| The
Flanders/CSC GRF-Series bag-in/bag-out filter housing allows for the
installation of a single radial-flow HEPA filter element in a low CFM
ventilation system (e.g. glovebox, isolator).
The GRF-Series filter housings are
designed for particulate filtration. The GRF-Series design allows
the housing to be tested in place and is flexible in that it allows
various arrangements of inlet and outlet ports to fit particular
applications.

One of the primary uses of HEPA filters
is for the containment of toxic materials. When filters become
contaminated in service with these materials, a method for their removal
without direct operator contact is necessary.
The bag-in/bag-out feature of the GRF-Series
allows the operator to change filters without coming into direct contact
with the toxic materials (such as viable organisms, radioactive dust,
and carcinogens) that have been collected by the filter element during
it's service life.
Air is supplied to and exhausted from the
GRF-Series housing through round inlets and outlets that are connected
to the owner's pipe or ducting. |

The GRF-Series housing is designed for
single filter replacement from the top of the unit. The housing
can be installed for top access or side access. The housing can be
supported in several ways, such as mounting lugs, stands, and even by
the inlet/outlet connections in some applications. |
