All air compressed by cycled or rotated pumps will contain static electricity, unless it has a certain percentage of water vapor... in addition to the other problems. Water vapor seems to reduce the risk of static electricity. Construction workers, automotive shops, ceramic tile workshops, and many others routinely have these pumps. They run equipment, and they clean away dust and debris. Truckers with 18 wheelers also have them. Any container air is required to have adulterants but I have never seen the adulterants in the equipment used by workman or mechanics in the years I worked for the Centers for Disease Control and FDA.
We have seen a large number of ruined computers that were damaged by the use of compressed air in a work shop, or a compression pump. Fifty-four ruined in Southern Arizon last year that we saw in our shops. The pumps are available at every CostCo, Home Depot, Lowes, and other such stores. Huge numbers of technicians and home techs use them to clean computer cases, power supplies, and the like. If the resulting static electricity reaches the wrong components, many electrical components and devices are instantly ruined... beyond repair. Then, of course, there is the risk of fire from use near denatured alcohol and other solvents sometimes used in computer repair. Compressed "air" sold in stores is perfectly safe, from what we have been able to determine, but there are "shop rags" sold by Costco, Lowes, and Home Depot which work just as well.
