Congratulations on your purchase of a Labconco Purifier®
Vertical Clean Bench. Your enclosure provides product
protection. It is the result of Labconco’s more than 30 years
experience in manufacturing filtered enclosures.
These enclosures will effectively provide product protection from
airborne particulate matter. During operation, room air is drawn
through the prefilter on top, forced through the blower and then
through the HEPA filter and diffuser. The clean air in the work
area in the enclosure meets or exceeds ISO Standard Class 5
conditions defined per ISO Standard 14644-1 and Class 100
conditions as defined by Federal Standard 209E. The enclosure is
set to deliver nominal downward airflow of 40-55 feet per minute.
Each enclosure uses a single HEPA filter, which is rated at least
99.99% efficient for 0.3-micron particles. The Purifier enclosures
offer many unique features to enhance performance. 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
filtered Vertical Clean Benches operate, please review Chapter 4:
Performance Features and Safety Precautions before you begin

Chapter 2: Prerequisites
Support, Vibration and Movement
Requirements
At a minimum, the supporting structure usually consists of a base
cabinet or base stand and chemically-resistant work surface.
Location and Air Current
Requirements
Purifier Vertical Clean Benches have been designed to provide
particulate-free clean air meeting Class 5 conditions by negating
typical cross drafts and turbulence within the opening. However,
as a precautionary safety measure and a higher level of quality
management, it is recommended that the clean bench be placed in
an area away from:
• 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.
• Doorways or windows that may be opened.
Airflow Specifications
Purifier Vertical Clean Benches use an integral motorized impeller
to draw room air from the top and through the enclosure. This
room air is then pushed down through the HEPA filter. The
enclosure is factory set to deliver 40-55 fpm downflow velocity
measured 6" below the upper diffuser. The Class 5 HEPA-filtered
air flows across the work area and exits out the front of the
enclosure.
Data for the outflow exhaust volume, downflow velocities and outflow face velocities are listed for each Vertical Clean Bench model
below.

Chapter 3: Getting Started
Setting the Downflow Velocity
with the Speed Control
Adjustment
Adjustment of the speed control gives the correct downflow
velocity and is located behind the front panel. The downflow
velocity should be from 30-65 fpm for Class 100 (ISO class 5)
conditions. ISO Class 5 clean air conditions are maximized at a
setting within this range. The Vertical Clean Bench is factory set
at 40-55 fpm downflow velocity. (Consult your Safety Officer for
airflow recommendations for your application). Working at the
downflow velocity appropriate for the application will give the
quietest operation. Downflow velocity measurements are made
using an anemometer. An electric anemometer can be obtained
from your laboratory supply dealer. Downflow velocity
measurements should be taken 6" below the interior upper diffuser.
Using a small Phillips screwdriver, adjust the speed control to give
the required downflow velocity. See Figures 6-1 and 6-2 in
Chapter 6 to locate the speed control. The downflow velocity is
increased by turning the speed control counterclockwise and
clockwise to decrease downflow velocity.
2'
3'
Validating the Vertical Clean
Bench
To determine the actual downflow velocity, airflow velocity
readings are taken. This should be done 6" down from the top of
the interior upper diffuser. The “average downflow velocity” is
achieved by averaging the readings in the downflow test grid for
each model:
The downflow test grid consists of 9 test points, 3 points in 3 rows.
The back row of the grid is 6" from the rear of the work area. The
middle and front rows are 6.57" apart from the back to the front.
The first and last column of the downflow grid are spaced 6" in
from each sidewall with a center column spaced 5.32" away from
the first and last column.
The downflow test grid consists of 12 test points, 4 points in 3
rows. The back row of the 6" from the rear of the work area. The
middle and front rows are 6.57" apart from the back to the front.
The first and last column of the downflow grid are spaced 6" in
from each sidewall with two columns spaced 7.54" away from the
first and last column.

The downflow test grid consists of 15 test points, 5 points in 3
rows. The back row of the grid is 6" from the rear of the work area.
The middle and front rows are 6.57" apart from the back to the
front. The first and last column of the downflow grid are spaced 6"
in from each sidewall with three columns spaced 8.66" away from
the first and last column.
Refer to the exhaust specifications table in Chapter 2 for proper
airflow volumes and downflow velocities for your particular
model. A certified technician should complete validation.
The Purifier Vertical Clean Benches have been tested at Labconco
before shipment and provide ISO Class 5 clean air conditions
inside the enclosure. Labconco also performed extensive
performance testing to validate the clean benches for product
protection under ISO Class 5 conditions. For copies of these
validation reports, contact Labconco Customer Service.
Sealing the Vertical Clean Bench
to the Work Surface
When the Vertical Clean Bench has been set in place and wired, it
may be sealed at the work surface to prevent materials from
collecting under the walls. A bead of silicone sealant is
recommended to seal the Vertical Clean Bench to the work
surface.
