Purafil Safeguards the Largest Museum inAfrica and the Middle
East
More About the MohamedMahmoud Khalil MuseumPurafil protects the
largest collection of fine artsin Africa and the Middle East from
environmen-tal pollution in the expansion of the MohamedMahmoud
Khalil Museum in Giza, Egypt. Theart collection is worth billions
of dollars andrequires constant protection from a pollutedurban
atmosphere.
The ProblemGaseous pollution is primarily caused by theburning
of automobile fuels. If these pollutantsare drawn indoor through an
HVAC system orby natural filtration, museum artifacts can
bepermanently damaged.
The main components of automotive exhaustare sulfur dioxide,
nitrogen dioxide and ozone.Sulfur dioxide combines with moisture to
formsulfur acid, which oxidizes metals and deterio-rates
organic-based materials. Similarly, nitro-gen dioxide dissolves in
water to form nitric acidwhich oxidizes metals and attacks
calcareousstone and murals. In the presence of ozone,organic-based
materials, such as paints, tex-tiles, animal skins and paints, will
discolor andbecome brittle.
Purafil Provides the SolutionKannapell Rodgers Company, the
local Purafilrepresentative, installed Purafils gas-phase
airfiltration systems in order to achieve the follow-ing
objectives:
1) Stop the degradation of valuable artifacts.2) Enable the
museum to bring in temporary,
traveling exhibits.
3) Clean the air for museum patrons and personnel.
Purafils systems were designed for retrofit intothe museums
thirteen air handling units andtogether filter 360,500 CFM of
outside andrecirculation air. And because recirculation airrequires
less energy to heat and cool than ven-tilation air, the museum
saves on energy costs.Housed within each filtration system are
dis-posable modules containing CP Blend media.Purafils CP Blend
media is a 50/50 volumeblend of both activated carbon (Purakol
media),and potassium-permanganate impregnated alu-mina (Purafil
Chemisorbant media). BecausePurakol and Purafil media are effective
atremoving different gaseous contaminants, bothare needed for
complete gas removal.
Purafil Products
Front Access System: Purafils Front System iscomposed of modular
metal frames and mod-ules filled with dry chemical media. The
systemis designed for retrofit into an existing air han-dling unit
and is used in applications wherespace allows for installation in
the direction ofairflow. The frames can be stacked horizontal-ly or
vertically allowing for flexibility in terms ofsize and media bed
depth.
The Commercial Purafil Side Access System:Purafils Side Access
System contains drychemical media, filter tracking, side doors,
andheavy support channels. The system isdesigned for retrofit and
is preferred in applica-tions where space requires access from
theside of the air handling unit, perpendicular tothe direction of
airflow.
Value-Added Service
Kannapell Rodgers Co. made regular follow-upservice calls to
ensure Purafils systems werefunctioning at maximum efficiency. A
test usingcorrosion classification coupons (CCCs) wasperformed to
determine the environments cor-rosive severity level. An analysis
of the CCCsrevealed that the gaseous concentrations werewell within
the levels recommended for safearchival storage.
Museums & Preservation
Product Application
The Mohamed MahmoudKhalil Museum is exposed toheavy traffic and
industrial pol-lution. Recent tests indicate ahigh level of
contaminants inthe surrounding area.
These findings led architectDr. Ali Raafat and ShakerConsulting
Group, the leadingconsulting groups in Egypt, toseek the highest
quality airpurification and monitoringsystems available.
Gabtic International Company,Purafils representative inEgypt,
provided documentedproof of Purafils ability tomeet these high
standards.The Purafil OnGuard 2000Monitor is currently in use
tomonitor the corrosive reactivi-ty level of the indoor
environ-ment.
