A simple solution to excessive
air consumption and noise level on compressed air "blowoff"
operations. Using a small amount of compressed air as a power source,
Air Jets and Nozzles produce outlet flows up to 25 times compressed
air consumption. Air savings, compared to open copper tubes or pipe
nipples commonly used for blowoff can be as high as 80%. Less compressed
air means less noise – typical noise level reduction is 10 dBA.
All Air Jets and Nozzles meet OSHA maximum dead-ended pressure requirements.
An open 1/4" (6mm)
copper tube, by contrast, ejects pure compressed air at up to 40
standard cubic feet per minute (1133 SLPM), the entire output of
a 10 horsepower compressor. Annual energy cost can exceed $1,000
per year. Noise levels in excess of 100 dBA are commonly produced.
When supply pressure exceeds 30 PSIG (2 BAR), an open jet violates
OSHA static pressure requirements.

| How
Air Jets and Nozzles Work |
| Air Jets utilize
the coanda effect (wall attachment of a high velocity fluid) to produce
air motion in their surroundings. As illustrated at bottom right,
a small amount of compressed air 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. |
Air Jets produce
the highest force to air consumption ratio of all EXAIR blowoff products,
making them the most economical choice for "tough" applications
such as part ejection or chip removal. Both the outlet and inlet can
be ducted for remote positioning. If the end is blocked, flow simply
reverses at well below OSHA static pressure requirements. |

Nozzles also use the coanda effect to amplify compressed airflow 25
times or more. As illustrated to the right, compressed air is ejected
through a thin ring nozzle. As this ring of air travels along the
outer wall of the nozzle, surrounding air is entrained into the stream.
This entrained airstream combines with the air ejected from the center
hole to produce a high volume, high velocity blast of air – at minimal
consumption. The slotted end allows air to vent safely should the
nozzle end be blocked.
Both Air Jets and Nozzles are easily
retrofitted to existing blowoffs, and are available in adjustable
or non-adjustable versions.
