Presto Change-O

In 1939 the term Presto Change-o was inserted into the American lexicon via a Merrie Melodies cartoon about two puppies that run into a house and come upon a magicians trunk. They open the trunk and are tricked time and time again. Each time a different trick is played upon them by the same character.

Having one piece of equipment do multiple things is one of the major features of the HEPA and Carbon based, fan powered air filtration systems offered by Pure Air Systems. Like the magicians trunk , all of the larger  PAS air filtration units can have the same exterior cabinet but totally different interior filter components.  For example; the standard filter configuration for the 600, 1200 and 2000 series units incorporate one commercial grade, certified 99.99% metal framed HEPA filter, one carbon media filter ranging from 5 to 15 lbs and one polyester ring panel prefilter.

If you want to add more carbon media the 1200 and 2000 series units have the ability to add one additional 15 lb carbon filter to up the capacity to 30 lbs. Again using the same cabinet. The 600 series units can only hold one 5 lb carbon pad. If, however, you want to use the PAS units for adsorption of odors and gases only and have no need for the HEPA filter you can simply remove the HEPA and put all carbon media in its place. All three units have that capability. This means you can quickly change the HEPA unit to an Odor Adsorption, all carbon media  unit in a matter of minutes. Presto Change-o.

Also, for applications where filtration is required and the removal of the fine, sub-micron particles is not necessary, you can install an ASHRAE grade filter in-lieu of the HEPA for removal of larger particulate. Again, same cabinet and this process can be done in the field in minutes.

Pure Air Systems products are unique in this area. Most air filtration systems are configured with one standard filter package with minimal filter changes, if any. The real benefit here is that customers who purchase the PAS systems in a certain configuration for a specific project, have the options of quickly changing the configuration if their project needs change or if they want to use the product in another location. This not only saves time but also money. And it can be done by almost anyone and the only tool required is a screw driver.

So the next time you have a particulate or gaseous odor problem and you would like them to disappear, contact Pure Air Sysetms and see what magic they can do for you.
