The surface flow to the bottom flow is from up to down the figure, respectively.
All of the CONN Blades[R] provide superior pumping action for better material circulation and top to bottom flow. Our IT style is a high pumping/low shear blending blade and our ITC style is an 8 vane open style blade providing more shear than the IT but is not as aggressive as the ITT.

The continual bottom flow provides an effective ventilation system, drawing in new oceanic water and expelling brackish water.
This compact system mixes metered seeding products with an air stream while eliminating potential manifold air leaks.The design eliminates the need to remove a heavy component when calibrating the metering system and reduces the time for changeover from top to bottom flow. This new function allows users to switch seeding products without difficulty by using a slide that can be locked to ensure accurate product placement.
However, while lowering the feed tray the problem becomes harder to solve with the given reflux ratio and bottom flow rate specifications.
