Introduction
Congratulations on your purchase of a Labconco Protector® Work Station. 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 fumes and chemicals
when properly installed and operated. Each enclosure uses either a carbon filter
for exhausting low concentrations to the room or an accessory remote blower or
accessory FilterMate Portable Exhauster for exhausting high concentrations to the
outside. The carbon filters are available with three different carbons for adsorbing
organic vapors, formaldehyde or ammonia and amines. The accessory FilterMate
Portable Exhauster can also filter particulates. The Protector Work Stations 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. If you are unfamiliar with how high performance
Protector Work Stations operate, please review Chapter 4: High Performance
Features and Safety Precautions before you begin working in the enclosure. Even
if you are an experienced user, please review Chapter 5: Using Your Protector
Work Station, which describes the features so that you can use the enclosure
efficiently. See chart that follows for application review and contact Labconco for
additional ordering information.

Support, Vibration and Movement
Requirements
At a minimum, the supporting structure usually consists of a base cabinet or base
stand and chemical-resistant work surface. See Chapter 3 for setting up installation.
Location and Air Current Requirements
The Protector Work Stations have been designed to contain hazards by negating
typical cross drafts and turbulence within the opening. Normal air movement does
not affect installation of the Protector Work Station. However, as a precautionary
safety measure and a higher level of quality management, it is recommended that
the Protector Work Station be placed in an area to avoid:
High traffic areas where walking might cause an air disturbance or be a
nuisance.
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.
Ne placez pas l'appareil de sorte qu'il est difficile de faire
fonctionner le dispositif principal de déconnexion.
Exhaust and Blower Requirements
The Protector Work Station draws room air past the operator and through the
enclosure. This contaminated air is either pulled through a carbon filter and
exhausted to the room or exhausted outside by a remote blower.
Data for the exhaust volume and enclosure static pressure loss are listed for the
Protector Work Station at face velocities of 60, 80 and 100 fpm.
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 and transition adapters listed in Chapter 7.
Labconco also offers accessory FilterMate Portable Exhausters 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 enclosures. See Chapter 7 for
accessory Adjustable Damper ordering information.
Electrical Requirements
Standard duplex electrical receptacles should be nearby for connecting the
enclosure or other equipment. The enclosures for remote blower exhaust include
iris pass-throughs to allow electrical cords through the back of the enclosure
without leaving a large hole for contaminants to escape.
The remote blower for the Protector Work Station may be connected to the blower
switch on the enclosure. There is an outlet on the back of the upper light housing
for this specific purpose. We recommend a maximum amperage of 6 amps for this
circuit to the remote blower. Please refer to the wiring diagrams in Appendix C.
Connect the blower wires to the remote blower per local electrical codes.
Space Requirements
The dimensions for the different models are shown in Appendix B: Dimensions.

Installation of Carbon Filters for Room
Exhaust
For carbon filter installation, first unthread the knobs on the perforated baffle
located inside the enclosure in the upper corners. Use caution when slowly
lowering the perforated baffle. See Figure 6-4 in Chapter 6 for location of the
perforated baffle and knobs. See the following list of available carbon filters
below and in Chapter 7. All carbon filters are simply installed with the gasket side
on the downstream exhaust side. Install the correct carbon filter for the application
and call Labconco for assistance. Two carbon filters must be installed behind the
perforated baffle. These two filters provide additional capacity and mixing of the
air stream for proper performance. If using both a formaldehyde filter and organic
vapor filter at the same time you must place the formaldehyde filter downstream of
the organic vapor filter. (With the perforated baffle tilted down, the formaldehyde
filter is on top of the organic vapor filter.)
Important: Carbon filters do not provide any particulate
protection, but provide odor control for low level
concentrations below OSHA recommended time weighted
averages.

Connecting the Electrical Supply Source
to the Enclosure
115V Models
Simply connect the 115V power cord supplied to the IEC electrical supply plug on
the back of the enclosure, then connect the integral blower power cord from the
motorized impeller outlet on the exhaust to the back of the upper light control
panel. If operating at 50 Hz operations, integral blower performance maximum
airflow will be reduced by 17%. See Figure 3-4 on the following page.
For the remote blower used for Protector Work Stations, follow the wiring diagram
in Appendix C and wire the remote blower wires to the switched outlet on the back
of the upper light control panel. These wires are switched by the blower switch.
Refer to Figure 3-5.
The maximum circuit load for the blower is 6 amps. The lights and airflow
monitor are powered from a standard duplex electrical receptacle located nearby
for connecting the power cord. All wiring for the Protector Work Station should
be performed by a licensed electrician and conform to local codes. In most cases,
the remote blower Protector Work Station for use with a remote blower will
require the use of an additional power cord routed from the switched power outlet
on the back. See Figure 3-5 and power cord, item 24 in Figure A-2. Modify the
power cord, item 24, in Figure A-2 for connection to the remote blower via a
customer supplied junction box located nearby. The grounding connection shall
not be made to the terminal box cover of the remote blower. The building
electrical supply system for the remote blower should include overload protection
such as a switch or circuit breaker in close proximity and within easy reach of the
operator. The switch or circuit breaker shall be marked as the disconnecting
device. Consult NEC-2002 for proper installation.

Set the Face Velocity with the Speed
Control Adjustment
For Protector Work Stations with integral blower, adjustment of the speed control
gives the correct face velocity and is located behind the upper light control 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
appropriate for the application will give the quietest operation. Face velocity
measurements are made using an anemometer. An electric anemometer can be
obtained from your laboratory supply dealer. Face velocity measurements should
be taken in accordance with the Industrial Ventilation Manual. (See Appendix E)
Using a small Phillips screwdriver, adjust the speed control to give the required
face velocity. See Figure 3-4 to locate the speed control. The face velocity is
increased by turning the speed control counter clockwise and clockwise to
decrease face velocity.
Validating the Protector Work Station
Enclosure
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. A total of eight readings are taken for the 4' enclosure and then averaged.
Refer to Chapter 2 for proper airflow volumes for your particular model.
The Protector Work Station enclosures have been tested at Labconco’s airflow test
facility per ASHRAE 110-1995. (See Appendix E) 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. While no
enclosure can compensate for improper technique, these tests confirm that the
Protector Work Station enclosures provide a safe working environment.

NOTE: Face velocity profiles and smoke testing should be
performed frequently per your organization’s quality system to
ensure safe performance.
Sealing the Enclosure to the Work
Surface
When the enclosure has been set in place it may be sealed at the work surface to
prevent spilled materials from collecting under the walls. A bead of silicone
sealant is recommended to seal the enclosure to the work surface.

High Performance Features
The patented1 Protector Work Stations are 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
enclosures have been tested to effectively contain toxic and noxious materials
when properly installed and operated. What makes the enclosures so unique is the
revolutionary way they direct air into and through the contaminated air chamber.
Labconco engineered the enclosures 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 Protector Work Station with integral blower is designed only for low-level
concentrations for use with carbon filters and exhausting to the room. The
Protector Work Station for use with a remote blower is designed for high-level
concentrations for exhausting to the outside.
