Introducing the MJ-GF Gyre Flow Pump Series
Superior Cross Flow Technology Explained
Comparing to traditional powerheads and wavemakers, based on propeller nozzle technology, our latest gyre generator is based on crossflow technology.
Propeller Nozzle Technology
• Dead spots with relatively poor water movement.• Very strong flow in the center,making coral placement very difficult.
• Very weak flow near the other end of the aquarium.
Cross Flow Technology
• Virtually no dead spots.• Evenly distributed flow rate throughout the entire aquarium.
• Water bounces back from the other side to create a full circulation.ie.generating "gyre flows".
Near-Silent Operation With Sine Wave Technology
Sine Wave Pattern
Electricity current alternates in a much smoother pendulum while using Sine Wave Technology
Traditional Pattern
Electricity current alternates in a very sharp pattern while using traditional Technology
All MJ-GF Series Gyre Flow Pumps Also Feature…
A Large Display Controller
Water Movement Mode
24 hours gyre flow cycle
