Mail Processing Bio Hazard Control

AirMATION unit with inlet hood suspended over mail processing area:

The progressive filtration would consist of the 4" pleated filter. This would remove the larger airborne particles and protect the HEPA or final filter from prematurely clogging.The HEPA or final filter of 99.99% efficiency will filter out particles of 0.3 microns or larger. Anthrax spores by comparisons are 1-2 microns in size. This is a high efficiency, high capacity filter with over 200 sq. feet or surface area. The final filter is a carbon or gas phase cell. It will remove gas phase pollutants from the air stream. Essentially, it removes the gas molecules that are too small for the HEPA filter to capture. The last line of defense is the germicidal UV lamps. These will act as a redundant safety feature and irradiate anything that might by-pass the previous safeguards. It will also keep the inside of the housing free of microbial growth where it irradiates. As it is the last component in the process and not exposed to a direct unfiltered air stream the bulbs will remain clean and not require the periodic maintenance required to clean their surface. This process is the one recommended by the CDC for controlling Tubercle Bacillus and would include the Anthrax Bacillus.

There is no maintenance to the system other than filter removal. A filter indicator light is located at the rear of the unit. It indicates when the static pressure has risen to a point that requires the first filter in the process (pre-filter) to be renewed. When the light remains lighted and a new pre-filter has been installed it is time to change the second filter. It is estimated that the life expectancy of the pre-filter to be 3-6 months, the HEPA filter 12-36 months and the same for the carbon cell. These numbers will depend upon their length of use, the air quality in the facility and how well the pre-filters are maintained. UV lamps require replacement every 12 months. All filters are easily accessible from a side load swing down door and slide into their respective tracks.

This is a very effective source capture mechanism that will intake 180,000 cu. ft. of air for every hour of use. It will constantly provide cleaning of the air and deposit the exhaust or filtered air into the facility. It will not affect existing HVAC systems.

Installation is very simple. The unit must be suspended and power supplied to it, either 115V or 230V. It would be positioned over the area or potential contamination source. Air will be drawn into the hood and any airborne contaminants emanating from the mail process will be segregated from the personnel, removed from the air stream, contained and eliminated.

Units can be repositioned at a later date if required. UV lamps can be installed but only activated if required. Additional vinyl curtains can be installed to hang down from the sides of the hood to further "contain" the pollutants.

The AirMATION units can also be modified to suit your requirements.
