Each size can produce a number of flow rates, as determined by a small internal part called a generator. If Btu/hr. (Watts) requirements, or flow and temperature requirements are known, simply select the appropriate vortex tube according to the specification information shown below or the performance tables shown on the following page. Keep in mind that the vortex generators are interchangeable. If, for example, a Model 3215 Vortex Tube does not provide sufficient cooling, you need only change generators within the vortex tube to upgrade the flow rate from 15 to 25, 30 or 40 SCFM (425 to 708, 850 or 1,133 SLPM). Generator part numbers are shown in the “Accessories” listing on page 206. Vortex Tube Specifications 32XX series Vortex Tubes optimize temperature drop and airflow to produce maximum cooling power or Btu/ hr. (Watts). Specify 32XX series Vortex Tubes for most general cooling applications. 34XX series Vortex Tubes provide lowest cold air temperatures, but at low cold airflow (when less than a 50% cold fraction is used). Specify 34XX series Vortex Tubes only where temperatures below 0°F (-18°C) are desired.
