EXAIR's Back Blow Air Nozzles are engineered to clean inside of pipe, tube, hose or channel. An array of holes provide a forceful 360 degree air flow to clear out coolant, chips or debris created from machining processes. This nozzle prevents blowing chips further into a pipe or out the end, which could create a safety hazard. Since air flow is directed back toward the operator personal protective equipment is recommended. They deliver high performance suitable for a wide range of diameters from 1/4" (6.3mm) up to 16" (406mm)!

How the Back Blow Air Nozzle Works |
 |
|
Air Nozzles use the Coanda effect to amplify compressed airflow up to 25 times or more. Back Blow Air Nozzles eject air from an annular ring of nozzles on the outer perimeter, as illustrated. The ring of nozzles eject air, back toward the air inlet at an angle to form a cone of high velocity air. The airstream that results is a high volume, high velocity blast of air at minimal consumption. The air is ejected safely and cannot be blocked, maintaining OSHA's dead end pressure standard. |

Back Blow Air Nozzles are made from Type 316SS. -
A 1 NPT Back Blow Nozzle cleans out a hydrailic cylinder during repair and can clean out diameters up to 16". -
This M4 x 0.5 Back Blow Nozzle is just over 1/2 inch long and 0.2" in diameter in order to clean out holes a small as 1/4" in diameter.
