Newly released, the EXAIR High Velocity Air Jet and Adjustable Air Jet are now available in Type 303 Stainless Steel, providing greater durability, corrosion resistance and a higher maximum temperature rating of 400 °F. Type 303 stainless steel has good resistance to mildly corrosive atmospheres along with good oxidation resistance at elevated temperatures, making the stainless steel Air Jet a great choice for blowoff or part drying in your harsh environment. Both types of Air Jets are also available in brass, for applications at 275°F and below, and when corrosion resistance is not as critical.
Air Jets utilize the Coanda Effect – wall attachment of a high velocity fluid – to produce air motion in their surroundings. As illustrated above, a small amount of compressed air to the inlet (large black arrow) is throttled through an internal ring nozzle above sonic velocity. A vacuum is produced, resulting in large volumes of surrounding, or “free” air, being pulled in through the jet (blue arrows.)
How Air Jets Work
Both the outlet and inlet can be ducted for remote positioning applications.
If the end is blocked, flow simply reverses at well below OSHA dead end pressure requirements, ensuring safe operation.
The High Velocity Air Jet comes standard with an .015″ shim, and a Shim Set is offered that includes .006″ and .009″ shims to provide additional adjustability and control. The Adjustable Air Jet has a variable gap design, and can be adjusted and locked to meet the required airflow and thrust parameters.
When you are needing a simple solution to reduce excessive air consumption and noise levels on compressed air blowoff operations, EXAIR has a large line of Air Nozzles and Jets to solve your problems. You can contact an Application Engineer to discuss which Air Jet or Nozzle to best fit your application.
