Respinano FFP2 Anti Bacterial respiratory mask
Nanofibers with large surface area to volume ratio have shown great potential in
filtration applications, including air filtration, dust capture as well as absorbing
and detoxifying biological and chemical contaminants. Polymer nanofibers with polar
functional groups have strong affinity to particulate matter (PM) pollutants and
therefore show high removal efficiency at low pressure drop and high optical transparency.
Nanofibers are promising for use in face masks to achieve both high PM capture efficiency
and sufficient air permeability. The anti bacterial layer in respiratory mask is
very suitable for hospital invironments. The nanofiber layer traps the harmful bacterias
and the anti abcterial layer kills these bacterias. As it can be seen in the figure
below, the addition of nanofiber and anti abcterial layers increase the efficiency
of particle trapping and destroy the harmful bacterias and at the same time allows
the air to pass through, which in respiratory masks it is known as breathability.
According to BS EN 149:2001 standard for filtering half masks (also called filtering
face pieces). FNM Co. Ltd., can produce different classes of respiratory face masks
(FFP1,FFP2,FFP3). FFP2 Anti Bacterial respiratory mask with efficiency of 94% (for
0.3 micron particles) and pressure drop of 55 pascal is suitable for Hospitals and
mine contaminations, non toxic chemicals. The performances of FNM’s nanofiber-based
respiratory face masks can be seen in the fiqure below.
