Silvent 512

SILVENT 512: slot nozzle that generates a directed air jet. Suitable for all-purpose blowing and blowing in confined spaces. Compact size makes this nozzle a popular choice for use in machines and tools where clearance is limited. Combines advantages of low noise level and low air consumption with high blowing force. Meets OSHA safety regulations stipulating that air pressure in direct contact with skin must not exceed 210 kPa (30 psi). Also meets EU Machine Directive noise restrictions.
