The number of products we sell into the steel industry is large and the applications are diverse. However we do see some very common applications too. One of those is to use our Super Air Knife for a strip steel blow off.
One advantage of the Super Air Knife is that we can provide an unlimited width of continuous blow off for the widest of steel strips. The Super Air Knife produces an even air flow across the entire width, giving consistent results. A manifold of nozzles struggles to produce even and consistent air flow.
Another advantage is the space required for the Super Air Knife. The profile of a Super Air Knife is 1-3/4″ x 1.5″ . This is greatly smaller than any blower style knife or a manifold with nozzles. The Super Air Knife is also adjustable by using a simple pressure regulator on the inlet air supply. Adjusting the pressure will also affect the force and flow out of the knife.
Super Air Knives are available in aluminum, 303 stainless steel, and 316 stainless steel from out of STOCK in Cincinnati, OH. The stock lengths are up to 54″ long. This variety gives the customer more flexibility with the application. Whether we blow off the whole strip or only the edges, we have a length to fit.
I recently had a steel manufacturer with an edge blow off application. They were using 10 yellow plastic nozzles at 90 PSIG on each edge. The air consumption of these yellow nozzles was 290 SCFM at 90 PSIG. EXAIR provided an alternative Super Air Knife with a .003″ shim installed. This shim produces more force and flow than our stock .002″ shim. Even with the larger shim, and higher force and flow values, the EXAIR product saved more than 200 SCFM!
200 SCFM in an operation which is 24/7 and 365 days per year is equal to $26297.00, certainly worth the investment! And even for a 5 day a week, 250 working days per year, the new Super Air Knife solution can save $6000.00 per year! Not bad for a $325.00 investment.
Keep an eye out for these applications around your manufacturing facilities. EXAIR can help conserve compressed air and keep those operating costs down, so you can remain competitive.
