Air Edger™ Flat Jet Nozzle

Model 47011 Air Edger™ Flat Jet is an extremely efficient flat jet air nozzle designed to provide a powerful stream of high velocity laminar flow and high force for blow off and cooling where air knives may not be enough.

When bench tested against several other flat jets, even those with special designed holes or shims, the Air Edger™ Flat Jet outperformed them all despite whatever claims others may make. Air consumption and noise levels are minimized with its special design and configuration.

The Nex Flow™ Air Edger™ Flat Jet is available with various size “gaps” all set by a flat shim. Three standard shim sizes are available - .004” (.10 mm), .008” (.2mm) and .020” (.51 mm). One, two or more shims can be “stacked” for a larger gap and greater force.

It is not always clear how tests and measurements are made by competitors and therefore validating claims can be difficult since such values depend on how tests are done. Therefore we measured a competitive unit under the same conditions as we measured our units. The flat jet of the competitor is of a similar type except that they are using a saw tooth shim design and different internal dimensions. We obtained the following readings when measured using the same parameters as for Nex Flow units.
25.1 SCFM - 15 oz force (Published figures were 22 SCFM and 22 Oz force)
The force/SCFM is a ratio of .54 as measured the same way as the Nex Flow Air Edger

One measure of efficiency is the ratio of Force/Air Consumption. The higher the ratio the better the efficiency.
If we compare to that of the Nex Flow Model 47011-4 the ratio is 12/20.5 = .58
And for the Model 47011-8 the ratio is 21/31.3 = .67
In both cases the efficiency of the Nex Flow units are higher in the comparative tests done. Under the same conditions

If you are not sure of which level of power you need, we recommend a Model 47211S Shim Set consisting of 2 - .004” shims, 2 - .008” shims and 1 - .020” shim and any two shims (or more) can be stacked to set the gap best suited to your application.


How Air Edger™ Flat Jet Nozzle Work

Compressed air enters the flat jet at the rear port at (A). Air is entrained at point (B) and (D) by the compressed air stream that leaves the flat jet from a small gap at the end. The entrained air follows the profile that directs the airflow in a perfect straight line to create a uniform sheet of air along the 2” length of the Air Edger™ Flat Jet Nozzle. The amplified air stream maximizes velocity and force to produce a well-defined sharp edge laminar flow with minimal wind shear for reduced energy use in blow off and cooling. Two screws at (C) allow you to vary the gap with a variety of sizes of shims (.004”, .008” or .020”). One or two shims may be used.
