Description
AIRMASTERS Air knife for powerful blowing!
The AIRMASTERS air knife has been developed to perfection in its aerodynamic design. The air knife produces an efficient, uniform and spatula-like blow, which creates a pneumatic scraping effect without mechanical contact.
The AIRMASTERS air knife has the highest possible flow amplification factor and is extremely quiet.
All AIRMASTERS air knives utilize the “Coanda” effect, which allows outside air to be added to the air flow in addition to the compressed air. This results in efficient and quiet blowing with minimal compressed air consumption. AIRMASTERS air knives use only 30% of the compressed air compared to open pipes or air deflectors.

Compressed Air or Blowers?
For an appropriate blow off in cleaning or drying, the choice for using a blower system over a compressed air is not always so clear cut. It is not just energy use as a great deal of other factors also impact the decision. There is also built in bias from both compressed air system providers and blower system providers so this must be accounted for in evaluating which would be the best choice.
Salesmen’s talk
Blower sellers tend to compare the best aspects of a blower system in a best case scenario to the worst case scenario for compressed air, usually focusing entirely on energy cost to the exception of other factors, and even the actual pressure levels that need to be used in the application. Compressed air blow of providers tend to overstate the negative aspects of blowers, worst case for maintenance and noise, shutdown costs, and stretching the real limited shear force, such systems can obtain. Since most of all compressed air that is produced today (up to 70%) is still used for blow off applications, clearly there is a reason for using compressed air in many cases.
Which is the best system?
Several factors should be carefully considered for any blow-off application in choosing the best system. Each factor may have a greater or lesser weight over the other depending on the particular situation. They are as follows…
