Since June 2001, the European Standard for particulate respirators
has be changed from EN149:1991 to EN149:2001. The major change
in EN149:2001 is that all particulate respirator will have
to provide protection against solid (non-oil) and liquid (oil)
aerosols. That is, the S (solid) class and SL (solid and liquid)
class have been combined into three categories only - FFP1,
FFP2 and FFP3. Your selection will be easier because each
respirator covers a wider range of applications.
San Huei obtained EN149:2001 through the notified body BSI
(CE 0086) in July 2001 and the new products cover the full
range of EN149:2001 - FFP1, FFP2 and FFP3. It is our best
intention to provide the up-to-date quality products for our
customers.
How to identify if your respirator meets the latest EN149:2001
standard? All EN149:2001 certified respirators will bear the
marking of EN149:2001 while the previously certified respirators
will bear the marking of EN149 only. |

ACMB is the abbreviation of Active Carbon Melt-Blown
which is loaded with heavy-duty charcoal, flexible,
soft, and very efficient against organic vapors and
bad odors.
Usually, the charcoal pre-filter is proceeded by mixing
charcoal and resin. So the charcoal
can be fixed still on the polyester fiber with the glue
of resin. However, the resin will close the
pore of the surface of the charcoal. Then,
the adsorption ability of charcoal will be decreased
seriously.

San Huei utilizes the technology
of protruding the melt-blown fibers to develop the resin-free
ACMB. Our ACMB is to mix the charcoal particles with
the melt-blown fibers. The charcoal particles have point
contact with the melt-blown instead of the
resin. Therefore, its adsorption ability will not be
decreased by the resin. And we can load heavy-duty charcoal
to achieve an excellent performance. The ACMB Comparison
Test proves that the ACMB pre-filter can achieve 6~20
times better than the traditional charcoal
pre-filter. Special treatment for acid gas is also optional.
Primary Competitive Advantage :
1. Excellent adsorption ability against organic vapors
and bad odors.
2. Soft, flexible, and comfortable. |
