Bag Filter
Bag filters are generally deep in the
direction of air flow, which helps reduce
pressure drop and handle higher
loading over a wide range of efficiencies.
Bag media may consist of micro
fiberglass, polyester or other synthetic
fibers. In Trion products, bags are
successfully used in multi-stage filtration
to prolong main filter life, which in turn
reduces maintenance costs.
HEPA Filter
High Efficiency Particulate Air (HEPA) fil-
ters are 99.97% efficient in removing par-
ticles 0.3 micron and larger. HEPA filters
utilize spun-hooked glass fiber rolled into
a paper-like material. This material is
pleated to increase the fiber surface area
and bonded (or potted) into a frame. Hot
melt is used to hold the pleats far enough
apart to allow air to flow between them.
The life of a HEPA filter depends on the
ambient conditions and maintenance of
the pre-filters. Since airflow capacity de-
creases and static pressure increases over
time, HEPA filters actually become more
efficient as the filter loads.
