Subject: Laboratory Vacuum Cleaner for sensitive equipment

Folks, 
Does anybody have an idea for such a vacuum cleaner described below?:  
thanks, 
Eric Clark, MS, CCHO, CHMM 
Safety Officer
Los Angeles County Public Health Laboratory

We are considering the acquisition of a standard-sized (or compact) 
upright or canister-format vacuum (I. e. dust cleaner for cleaning dry 
dust, etc). This pertains to the need for internal housekeeping at 
hard-to-reach lab bench areas as well as deep inside large sensitive 
electronic equipment. Are there any recommendations about the type of 
vacuum that may be used in a chemical or microbiological lab, and are 
there any particular safety regulations which need to be addressed in such 
a purchase. (I. e. does such a unit have to contain a built-in HEPA filter 
component?).  
Thanks,
