Silvent 931

SILVENT 931 is a small angled flat nozzle in stainless steel. The nozzle generates a wide thin air stream. Due to its small dimensions, the nozzle is very suitable for machine designs with limited space. The fact that the nozzle is blowing in 90° angle often makes installation easier. The SILVENT 931 is also commonly used in small, silent and efficient custom made air knifes. The Silvent technology makes it possible to combine efficient and silent blowing. SILVENT 931 fulfills the noise requirements of the EU Machine Directive as well as the OSHA safety regulations.
