HANDLING AND STORAGE OF FILTER ELEMENTS
Particulate filters include a wide range of filter types, sizes and
performance capabilities. These filters are designed to remove
airborne particulate from an air stream. Filters can consist of 30%
efficient (by ASHRAE Standard 52.1-1992) prefilters and up to
99.9995% efficient HEPA (high efficiency particulate air) filters. In
general, all particulate air filters are fragile and should be handled
with care. The following precautions should be observed upon
storing filters:
Store in a clean low humidity air controlled environment.
Filter should remain in its original shipping container with correct
orientation until put in use.
Temperature in storage area shall not be less than 0 °F or more
than 100 °F.
Stacking of filters is prohibited.
Moving of filters should be restricted – for fear that the media will
become damaged.
Shelf life is no more than three years for both gasket and gel seal
filters. (see manufacturer’s instructions)
All filter manufacturer’s instructions and warnings shall be
followed as well.
INSTALLATION OF NEW HOUSINGS

Position the housing adjacent to the ductwork. Housing should
be welded, bolted or gasketed permanently to the ductwork.
2.
Housing should be securely mounted to either a base or other
permanent edifice.
3.

removed and replaced.
4.
Following installation, ductwork and housing should be cleaned
to eliminate any and all contaminants as well as any other items,
which may have been stored in the unit during shipping.
5.
Install filter(s).
6.
Install PVC Bag(s) on Bagging Ring before door is installed.
7.
Perform designated leak test/DOP test (designated by either the
chief safety officer or engineer) to insure that the unit is working
properly and is not leaking.
