NCA Crossflow Airshield

 

NCA Crossflow Airshield

Airborne contaminantes generated by high power laser processing applications can be diverted with Haas LTI's NCA Crossflow Airshield.

Using small quantities of compressed air, a pneumatic low-pressure zone is generated near the optical path of the high power beam, creating the transverse flow of very large volumes of ambient air to divert airborne particulate matter traveling longitudinal to the beam. Contaminating particles that might impinge on the optical surface are deflected away.

The NCA Crossflow Airshield is adaptable to the Haas LTI welding or cutting nozzle and also the focus module for a complete beam delivery system. Prices for complete beam delivery systems are available upon request.

How It Works

NCA Crossflow Airshield, NCA Series

The NCA Crossflow Airshield works through the artificial creation of a low-pressure area in a venturi. Compressed air or gas, at approximately 15 PSI, is passed through a small aperture that produces an annular shaped column of air that follows the side walls of the venturi. This produces a low pressure area in the center of the venturi, which draws in large volumes of outside air that pass through the laser beam path.

The flowing air diverts particulate matter away from the optics and through the exhaust.


Dimensions for Large Model

Length x width x height Optical Aperture  
5.3" x 2.8" x 2.0" 30mm Minimum 15 PSI Required
     

Dimensions for Small Model

Length x width x height Optical Aperture  
3.3" x 1.8" x 1.3" 15mm Minimum 10 PSI Required
     

All models work with either compressed air or any selected gas for purging contaminating particles from the laser beam path.
