Alternative to “Dust Off” Approach

Hey Everyone, I was wondering if anyone could direct me to a vendor site in which I could purchase a air compressor that is suitable for computer cleaning use to take out all dust and dirt and other things that shouldn’t be inside the PC. My current company uses cans of air, mostly the Dust Off brand by the case load. I am looking for a portable solution, in which a compressor could be charged up and carried around. Does anyone currently use a similar approach to cleaning PCs? Please direct me to a web site or other reference where I could purchase a suitable PC air compressor. Thanks for your time.
