Stainless Steel Adjustable Air Amplifiers Replace Blower in Exhaust Hood Application

Vent hood

EXAIR Stainless Steel Adjustable Air Amplifiers model 6034

 

I was working with our Indonesian distributor the other day on an interesting application in the sugar refining industry.

The application was in a sugar refining plant. As the sugar cane is cooked down, the resulting gas vapor is pulled up through a vent hood and exhausted outside the building. The customer was using a 16” diameter blower to create the needed draft to draw the vapors. The problem is that the vapors are corrosive and sticky when cold. The effect is that the blower blade becomes caked with deposits which, in turn corrode the blade and it must either be cleaned and/or replaced at frequent and regular intervals.

The customer wanted to get away from having to deal with the blower issue if they can, so they turned to our distributor for ideas on how to solve the problem using EXAIR equipment. Turns out that a cluster of (3) model 6034 4” Adjustable Air Amplifiers operating at 5 BARG input pressure are able to generate the necessary flow to replace the blower in this system.

The keys to success in the application were the fact that the Adjustable Air Amplifiers are constructed of Stainless Steel to resist the corrosive effects of the gas vapor. Also, there isn’t any deposits on the blade that need to be dealt with. While cleaning of the Air Amplifiers is recommended in this application, the maintenance interval was able to be much longer between cleanings.

In many industrial applications, blower driven or electric motor driven equipment is usually preferred in an effort to save energy. This was a good example of a case where the quality of having no moving parts was able to offset other maintenance costs that made use of a blower actually more expensive for the user.
