Silvent 394W-S Air Knife

SILVENT 392 W-S – 396 W-S: is an energy-efficient, stainless steel air knife that generates an extremely strong, effective blowing force while keeping the sound level exceptionally low. This air knife makes the best use of compressed air and its unique design introduces an entirely new quality to blowing technology. The effect is achieved through the aerodynamic nozzle which maximizes co-ejection while every hole profile is also designed to achieve as great a surrounding jet area as possible.
