The Meech Stainless Steel Vortex Tubes are known for being able to convert compressed air into two airflows (a hot, and an extremely cold one). In addition to this, the compressed air can enter the spin chamber tangentially, leading to the column of air placed inside the tube to rotate at speeds that are up to 1 million rpm. The air located outside the column can move very fast and deliver a lot of energy. On the other hand, the air at the center of the column is moving relatively slowly and have little energy.
The hot outer air is bled off at one of the tube's ends, at the same time, while the Vortex tubes come with no moving parts producing temperatures that can be as low as 50 degrees Celsius and can extend to up to 110 degrees Celsius. Last but not least, the attached line drawing is suitable for a medium vortex tube.
