advanced fractionation technology available today. It produces the finest quality bubble in the thickest density possible, resulting in substantially more surface area to attract and remove contaminants. All this at a fraction of the power draw. Exclusive to MRC, available only in iSeries fractionators.
Customizable
The only industrial fractionator that’s customizable. We’re happy to change the height, footprint, and inlet/outlet sizes and heights. We’ll even change the locations of the plumbing for those instances where you have to squeeze the unit into an existing space.
High-quality valves
All iSeries Fractionators are equipped with Asahi Butterfly & ball valves, regarded as the best available. We use spears plumbing for everything else, leaving no room for upgrades. Prefer a different brand valve? No problem at all; we’re happy to customize that for you.


Screw top lid
Easily access the collection cup with our screw top lid. Just a few turns and you have complete access inside for manual cleaning.
