Airknives And Side Channel Blowers – Working Together
Airtec designed a bespoke airknife drying tunnel which comprised a combination of high velocity airknives and miniature bespoke air cannons.
A side channel blower was employed for this particular application as these can be the most cost effective solution for airknife applications with a relatively small outlet surface area.
The bespoke airknives within the tunnel were calculated to give a sufficiently high exit air velocity, whilst creating back pressure to generate heat. The relatively high pressure capability of the side channel blower can be utilised in this way to further enhance the drying performance of the system, without the use of additional process air heaters.
