This is a question that we are sometimes asked by clients who look at our complete Air Nozzle range and see that we have everything from the tiniest M4 nozzle up to some really large ones that fit a 1-1/4” steel pipe. So, what would you use model 1114SS for anyway?
I just so happen to have a perfect scenario for you as described below.
A recent customer inquired with me about some method to blow off large diameter electrode holders for a furnace application. For those of you who do not know, furnaces used to smelt aluminum, zinc, steel and other alloys tend to be very hot and dirty places.
Being as such, a lot of debris tends to collect on horizontal surfaces including those of the electrode holders themselves.
What happens is dirt and dust are building up on the top of the holder and when it is opened it is becoming trapped between the holder and electrode causing arcing to go on inside the holder. The environment the solution will need to work in runs about 1500 – 1600°F. The area immediately around these holders is even hotter. So any nozzle placed in that environment will need to be able to withstand that temperature.
The solution: (3) model 1114SS (1 NPT Stainless Steel Super Air Nozzles) are placed in a triangular configuration to blow all the debris off of the top surface of the holder and electrode prior to opening to completely eliminate the arcing problem that had been occurring.
The key to the solution was to have an effective force generating nozzle that could project maximum force at distances well over 2 meters from a target and do so in a very hot application.
So, now you have one very good idea of how and where the larger Stainless Steel Super Air Nozzles can be used.
