Even without additional accessories, the Super Air Knife is the right choice for many compressed air applications. But when it comes to process optimisation, sometimes more is needed. It can then be advisable to regulate the position, force or flow rate. In this post, we present optional accessories for this purpose.
One important requirement first: to achieve the desired results with the Super Air Knife, the correct diameter of the compressed air supply line is essential. It must have a certain minimum size so that the best possible flow rate is achieved at a given pressure. The following table shows which pipe diameters are required depending on the model and line length.
Shim sets
Pressure regulator / filter regulator unit
Universal mounting system
Electronic Flow Control
Shims can be used to control the compressed air output from the air knife. To meet the individual needs of different users, they are available in various sizes. Firstly, there are the red shim sets with a thickness of 0.05 mm. For a thinner option, we offer the amber 0.025 mm size. If a thicker shim is required, we also stock the 0.076 mm size. The 0.1016 mm size is available as well.
A key advantage of our shims is that they can be combined. For example, this allows an air gap of 0.203 mm to be created. Thicker shims widen the air gap, which increases blowing force and air velocity. However, air consumption and noise level also increase.
The optimum pressure to set your system to is the level at which your production can run efficiently and without waste. You may have 6 to 7 bar available, but only need 3 bar for your air knife to do the job. Reducing the pressure can save a lot of money in the long run.
With its three matched filtration stages, the EPUTEC filter regulator unit with pressure regulator delivers consistently clean, dry compressed air. This high air quality ensures a long service life and high performance from our compressed air products.
The universal air knife mounting system is a quick and easy way to position the air knife precisely and achieve optimum performance in your application. For air knives under 24 inches, one mounting kit is sufficient. Two are needed for sizes between 25 and 54 inches, three for sizes between 55 and 71 inches, four for sizes between 72 and 95 inches, and from 96 inches five mounting systems are required to support the weight of the air knife.
For food applications, special screws and seals are available for the mount that prevent food residues from building up in the screw recesses.
The Electronic Flow Control (EFC) limits compressed air consumption by shutting off the air flow as soon as there is no longer an object in the detection range.
An integrated photoelectric sensor and timer ensure that this happens precisely. Controlling compressed air consumption in this targeted way can noticeably improve the energy efficiency of an application.
