Description
Features:
- EXAIR's Back Blow Air Nozzle is engineered to clean the inside of a pipe, tube, hose, or channel.
- An array of holes provides a forceful 360-degree airflow to clear out coolant, chips, or debris created during machining processes.
- The nozzle prevents blowing chips further into a pipe or out the end, which could create a safety hazard.
- Since the airflow is directed back toward the operator, personal protective equipment is recommended.
- It delivers high performance suitable for a wide range of diameters from 1/4" (6.3 mm) up to 16" (406 mm).
- Type 316 Stainless Steel high temperatures, corrosive environments, and mechanical wear. Max temp 1000°F (538°C)
Applications:
- Part cleaning
- Chip removal
- Liquid blowoff
- Part cooling
- Material conveying
- Part ejection
- Fiber conveying
- Air assist
Advantages:
- Reduced compressed air cost
- 10 dBA average noise reduction
- Conserve compressed air
- Improved blowoff performance
- Compact
- Improved safety
- Meets OSHA noise level requirements
- Meets OSHA pressure requirements
- Improved production

How It Work:
- An Air Nozzle uses 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.
