The mini multi-channel round jet nozzles of the 600.388 series generate a point of concentrated air even at large distances. The compact design of this series makes the nozzles particularly suitable for use in locations that are difficult to reach. The special design at the nozzle outlet prevents air penetration into human skin. These nozzles comply with the OSHA standards.
