Page 5: Introduction
1. Introduction The Meech Air Technology Stainless Steel ColdStream Air Gun provides a cold airflow commonly used for spot cooling. At the heart of the ColdStream Gun is the Vortex Tube which is encased in a hot and cold end silencer. Cold air produced by the Vortex is directed to specific area through knuckle trucking. -
Page 6: Safety And Inspection
2. Safety and Inspection All Meech products are packed carefully at our factory. Nevertheless, we recommend careful examination of the carton and contents for any damage. To protect yourself and others when using compressed air, you should be aware of the following general safety guidelines: Warning –... -
Page 7: Maintenance
3. Maintenance The Meech Coldstream Gun has no moving parts, making them virtually maintenance free. Clean and dry compressed air moving through the Coldstream Gun will not cause wear on any of the components. Occasionally dirt, water or oil may enter the Coldstream Gun from the compressed air supply, which could hinder performance. -
Page 8: Compressed Air Supply
4. Compressed Air Supply It is recommended to use a 5-micron (or smaller) filter to remove water and dirt from the compressed air supply. A 5 micron filter will remove 99% of foreign material from the air supply; the use of an oil filter with an effective filtration of 0.01 ppm will remove the oil droplets for an even cleaner compressed air supply. -
Page 9: Compressed Air Line Sizes
5. Compressed Air Lines Sizes Figuring the correct pipe size for your compressed air system is an important task. Pipe that is sized too small can create big pressure losses and reduce operating efficiency. Many people who plan the piping never consider the fittings or the future. FITTINGS: Every pipe fitting creates a certain amount of increased frictional air loss that is equal to a specified length of pipe. - Page 10 Take that pipe size to TABLE 2 and use the table to find all the EQUIVELENT LENGTHS OF PIPE needed for each PIPE FITTING. Write these lengths on your piping schematic at each fitting. TOTAL all the EQUIVELENT LENGTHS OF PIPE needed for each PIPE FITTING and add to your total of straight length of pipe.

Page 12: Installation
6. Installation All Meech Coldstream Guns are fitted with a strong magnet allowing it to be fitted to any surface that will hold the magnet. The magnet can be removed by unscrewing the hot end silencer and removing the nut holding the magnet in place. -
Page 13: Operation
7. Operation Coldstream Gun All Coldstream Guns are set to deliver the most efficient cooling possible. Coldstream Guns are factory set to 70% cold fraction at 80psi (5.4 Bar). As standard they are fitted with a Red 15 cfm Generator, so approximaty 10cfm of cold air will exit through the cold end of the Coldstream Gun. - Page 14 To change the Generator, simply unscrew the cold end silencer (the end the knuckle trunking is fitted to). You will then need to remove the cold cap from the Vortex Tube. You can simply unscrew this from the ColdStream Gun. Inside you will find an O’ring and Generator. Finally remove the generator and replace with new generator, please also remember to fit the original O-ring.

Page 15: Adjustable And Non-Adjustable
Adjustable and Non Adjustable ColdStream Guns The Coldstream Gun is available in either an adjustable or non-adjustable version. The non-adjustable version is factory set at 80psi (5.4 Bar) to 70% cold fraction. The only way to adjust this is by changing generators. The Adjustable version of the Coldstream features a control knob that allows fine- tuning of the volume of hot air exiting the Coldstream Gun. -
Page 16: Flexible Knuckle Trunking
Both the single and double hoses come with a standard round ¼” or 1/2” nozzle. There is also a range of spare parts these include a range of flat nozzle in various sizes and additional knuckle trunking to increase the length of the flexible trunking. For more information please contact the Meech office. -

8. Troubleshooting Air Flow Problems with compressed air flow can be caused by: Air pressure too low – increase air pressure at the relevant regulator. Undersized compressed air lines – replace pipes with correct sizes, see section 5. Blocked compressed air line – remove blockage.
