The FSBQ-I filter elements are designed for use in the FSBQL
duct filters. The design of this filter element is very simple: the
filter element mat is sewn over a steel wire frame. The FSBQ-I
filter elements are available in filtration classes EU3 and EU5.
The filter elements can be fabricated on request with an
activated carbon mat rated at EU4.
All filter elements are wrapped in protective plastic film which
must be removed before installation.
