When compressed air escapes, it sizzles.
The noise can be as high as 100 dB and can damage the hearing.
The trade association has enacted stringent regulations regarding this matter. One more reason to use a silent air nozzle.
Depending on the pressure, the sound of the SO-NW4 can be reduced down to 20 dB without any loss in pressure. A special air duct utilizes the pressure more effectively.
The nozzle can be regulated with the screw adjustment at the rear, saving the cost for the throttle valve.
To curb the noise created by the escaping compressed air the air jet is directed through
5 output holes - resulting in reduced noise.
The regulator nozzle SO-RD is used for liquid products. The fluid quantity can be adjusted or even be shut off by turning the SO-RD.
