Logic Model Identification
The primary serial tag is on the lower outside edge of the right corner post.
The secondary serial tag is located on the front of the electronics module on the top right
side of the cabinet.
The first two digits of the serial number are the year of production; the next two are the
month. The next 5 digits are the sequence of production, and the letter following the
serial number is the revision level of the cabinet.
Downflow Test Specifications
All models are classified as uniform downflow.
All tests performed as described in ANSI/NSF Standard 49:2012.
UV Lamp, IV bar and all other accessories must be removed before measuring downflow.
Inflow Test Specifications
All tests performed as described in ANSI/NSF Standard 49:2012.
Secondary Inflow Test Specifications
Must use Labconco holder P/N 3836405 to perform this test properly.
1.
Use the appropriate template included in Certifier Kit# 3858403.
2.
Measured from the bottom edge of the probe holder to the center of the thermal
anemometer sensor element.
* - Locate the single row of holes at the front of the grille. Mark the 6
th
hole from the side wall
and subsequent test points every 9 holes until the number of test points marked equals the
width of the cabinet in feet (3-foot cabinet, mark the first 3 points). Repeat for the opposite
side.
HEPA Filter Leak Test Specifications
3.
Based on mineral oil.
4.
The actual aerosol concentration is what was observed during testing.
Aerosol generator should be placed in the left rear corner of the work area, pointing
toward the rear grille.
For uncontaminated units, the upstream concentration can be sampled from the tube
located under the work surface.
Metric calculation of concentration is:
# of Laskin nozzles @ 138K Pascals x 6.372/Volume of air in m
3
/sec. = Conc. In
ug/l
Exhaust Data
5.
Total Exhaust Volume. Cabinet air intake sealed shut and cabinet blower off.
6.
Measured as per ASHRAE methodology for measuring air volume in round ducts.
7.
Measured at the exhaust transition sampling point, relative to atmosphere.
Supply and Exhaust HEPA Filter Specifications
8.
Without gasket
Motor / Blower Specifications
9.
Each motor must be programmed by Labconco for the appropriate width cabinet. The
