|
 Provides
an ISO-5/Class 100 (HEPA filters are 99.99% efficient
on .3 microns) vertical laminar airflow within the work
chamber, protecting product being handled from outside
contamination. The unit is stationary, allowing permanent
electric, gas and water services. Wet chemistry process
stations and isolated vibration-free tables under the module
are easily interchangeable. Individually tested and
certified to meet or exceed the specifications for Laminar
Flow Clean-Air Devices as per Institute of Environmental
Science IES-RP-CC-002-86. |
Filter
-
Three inch HEPA (High
Efficiency Particulate Air) type, aerosol challenged, zero
probed. Aluminum frame minipleat design, Minimum efficiency
of 99.99% at .3 microns.
Prefilter -
1" bonded polyfiber media
minimizes surface-loading. Quick-release aluminum frame.
Easily accessible from front of unit. 78 % arrestance –
56-57 ASHRAE.
Airflow -
Average measured clean air velocity 90
fpm (+/-10 fmp). All measured values within +/- 20%
uniformity.
Construction -
Woodboard construction for minimum
noise & vibration. White and blue plastic laminate finish.
Protects plastic egg crate diffuser screen in front of HEPA
filter maintain uniform air velocity within work area. Front
ambient intake through louvered aluminum grilles.
Front-loaded HEPA filters. Acrylic lining to 30" above floor
at rear and side walls. 2" sq. tube support frame (standard
"H" design) w/levelers. Frame bolts together (with guides
for head location).
Electrical & Power Requirements -
All electrical components are UL
Approved. Standard 15 Amp, 1 pH, 60 Hz. SJO power cord w/
3-prong ground plug.
NEC Electrical
Code
Motor/Blower Assembly -
High efficiency motors to reduce
electrical load. Motors are thermally protected &
self-lubricating. Motors/Blowers are selected to maintain
constant required airflow rate up to 2x the initial static
pressure.
Lighting -
Recessed 1 pin fluorescent
lighting. 125ft. candle +/- 20ft. candles.
Controls -
Solid state, adjustable airflow
control, 80-120 fpm, 15A max. load capacity, internally
mounted to prohibit accidental change. Illuminated switches
on face panel for motor & lights.
