I - FUNCTION AND DESCRIPTION OF THE ChemoSHIELD

The ChemoSHIELD
®
is a negative pressure isolator offering product, personnel & environment protection
from hazardous or potent pharmaceutical compounds and chemotherapy agents. It features vertical laminar
airflow and a closed front viewscreen. Other uses for the cabinet include formulation, mixing of hazardous
non-explosive chemical compounds and other applications that require Class 100 (ISO Class 5) air.
ChemoSHIELD Airflow and Base Features
The ChemoSHIELD
®
cabinet is designed to provide vertical laminar airflow within the work chamber
(See Fig. 1). The stainless steel metal diffuser just below the downflow HEPA filter creates gentle laminar
airflow over the work zone and an air curtain at the viewscreen. The air pressure is negative in the work
zone to insure maximum personnel protection while the sealed work chamber and HEPA filtered airflow
provides product protection.

The pass-through chamber allows operators to introduce or remove items from the main work chamber
while maintaining the internal aseptic conditions. The stainless steel metal diffuser just below the downflow
HEPA filter creates laminar airflow in the chamber and air curtains at the viewscreen and tunnel connecting
the two chambers. The air pressure is negative to insure maximum personnel protection.
Airflow within the tunnel connecting the two chambers is slightly turbulent due to the pass-through air
curtain. This helps purge the tunnel.
Airflow within the work and pass-through chambers is pulled through exhaust HEPA filters located under
the work surfaces into a common exhaust plenum. The air is then exhausted out of the cabinet through the
building exhaust system.
