Introduction
Congratulations on your purchase of a Labconco XPert® Nano Enclosure. Your
enclosure provides personnel protection through superior containment while
conserving energy at OSHA approved velocities as low as 60 feet per minute. It is
the result of Labconco’s more than 50 years of experience in manufacturing fume
hoods and more than 30 years of experience in manufacturing filtered enclosures.
These enclosures will effectively contain toxic or noxious particulates when
properly installed and operated. Each Nano Enclosure uses an ULPA filter, which
is rated at least 99.999% efficient for 0.12-micron particles. The XPert Nano
Enclosures offer many unique features to enhance safety, performance, and energy
savings. To take full advantage of them, please acquaint yourself with this manual
and keep it handy for future reference. The XPert Nano Enclosures include a true
bag-in/bag-out ULPA filter to properly protect personnel during filter changing
operations.
If the unit is not operated as specified in this manual it may
impair the protection provided by the unit.

Chapter 2:
Prerequisites
Before you install the filtered enclosure, you must be certain that the area is level
and of solid construction. In addition, a dedicated source of electrical power
should be located near the installation site to power the filtered enclosure.
Additionally, the enclosure should be strategically placed in the lab to provide
efficient workflow.
Carefully read this chapter to learn the requirements for your installation site:
The support, vibration and movement requirements.
The temperature variation requirements.
The humidity and static electricity requirements.
The location and air current requirements.
The exhaust and blower requirements.
The electrical power requirements.
The space requirements.
Refer to Appendix B: Dimensions for complete enclosure dimensions.
Refer to Appendix C: Specifications for complete filtered enclosure electrical and
environmental conditions, specifications and requirements.
Support, Vibration and Movement Requirements
At a minimum, the supporting structure usually consists of a base cabinet or stand.
For weighing applications the ability for analytical balances to accommodate
vibration varies with type and brand. More advanced balances have improved
tolerance, however in the preparation of a balance enclosure site, please consider
the following:
Avoid tubular stands or mobile benches that have the potential of moving
when touched.
A bench that is rigidly mounted to the floor or fixed to the wall, but not both,
may be appropriate.
Product Service 1-800-522-7658
Chapter 2: Prerequisites
4
The corners of a building typically have less vibration than the center.
The bench with the balance enclosure should not contain any vibration-
producing equipment, such as shakers or pumps.
Marble slabs with dampening pads placed within the enclosure are also an
effective low cost means of controlling vibration.
The balance should be calibrated and verified at least annually; for best
results, the balance should be calibrated inside the enclosure while running at
the desired face velocity.
Temperature Variation Requirements
The extent the balance readings are influenced by temperature variations is a
function of the balance design. Most manufacturers would suggest that a
temperature drift of 1-2°C is generally tolerable. Only validation through your
Operational Qualification protocol can define what is acceptable. To minimize the
potential for temperature variations:
Never install balances near heating sources such as radiators and hot plates.
Do not place the balance and enclosure on a bench that would receive direct
sunlight.
Humidity and Static Electricity Requirements
Electrostatics can be troublesome in a balance enclosure. It is important to
understand and, to the extent possible, control static charges. An electrostatic
charged vessel, sample or enclosure can apply forces and lead to errors in
weighing. The repulsion or attraction can be detected with micro, semi micro and
analytical balances. Static charges can also lead to particulates being attracted to
surfaces within the balance enclosure. Containment of harmful powders,
prevention of cross-contamination and clean-up is enhanced when static attraction
of powders is minimized. The construction of the XPert Nano Enclosure avoids
the use of plastics, which are highly insulative.
To correct or ensure against electrostatic issues, the following additional measures
may be prescribed to improve weighing operations.
Maintain a humidity level between 45 and 60%. The ability to sustain this
humidity range can be challenging depending upon the regional climate and
HVAC system.
The XPert Nano Enclosure is offered with a factory installed ionizer which
will neutralize surface charges.

Background on Electrostatics or Static Electricity
Electrostatic charges on a surface such as the wall of a balance enclosure are not
created by moving air. Impurities within the air impinging upon surfaces dictate
the polarity and magnitude of the charge. The process, triboelectrification, occurs
when the dust particles contact the surface, creating friction and electrons move
across the interface.
The ability of a material to become polarized is a property known as permittivity.
On highly insulative materials like acrylic, ions or charged molecules are strongly
bound to the surface by polarization forces. The higher the force, the higher is the
permittivity value of the material. It is suggested by balance manufacturers that
the use of high permittivity materials, such as plastic be avoided.
Since static electricity is a surface phenomenon, materials can also be classified by
their surface resistivity measured in ohms per square. The table below lists the
surface resistivity of various classes of material.
Surface Resistivity Table
Location and Air Current Requirements
The XPert line of Filtered Enclosures have been designed to contain hazards by
negating typical cross drafts and turbulence within the opening. Air movement
does not affect most modern balances with draft shields. However, as a
precautionary safety measure and a higher level of control, it is recommended that
the enclosure be placed in an area to avoid:
High traffic areas where walking might cause an air disturbance or be a
nuisance to balance readings.
Overhead or wall HVAC diffusers, fans, radiators or other lab equipment
producing air currents.
Next to doorways or windows that may be opened.
Do not position the unit so that it is difficult to operate the main
disconnect device.

Exhaust and Blower Requirements
The XPert Nano Enclosure uses an integral motorized impeller to draw room air
past the operator and through the enclosure. This contaminated air is then pushed
through the ULPA filter. The ULPA-filtered exhaust air is then forced out the top
of the enclosure.
The ULPA-filtered exhaust air can be recirculated into the laboratory or exhausted
outside with the addition of the Canopy Exhaust Connection and remote blower
listed in Chapter 7. Electrical connections are covered in Chapter 2 for this
configuration. Consult your local regulations or guidelines for ventilation of the
filtered exhaust in nanoparticle applications.
If external exhaust is required, data for the exhaust volume, noise pressure and
enclosure static pressure loss is listed for each filtered enclosure model at face
velocities of 60, 80, and 100 fpm. Weighing and handling nano materials is best done
with lower flow rates (60-70 fpm or 0.31-0.36 m/s).
Proper blower selection can be determined from these exhaust requirements and the
total system static pressure loss. For outside exhaust, the enclosure must be
connected to either a dedicated blower or a house exhaust system. Labconco offers
accessory remote blowers listed in Chapter 7. Contact Labconco for blower sizing
assistance.
If the enclosure is connected directly to a house exhaust system, an
adjustable damper (or valve) must be installed to control the airflow
properly. This is equally important when a house exhaust system is
controlling multiple filtered enclosures. See Chapter 7 for accessory
adjustable damper ordering information.

Electrical Requirements
Standard duplex electrical receptacles should be nearby for connecting the filtered
enclosure, or other equipment, such as a balance for weighing operations. The
enclosures include iris pass-thru to allow electrical cords through the back of the
enclosure without leaving a large hole for contaminants to escape.
Space Requirements
The dimensions for the different models are shown in Appendix B: Dimensions.

Connecting to the Exhaust System (Optional)
ATTENTION: The weight of the exhaust ductwork system
must be supported independently of the enclosure
superstructure or damage may occur.
The exhaust system should be installed by a qualified HVAC
contractor.
The exhaust connection on the 2', 3' and 4' XPert Nano Enclosure have been
designed to accept 6" diameter ductwork as shown in Figure 3-2. The 5' and 6'
models have been designed for 10" diameter ductwork as shown in Figure 3-3.
For the 2', 3' and 4' sizes, the exhaust connection ships uninstalled on the top and
needs to be fastened with the screws provided. See Chapter 7 for ordering Canopy
Exhaust Connection. Canopy Exhaust Connection aids in the removal of
chemicals or applications where a higher degree of powder and particulate removal
is required. Review Chapter 2 for exhaust prerequisites and review Chapter 7 for
ordering blower exhaust equipment.

Connecting the Electrical Supply Source to the
Nano Enclosure
Simply connect the 115V power cord supplied to the IEC electrical supply plug on
the back of the enclosure. If using at 50 Hz operations, blower performance
maximum airflow will be reduced by 17%.
The same procedure applies for the 230V except it is shipped without a plug.
Install the appropriate plug for your electrical specifications per local codes. All
models use less than 5 amps.
All wiring for the XPert Nano Enclosure should be performed by a licensed
electrician and conform to local codes.
Do not use any detachable power cord that is not adequately rated
for the unit.
Ne pas utliser un fil électrique amovible qui n’est pas du tension
nominale de l’appareil.
Set the Face Velocity with the Speed Control Adjustment
Adjustment of the speed control gives the correct face velocity and is located behind
the front panel. The face velocity should be adjusted from 60 to 100 fpm. (Consult
your Safety Officer for airflow recommendations for your application). Containment is
maximized at a setting within this range. Working at the lowest face velocity
permissible for the application will give the least turbulent, quietest operation. Face
velocity measurements are made using an anemometer. An electric anemometer can be
obtained from your laboratory supply dealer.
To determine the actual face velocity at the sash opening, airflow velocity readings
are taken. This should be done across the sash opening of the enclosure in
accordance with the Industrial Ventilation Manual. (See Appendix E) The
“average face velocity” is achieved by taking readings in two rows across the
enclosure with the readings 6" from the ends and evenly spaced every 12"; the first
row is 3" down from the upper sash foil and the second row is 3" up from the work
surface. Refer to Chapter 2 for proper airflow volumes for your particular model.
The XPert enclosures have been tested at Labconco’s airflow test facility per
ASHRAE 110-1995. All enclosures achieve an “as manufactured rating” of less than
0.05 part per million (ppm) at 4 liters per minute (lpm); AM <0.05 (Consult
Labconco for individual ratings). For “field use” ASHRAE testing contact Labconco
for a certified on-site contractor. For particulate powder validation, Labconco
performed containment testing to validate the enclosures for sodium naproxen
powders. The XPert enclosures demonstrated excellent containment when used by an
operator using excellent technique and good containment when used by an operator
using marginal technique. While no enclosure can compensate for improper
technique, these tests confirm that the XPert Nano Enclosures provide a safe working
environment.

High Performance Features and
Safety Precautions
High Performance Features
The patented1 XPert Nano Enclosure is designed to meet the needs of the
laboratory scientist, and provide superior containment while conserving energy at
OSHA approved “low flow” velocities as low as 60 feet per minute. The filtered
enclosures have been tested to effectively contain toxic and noxious materials
when properly installed and operated. What makes the Labconco line of
enclosures so unique is the revolutionary way they direct air into and through the
contaminated air chamber. Labconco engineered them to minimize the effects of
turbulence. The containment-enhancing and aerodynamic designs of the upper
sash foil, side air foils, lower air foil, upper dilution air supply, and rear perforated
baffle all work in concert to produce horizontal airflow patterns that significantly
reduce powder, chemical and particulate concentrations through the work area.
These concentrations of materials are predominantly removed on the “first pass” of
airflow through the chamber resulting in high performance containment.
The plenum and the ULPA filter are jacketed by negative pressure. Should a leak
occur in the filter gasket or the plenum, the contaminated air is recaptured and
refiltered.
The XPert Nano Enclosure includes a true bag-in/bag-out ULPA filter disposal
system to protect the worker from contact with hazardous powders and
particulates. Users are encouraged to routinely check airflow with the use of the
airflow monitor.
