• SIlvent air knifes

    The Silvent Technology reduces turbulence and creates a more uniform, even, and straight air stream when blowing with compressed air. Also called a laminar air stream.

Silvent 755-L High Force Safety Air Guns

SILVENT 755-L: with a stainless steel Laval nozzle. A core stream traveling at supersonic speed surrounded by a protective sheath of air moving parallel to the central jet makes optimal use of your compressed air. Around the Laval orifice there are divergent slots that generate a quiet, powerful and laminar air stream. The blowing force is approximately 5 times that of an ordinary air gun. Despite the high blowing force, both the noise level and air consumption are low. This safety air gun is frequently used in the glass industry, paper mills, foundries, steel mills etc.
