Creating The Portable Clean Room

Creating a room that meets the criteria considered class 1000 ( maximum of 1000 particles per cubic foot at 0.3 microns) usually requires special construction and an air handler system that includes HEPA filters and a motor/blower system capable of moving 2,000 CFM or higher of filtered air in a positive pressure environment. This design is both expensive and takes a fair amount of time to construct.

Using one of the larger HEPA Shield systems, made by Pure Air Systems, would provide a system that could be easily convert any room into a clean room or temporary surgery suite. The 2000HS unit comes with a 1HP programmable, variable speed drive motor, prefilter, carbon media filter and true, commercial grade 99.99% scanned HEPA Filter. The 2,000 CFM unit can be placed in the ceiling area or along the top of a wall attached to sections of sheet metal ductwork with diffusers located in various parts of the ceiling area. When the unit is operational it will be pushing 2,000 CFM of filtered air into the enclosed space. This will pressurize the room so that when a door is opened into the room the air will move out of the room creating a positive pressure seal of sorts. In this way no airborne contaminants are allowed to enter the room. 

This concept has been used in third world countries where almost any building can be turned into a quasi-clean room or semi-surgery suite for under $3,000.00. In addition, all of the filtration systems from Pure Air Systems are rated at 120/240Volt 50.60Hz.making them suited for any location anywhere in the world.

Better Safe Than Sorry

A simple phrase that has been used millions of times for over a hundred years. Often told to children by their parents, the “better safe than sorry” statement allowed you to have someone use a safer material or wear some protective cloths or even buy travel insurance just to be on the safe side. Of course for those who throw “caution to the wind” this phrase is merely another reason to have to follow some stupid rule.

The new APPAIS unit, from Pure Air Systems, is a new design of the portable HEPA unit designed to be used in conjunction with injections given by Pharmacists, Nurses, Doctors and Clinicians in any environment that is not antiseptically clean. ( which are most environments). This unit has the ability to maintain a clean pocket of air that surrounds the area of the arm or body that will be injected.

Injections are relatively simple, but they process is not really done under any particular guidelines. With more injections being done in Pharmacies, Walmarts, Retail Medi-Centers, etc, etc, you have individuals who are having their skin punctured in environments that are far from being clean and that are contaminated by people, products and an assortment of airborne pathogens that would make you shutter if you actually knew what was in the air. And this is where you will get punctured or injected.

The APPAIS unit uses commercial grade HEPA filters that are 99.99% effective on particles 0.3 microns and larger and approach 98% efficiency on particles smaller than 0.3 microns. The system has been recognized by the FDA to provide an Iso 6 environment ( less than .05 % ) particulate at 0.3 microns or larger 40″ from the face of the unit. This means the injection site is in an environment that is very close to that of a surgery room. Now,  wouldn’t you want to have your injection with the APPAIS unit rather than next to a rack of candy, books or other materials?

Capping Off A Clean Environment For Your Favorite Beverage

The next time you pop off, twist off or pull off that cap from your favorite beverage bottle keep in mind that you are about to put your mouth around a glass surface usually without even thinking about it. Wow! Really? Yes.

When we live in an era where people are using disinfectants for their hands, wipes for any kitchen or eating surface it is interesting how much trust we have in placing that screw top bottle into our mouths without a second thought about where it has been.

To be fair, the bottling process for any beverage that is sold in the retail market is strictly controlled by state and federal regulations. Interestingly, the actual filling of the bottle with the liquid and capping process are actually done in a class 10,000 or better clean room environment.

When the term Class 10 , 100, 0r 10,000  is used, it usually means that the area, when measured for a certain sized particulate per cubic foot, needs to be at or below that required Class rating. And the rating is significant.

For example, a Class 10 rating means that when tested with the correct digital equipment the area only has 10 particles per cubic foot at a 0.3 micron level. This is clean room clean. For comparison, your home environment probably has a level exceeding 300,000 particles per cubic foot at 0.3 microns. Big difference.

Understand that most bottling plants are large factory like structures using large process equipment, conveyor belts and equipment transfer stations; for the most part a fairly dirty environment. In order to keep the actual bottling process areas (filling stations) within the required class ratings they have to use HEPA filtered air to either wash the bottles as they are being filled or maintain a class rating for the entire bottling room.

Pure Air Systems has provided a number of its commercial grade HEPA filtration systems for these bottling applications. The PAS product line includes HEPA systems rated from 300 CFM to 2000 CFM all using variable speed motors for finite HEPA air volume control.

The PAS HEPA units are small enough to be placed close to ( less than 12″) the actual filling station and wash the liquid filling process with HEPA filtered air so that no airborne contaminants will enter the bottle or cap during the filling and capping process.

So the next time you get ready to take a drink of that cold soda or brew, you’ll be comforted to know that the cap and bottle top were HEPA filter clean when they left the bottling plant.
