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.
