Installation Notes of Air Knives

Installation considerations is a question many customers will ask. In order to make our customers more clear about our air knives’ installation, this article will introduce you the installation notes of air knvies.

The first one is our spider manifold air knife, which can be installed on the air distributor made by our company or your own company.It is mounted on the air distributor through these threaded ports. If there is extra air outlet, you can plug it with a choke plug and then screw it up. This is the installation of the spider manifold air knife. In addition, the installation of high-speed nozzle is the same.


Next, it is the installation of
 stainless steel air knife. It can be fixed by screw holes at both ends. Both ends of the air knife have a fixed screw at each end. Or you can remove the screws directly, use round steel or round rods, and solder them up for fixing. Different lengths, according to their own needs to transform.

So, how is our 
air knife installed? For example, here is the air inlet, and the other side is the screw. Then we can use this installation baffle matched with our Coanda air knife to fix it.Screws are used to hold it in place.

Then, the installation profile with a circle is installed at our air inlet to fix it. One is 76mm and the other is 63mm.It is installed at our air inlet, which can adjust the Angle of our air knife. Then, for this rectangular hole, we can adjust the height of the air knife by sliding screws, which is very convenient.

Next is
 super air knife. Each of our super air knives, the standard one, will have four M6 screw holes on its back. Then our customers can laser with stainless steel, make two L-shaped baffles for fixing or directly support them, and install them on it,it is ok. In addition, if the air inlet is at one end, it affects your installation, you can change the air inlet to the side or top. This can be changed according to the installation site.

Similarly, our 
air wipe also has 4 M6 fixed screw holes on its back.We use screws to firmly fix the air wipe for installation.These are some of the considerations for the air knife when installing.

In addition, when some of our customers installed the air knife on their equipment, we sometimes received some feedback from them, such as why the air knife is very noisy. Why is this? In general, this situation is caused by two factors. 


The first one is that when you blow dry the irregular product, when the high-speed airflow blows on the surface of the product, a lot of whistles will be generated. There is no way to avoid this sound, so we can only do a sound insulation treatment on the surface of our equipment.

So how should we change?The air knife should be installed in a slanted way to avoid being parallel to the iron bar. Let me give you an example. If the effective length of our conveyor belt is 500mm, then our air knife should be longer. Because of the non-horizontal installation way, the required air knife length is longer. We can use a length of 550mm or 600mm to effectively avoid this noise.


Another advantage of this type of installation is that when we are blowing a stepped product, the air knife can effectively blow water from one corner to another, and then blow it out. This is a very good result, but many customers often ignore this when installing.
Then the second situation is that the method of installing the air knife is wrong. Where is wrong? For example, your conveyor belt is passable.and then, your product is relatively heavy, in addition to the conveyor belt mesh, there is a piece of iron bar.So, in this case, if you set your blade horizontally to the iron bar, the conveyor belt will produce a loud whistling sound as the iron bar passes over the blade during transmission. This is due to improper installation.

Admittedly, all the selection and installation of air knives, we will provide professional advice and guidance to our customers to ensure that our products can achieve the maximum blow-drying effect on customers’ equipment.

After learnning about the installation precautions of our air knives, if you have any questions, please feel free to contact us. We will provide CAD or 3D drawings to support your design and help you solve every drying problem.
