10. SUB-COMPONENT DOCUMENTATION
This section contains sub-component manufacturers information and supporting documentation that may be of use to
operators.
10.1 Compressed Air Line Sizes
Compressed air lines should be sized to hold pressure drops to a minimum. So not used restrictive fittings such as quick
connects. They can “starve” the Vortex Tube by causing line pressure drop. The following chart gives suggested line sizes
for pipe and hose.
Line Sizes for Runs Up To:
10 FT
(3 M)
10 - 50 FT
(3 - 15 M)
50 - 100 FT

10.1.1 Compressed Air Supply
For best performance, use line pressure 80 to 100 PSIG (5.5 – 6.9 BAR). Vortex Tubes are rated in SCFM (SLPM) at 100
PSIG (6.9 BAR) supply pressure.
With proper filtration and separation for dirt, moisture and oil from the compressed air supply, the Vortex Tube will run for
years with no maintenance required. Use a 25 micron or smaller filter separator that is sized to SCFM (SLPM) rating of the
Vortex Tube.
To prevent problems associated with oil, use an appropriate Oil Removal Filter for Vortex Tubes up to 30 SCFM (850
SLPM) . The oil removal filter should be used downstream from the automatic drain filter separator. Filter should be used
within 10 to 15 ft ( 3 to 4.6 m ) of each Vortex Tube.
For Replacement or Repair filter and regulator parts contact Yokogawa.
10.1.2 Setting the Vortex Tube
Hot and cold temperatures produced by a Vortex Tube are infinitely variable by adjusting the slotted valve at the hot air
exhaust. Opening the valve reduces the cold airflow and the cold air temperature, Closing the valve increases the cold
airflow and the cold air temperature.
Set the Vortex Tube with a thermometer. To measure temperature accurately, it should be inserted into the cold muffler or
a piece of tubing on the cold end exhaust.
10.1.3 Troubleshooting & Maintenance
If the Vortex Tubes Does Not perform properly, check for these common problems:
1.) Loosed Cold Cap or Cold Muffler- A loosed cold cap or cold muffler will cause poor performance. Make sure it is tight.
2.) Inlet Pressure- Low inlet pressure supply will cause poor performance. Measure the pressure at the compress air
