Air Nozzle Selection Guide

Selecting the Right Air Nozzle

EXAIR manufactures a wide selection of Air Nozzles and Jets, which are divided into two groups. The first group includes Air Nozzles and Jets that deliver force up to 22 ounces (624 grams), making them suitable for most blowoff, drying and cooling applications. The second group includes Air Nozzles that produce high force up to 23 pounds (10.43 kg) where additional reach and force are required.

• Brass general purpose applications. Max temp 400^oF (204^oC)
• Zinc aluminum alloy general purpose applications. Max temp 250^oF (121^oC)
• Type 303 Stainless Steel high temperatures and corrosive environments. Max temp 800^oF (426^oC)
• Type 316 Stainless Steel high temperatures, corrosive environments, and mechanical wear. Max temp 1000^oF (538^oC)
• PEEK replaces metals in harsh environments. Offers chemical resistance, non-marring. Max temp 320^oF (160^oC)

Air Nozzles use the coanda effect to amplify compressed airflow 25 times or more. As illustrated on the right, compressed air (black arrows) is ejected through a series of nozzles on the outer perimeter. As the air travels along the outer wall of the nozzle, surrounding air (blue arrows) is entrained into the stream. The airstream that results is a high volume, high velocity blast of air at minimal consumption. The air is always ejected so it can vent safely, well below OSHA dead ended pressure requirements, should the nozzle end be blocked.

Adding Flexibility

For applications where frequent repositioning of the standard force Air Nozzles and Jets is required, the Flexible Stay Set Hoses^TM are ideal. Simply mount the hose in close proximity to the application and bend it to aim the airstream at the target. Since the hos has “memory”, it will not creep or bend. It always keeps the aim until physically moved to the next position.
