Air knives from Nex Flow dramatically reduce compressed air and noise
levels as compared to other blow-off
products. Air knives provide a
compact, and efficient means to
dry, clean and cool materials.
Air knives operate by entraining
the surrounding air along with
the compressed air utilizing the
coanda effect essentially
converting energy which would
normally be lost as noise and
pressure drop into useful flow.
No matter what anyone tells you,
all air knives using the coanda
effect are essentially the same
in performance with negligible
differences. However, how they
are made is what is very important
to make sure you get value for
Nex Flow Air-Blade
Air Knives are superior to competitive
units for the following reasons:
All our air knives are full flow which means they can be put end to end for continuous flow and takes up less space in tight areas. Even one competitors so-called full-flow standard answer to our Nex Flow standard air blade air knife is not nearly as efficient as ours by their own published values and is only a small, flimsy version in comparison.
All our air knives come with a stainless steel shim to maintain the gap for the compressed air to exit. Many companies use plastic shims which may be squeezed for uneven flow but more important, no matter how clean you make the compressed air line, the plastic will wear. Plastic shims is one of the biggest complaints customers have with air knives Nex Flow however uses stainless steel shims as a standard in all air knives.
Easy mounting. Some air knife designs are difficult to mount requiring them to be taken apart, often effecting flow and making the job of mounting more difficult. All Nex Flow air knives have convenient mounting holes.
All Nex Flow aluminum air knives are anodized while many competitors do virtually nothing to the aluminum for protection. In fact, if you want any better protection they try to get you to by more costly stainless steel when simple anodizing is less costly and already standard with Nex Flow.
Flexibility in connections. Except for the very short lengths, both standard and X-stream versions have compressed air ports at the ends and the back for flexible choice in air input.
