757-L
SILVENT 757-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 7 times that of an ordinary air blow gun. Despite the high blowing force, both the noise level and air consumption are low. This air blow gun is frequently used in the glass industry, paper mills, foundries, steel mills etc.
