Air Knife Drying Systems and Components
Single-Stage and Dual-Stage Regenerative Blowers for Air Knife Systems
Operating Principles: The impeller rotates inside the blower housing, pulling air in through the inlet, or vacuum side. The impeller then accelerates the air or gas inside the housing until it is fully pressurized, and discharges it through the exhaust outlet, or pressure side.
Single-stage blowers are the most common type of Regenerative Blower; with these blowers, air travels around the internal air channel once and is then exhausted out to the application. Dual-stage Regenerative Blowers can provide a lot more pressure or vacuum than their single-stage counterparts because the airflow is channeled back around the impeller for a second rotation before being exhausted. This causes the air to be more laminar which greatly increases the velocity pressure of the conveyed air.
What about maintenance? The motor shaft is the only moving part, which spins the impeller directly; it does not come in contact with the housing at all and is, therefore, “wear-free”. Pre-lubricated bearings are the only wearing parts, and these days, bearings have some of the lowest failure rates of any mechanical item in existence.

Variety of Applications for Air Knife Systems
Atlantic Blowers offers custom-designed Air Knives for a wide host of applications. Whether it is for the food industry where sanitary materials are required or for drying clean products before a paint job, we work with each customer to offer a tailor-fit solution. Our team of experienced engineers will work with you to pair the best-suited blower for your specific air knife system. If you wish to send a sample of your product to test, we can set up a similar air knife system in our warehouse to verify the effectiveness, at no charge! If you would like help finding the appropriate system for a specific application, feel free to request an Air Knife Evaluation Guide and one of our team members will assist you with selecting all needed components.
Benefits of Air Knife Systems powered by Regenerative Blowers
For an Air Knife System powered by a standard 20 HP compressed air pump operating at 80 PSIG providing air to a 24†length air knife, the energy consumption of the pump alone is approximately $13,070 per year (not including maintenance). The same Air Knife System can be handled by our 5 HP Regenerative Blowers operating at 1.4 PSIG, which means the yearly energy consumption of the blower is approximately $3,267.48, a saving of almost $10,000. This means that one of our Air Knife Systems complete with a practically maintenance-free Regenerative Blower is 4 times cheaper than a system with a typical air compressor. This is just one of the many reasons why our blowers are superior for Air Knife Systems and many other applications.
Applications
Air Knife Drying / Air Knife Blowoff
An air knife system is meant to blow off any remaining substance (such as dust, water or any other liquid or debris) from products on a conveyor. These products have typically been washed or have been dipped in a liquid that needs to be dried for packaging. This is where an air agitation blower comes into play. As the product moves down the conveyor it passes through the airstream to be dried.
Food Processing
Regenerative Blowers can be used in the handling of delicate items, such as eggs in the food processing industry.
