Specifications Details
Designed as
an exhausting vertical laminar
airflow
clean workstation, it is to be used when toxic odors & fumes
are present. Intake air passes through a HEPA filter (99.99%
efficient on .3 microns) providing a Class 100 airflow into
the work chamber, and downward through the perforated work
surface. It is then exhausted through the internal wall duct
for discharge at the top of the unit. A remote exhaust air
system is required to balance the work chamber's airflow
pattern. The use of polypropylene offers immunity to
corrosion, resistance to acids and solvents, non-conductive
properties, and a minimum of maintenance. Unit is complete
with storage space. Individually tested & certified to meet
or exceed the specifications for Laminar F Flow Clean Air
devices as per institute of Environmental Science -
IES-RP-CC-002-86.
