These
replacement filters are of the highest quality. They are
all easily replaced by using simple hand tools (two Crescent
wrenches) and a suitable receptacle such as a plastic bag
to place to old filter in. For more information about how
to replace the filters, please see the Safe Cell manual.
All
of these filters come with the Safe
Cell:
Pre-filters
The pre-filters are designed to extend the life of the HEPA
filter by trapping both large and small particles. The first
filter is the roughing filter with an average efficiency
of 25 to 30 percent when tested in accordance with ASHRAE
52.1. The roughing filter extends the life of the intermediate
filter or pre-filter and reduces its change frequency. The
second filter is the intermediate filter with an average
efficiency of 80 to 85 percent when tested in accordance
with ASHRAE 52.1.
The
HEPA filter
The nuclear grade HEPA filter is a special filter we have
made just for our application.Each HEPA filter is individually
tested to MIL-STD-282 before it leaves the factory, your
assurance that it meets rated efficiency. The penetration
and actual airflow rate are indicated on the label. Each
filter is also assigned an individual serial number.
Every
HEPA filter is individually DOP tested: This has been the
industry standard test method for many years. It is conducted
using a forward light scattering photometer. The HEPA is
challenged with 0.3 micrometer particles of dioctyl-phthalate
(DOP). By measuring the upstream and downstream concentration
of these particles, the HEPA filter cell efficiency can
be calculated.
Underwriters
Laboratories Classification UL 586: This classification
to insure that each HEPA filter cell is individually
tested at the factory. Additionally, representative
HEPA filter cells are tested by UL to ensure that they provide
their rated HEPA level filtration, after being subjected
to the following conditions of a high moisture environment
of (90% R.H.), a high temperature environment of (371 deg/C),
low temperature environment of (-3 deg/C). UL also subjects
the HEPA filter cell to a spot flame test of (954 deg/C).

Carbon
adsorber
The nuclear grade war gas adsorber is a block sieve adsorption
filter cell consisting of two containment medias and a center
block of blended granual nuclear grade war gas carbon and
ASZM-TEDA.
This
special blend of two kinds of activated carbon adsorbs warfare
gases and radioactive iodine in order to meet the requirements
of US Army Corps of Engineers ETL
1110-3-498 standard for war gas removal.
