THEORY OF OPERATION
DuraVent’s HEPA Tower was designed to greatly minimize exposure to airborne pathogens, pollen and
dust by quietly filtering the air in the room. The design intent was to create a mobile HEPA filter unit that
would quietly filter any room, work space, office space, conference room or waiting room to minimize
the airborne transmission of viruses, viral particles, and removal of pollen, fungal spores and dust, that
can accumulate in indoor air. This portable unit recirculates and filters the air (HEPA=99.95%) in the
space it has been placed.
It works by pulling in contaminated air from low in the room, passing the air through a Merv 11 pre-filter
and Medical Grade HEPA Filter and pushing the air up high thus creating an airflow pattern (High to
Low) that reduces human exposure to contaminants.
The HEPA TOWER Design Requirements:
•
Pre-filter: High quality MERV 11 pre-filter
• This HEPA Filter is rated at 99.95% efficiency [individual test certificate] which offers 99.95%
arrestance at 0.3 micron particle size. HEPA standard uses 0.3 microns as the "lowest point". This
means that the filtration efficiency increases for particle diameters both less than and greater than
0.3 microns.
• ECM Motor (High Efficiency) to quietly produce high volume airflow in ten speed steps (with optional
remote control) capable of medical grade room air changes per hour.
• Adjustable Louvered Air Exit, which allows you to direct the filtered air in 4 directions to create the
optimum airflow pattern through the room. Correct Air Flow will minimize Low Flow Areas in the room.
PURCHASE OPTIONS (not included)
A wireless remote is an available accessory option for DuraVent’s HEPA Tower. The wireless remote is
NOT included as part of this fan’s standard control package. The yellow manual included with these
accessories provides specific instructions for the installation and operation of the remote.
If purchased
, the wireless remote receiver is connected to the fan electrical box at the blue RMT RJ45
port. Installation means removal of the rear panel, installation of the remote receiver and blue Cat5E
cable, a operational test and reinstalling the rear panel.
SAFETY INFORMATION
• The HEPA TOWER does NOT remove gasses.
• The HEPA TOWER is not for use in professional kitchens.
• Before servicing the Tower, unplug the fan from the wall receptacle to reduce the risk of damaging
circuit boards, fire, electrical shock, or injury.
• A used HEPA Filter should be treated as “infected” or contaminated and discarded taking
precautions. Avoid touching the filter material.
• Perform periodic checks of the air flow pattern, physically feel air moving in and out of the HEPA
Tower and around the room.
• When installing a new HEPA Filter avoid touching the filter material as this may damage (create a
hole in) the HEPA Filter and thus nullify the HEPA standard.
