Will Darmani bins work with full floor aeration?

Yes, Darmani flat bottom bin models will work with any style of aeration.

Note: If a full floor aeration systems is used, then one should use concrete base and make sure they have a good sub-base.

Why does Darmani cross-flow have better aeration results than full floor aeration?

Air flow is all about reducing static pressure and maximizing airflow through minimizing restrictions. The Cross Air is suspended over 5′ off the floor thus reducing static pressure considerably. The Cross Air has NO restrictions as it is open on the bottom and reaches efficiently to all the cross style reaches all sides of the bin.

Why are so many customers considering a different aeration system other than a traditional full floor aeration?

Simply, three reasons.

  1. Cost
  2. Air Flow
  3. Easy Cleanup

Full floor aeration systems usually come standard with some sort of unload system which can make some bin models more expensive than hopper bins. What dealers forget to tell customers about full aeration systems is the fact that the full floor aeration is susceptible to fines. These fines may build up over time, thus blocking air flow which may restrict all air flow so that no air movement takes place. Its only usually a matter of time as to when this will occur and when it does, the customer has to take apart the entire floor, clean everything and then re-assemble back ensuring no gaps etc. This involves a lot of manual labor.

What is static pressure and how is it reduced?

Static pressure is the resistance to flow (energy added by the fan) measured in inches of water gauge.

What makes an effective aeration system?

Quite simply, the system that both reduces the static pressure and has the least amount of restriction to allow maximum air flow.
