SILVENT 804: an energy-efficient Laval nozzle that is part of Silvent’s new “SILVENT SOFT™” series. The air nozzle is specially made in EPDM rubber to minimize the risk of scratches, such as on the surface of tools. The product meets the unique combination of demands for a scratch-free surface and high blowing force by applying Silvent’s patented Laval technology. Silvent Laval technology is achieved by surrounding a core of air traveling at supersonic speed with a protective sheath of air moving parallel to the central air jet. The SILVENT SOFT 804 is ideal for all industries in which equipment and products are handled that cannot be damaged during compressed air blowing.
