SILVENT 9002W-S: an energy-efficient flat stainless steel nozzle that generates a strong, efficient blowing force at an exceptionally low noise level. Compressed air is optimally used in this flat nozzle, which through its unique design introduces a completely new blowing technology feature. The aerodynamic nozzle design achieves the effect by maximizing entrainment of air. Each orifice is also uniquely designed to optimize the entrainment area. These small orifices combined with the aerodynamic slots of the nozzle provide high efficiency.
