Chapter 3: Getting Started
Connecting the Protector
Radioisotope Hood Exhaust
System
The stainless steel exhaust
connection should be installed by a
qualified HVAC contractor.
The exhaust connection on your hood
has been designed for 11" nominal pipe
(11.00" OD) to allow for minimum static
pressure loss with proper transport
velocities away from the hood. Consult
Labconco Customer Service should you
require help sizing your blower for the
exhaust volume and total system static
pressure loss.
The selected exhaust duct material must
be fabricated out of type 304 stainless
steel, or type 1 unplasticized polyvinyl
chloride (PVC) material. The duct
should be fully welded in the case of the
stainless steel material or solvent bonded
in the case of (PVC) so that it does not
feature any cracks or holes to allow for
the collection of radiochemicals.
Connecting to the Optional
Filter Packs
Both HEPA (High Efficiency Particulate Air) and
activated carbon filter pack assemblies are available for
use with the Protector Radioisotope Hood. Please
contact your local EPA or NRC office for

WARNING: The weight of the stainless steel
exhaust ductwork system must be supported
independently of the hood superstructure. Do
