Air Knife Ducting

Industrial Clamp-Connect Ducting for Air Knife Applications

An air knife, or airknife, is a system that uses bursts of air to do a job such as drying off cans on a canning line. These systems usually include a blower, duct or hose, and some sort of nozzle. On smaller systems, flex or plastic hose may be used, but on larger systems, hard ducting pipe is more likely.

Larger systems often utilize high pressure blowers and require hard ducting to accommodate the pressure where flex hose might balloon or wear prematurely.

US Tubing’s Clamp-Connect, airtight ducting offers a superior option, providing both a leak-free seal to maintain pressure throughout the system and a quick clamp connection for ease of adjustments and changes to any air knife system.

 

Benefits of US Tubing for Airknife Applications:
  • The ultimate seal for no-loss pressure applications
  • Fast clamp connections for ease of assembly

 

In addition, blower driven systems are often replacing compressed air systems because of lower ongoing operation costs and the ability to regulate pressure and flow particular to a given application. These systems often require a stronger, airtight ducting.

One of the most common industrial applications for air knives is the removal of moisture from parts after washing and prior to further processing, like coatings or painting. The reason that this application lends itself so well to the use of air knives comes from cost savings. Parts on overhead conveyors as part of a 3, 4, or 5 stage painting or powder coating system almost always uses either a gas or an infrared type oven between the final rinse and the actual painting. These heaters are of course very expensive to operate and, depending on how many shifts they are run on, can cost the company hundreds of thousands of dollars annually to power. By using air knife systems to blow off most of the water following the final rinse, companies are able to turn the temperatures in the oven way down, saving a great deal of money.

Us Tubing’s Clamp-Connect Ducting offers an airtight seal for these and more air knife applications to maintain optimal pressure and further improve the efficiency of the system.
