Air Jet Selection Guide

How Air Jets Work

Air Jets (Venturi nozzle) utilize the coanda effect (wall attachment of a high velocity fluid) to produce air motion in their surroundings. As illustrated on the right, a small amount of compressed air (black arrows) is throttled through an internal ring nozzle above sonic velocity. A vacuum is produced, pulling large volumes of surrounding, or “free” air, through the jet (blue arrows). Both the outlet and inlet can be ducted for remote positioning. If the end is blocked, flow simply reverses at well below OSHA dead ended pressure requirements.

The stainless steel air jets (Air Jets 6019SS) offer reliable and efficient blow-off and cleaning in corrosive, high temperature or washing environments. Thanks to the swivel fittings (9052), the air nozzles can be positioned precisely and dry the washed engine block quickly and efficiently.
