CHAPTER 1 – BASIC PRODUCT INFORMATION
CHAPTER 1
BASIC PRODUCT INFORMATION
Ductless fume cabinets provide operator protection by removing chemical fume contaminants within the
work area They are suitable for most common chemical work (Note that ductless fume cabinets are
NOT suitable for all chemical application Please consult Esco for advice concerning your individual
application) The Esco Ascent Opti Basic/Ascent Opti Ductless Fume Cabinets are our new-improved
products which offer the best combination of performance, quality and cost-effective in the market today
1.1 BACKGROUND
Conventional ducted fume hoods provide safety to laboratory personnel by drawing air across a front
opening in the hood at a controlled rate, thus preventing any toxic vapours generated during the
experimental procedure from escaping into the general laboratory environment
Air is then exhausted via a fan system to the outside of the laboratory, usually via an outlet mounted on
the roof of the building When released to the external atmosphere in this manner, chemical fumes and
vapours, which would have otherwise been toxic in the enclosed environment of the laboratory, are
diluted many times over and have an insignificant effect on the environment
Ductless fume cabinets are quickly becoming a viable alternative to conventional fume hoods Unlike
conventional fume hoods, these cabinets filter out chemical fumes and recycle air directly back to the
laboratory Personnel protection is provided in a manner similar to conventional fume hoods by drawing
air at a controlled rate across a front opening into the hood Ductless fume cabinet has many advantages
over conventional fume hoods:
• They protect the environment since toxic fumes are not released to the environment unlike in the
conventional fume hoods
• Fully installed systems ready to operate are available at a lower cost than bulky conventional
fume hoods
• An expensive ducting and external blower system that is often difficult to maintain is not
required
• They are mobile and can be relocated easily to meet your changing needs; perfect for schools
and education institutes
• They allow energy saving since air which is costly to air condition or heat is not removed from
the laboratory
In order to gain a better understanding of their benefits, let us examine how these hoods filter out
chemical fumes generated during experimental procedures conducted in the laboratory Esco’s ductless
fume cabinet incorporate a state-of-the-art vapour phase activated carbon filter system, which is the
primary filtration component in removing all chemical fumes from within the hood before air is re-
circulated back to the laboratory
Activated carbon is a porous material manufactured from carbon-based raw materials These include
coal, peat, coconut and wood The activated process develops pores of molecular dimension within the
carbon particles These give the carbon an extremely high internal porosity and surface areas Typically,
activated carbons contain surface area in the range of 500-2000 m
2
/g
The basic mechanism through which activated carbon removes impurities from contaminated air
saturated with chemical fumes is referred to as physical adsorption Physical adsorption is a
phenomenon resulting from electrostatic forces of attraction (van der Waal forces) between the impurities
and the internal surfaces of the activated carbon Activated carbon has the strongest physical adsorption
forces or the highest volume of adsorbing porosity of any material known to mankind
The safety of personnel in the laboratory has always been of significant importance Similarly it is
important to consider the factors affecting the efficiency of activated carbon filtration in order to ascertain
the ability of the technology to provide a safe solution in the laboratory

USER SECTION
CHAPTER 1 – BASIC PRODUCT INFORMATION
Activated carbon filters are suitable for use with many chemicals but this is dependent on a number of
factors In general, chemicals with a relative molecular weight over 30 and a boiling point higher than
60
o
C or 140
o
F can be adsorbed with a relatively high efficiency by activated carbon filtration
Further variables include the amount of vapours being generated in the hood either through general
evaporation or as a direct result of experimental procedures Naturally, the lower the concentration of the
chemical or the amount released in the hood in vapour form, the lower the safety risk to personnel Other
factors involving the nature of the chemical(s) used in the fume hood play a role For example, larger
molecules are adsorbed more easily by activated carbon In addition, less soluble compounds are
adsorbed more easily than more soluble compounds In the case of organic compounds, branch-chain
organics are more easily adsorbed than straight-chain organics
Environmental factors may also affect the adsorptive efficiency of the hood The ambient temperature of
the laboratory and the gas must be kept to a minimum The higher the ambient temperature the lower the
adsorptive efficiency of the carbon filters Relative humidity must also be kept to a minimum since an
especially high relative humidity can cause the activated carbon filter to adsorb water molecules in place
of chemical vapours
The construction of the filter also affects the adsorption efficiency of the hood A filter with a thicker
media bed will have a longer contact time in which a larger amount of chemical vapour will be deposited
in the filter by physical absorption
1.2 AIRFLOW PATTERN INSIDE THE CABINET
1.
An inflow air curtain from the
ambient environment into the
cabinet with an average velocity of
0 5 m/s or 100 fpm is induced by
the cabinet blower system
2.
The inflow flushes the entire work
zone of the cabinet; within the main
chamber of the cabinet; negative
pressure (relative to the ambient
environment) is maintained in order
to ensure that no chemical fumes
or vapours escape the work zone
3. Air is t
aken through an activated
carbon filter mounted in the interior;
this removes all fumes from the
exhaust air stream; exhaust air is
re-
circulated directly back to the
room from the top of the cabinet
2 Inflow flush work zone
1 Inflow air provide
operator protection
3 Exhaust air is carbon
-
filtered providing

Chapter 2 – UNPACKING YOUR CABINET
CHAPTER 2
UNPACKING YOUR CABINET
This chapter aims to provide relevant information on how to handle the cabinet properly upon receipt
Failure to follow the following instructions may cause damage to the cabinet We strongly advise you to
read this chapter carefully before proceeding further Relevant information on Warranty Terms and
Conditions can be found on page 7
2.1 STEP-BY-STEP PROCEDURE
1 Inspecting the corrugated cardboard box
Upon receipt of your new cabinet, inspect the cardboard box If there is any visible damage to the
exterior of the box please refer to freight claim information on page 6
2 Moving the cardboard box
a The corrugated cardboard box has been designed to protect your cabinet from external impact
However, excessive impact on the box may damage the cabinet too Hence all care should be
taken to protect the box from direct impact during the course of moving it
b While lifting and moving the box, please ensure that the floor jack or mechanical lift truck has
entered fully under the box so that the box can be lifted stably Otherwise there would be a risk of
the box falling off from the floor jack or mechanical lift truck during handling Whenever needed,
please use suitably long extension bars
c While the box is being moved, there should be adequate gap between the ground and supports of
the pallet The pallet should not be dragged on the ground as it would damage the pallet and
possibly the cabinet too
3 Removing the strapping
a Remove the strapping by cutting it
b Do not discard the packaging material of your cabinet until you have fully installed and tested
the unit along with all its components
4 Opening the box
a If the unit is bundled with a support stand, you would find it strapped on top of the main cabinet
box, and onto the pallet
b Unwrap the protective plastic wrapping which covers the main box and the support stand box (if
present)
c If straps are present, cut them now
d Open the top cover of the box by cutting the masking tape
