Active filters


The half-mask is equipped with two

ventilation openings that ensure low

exhalation resistance. The ventilation

openings are protected by covers that

effectively protect the membranes

against dust, mist and paint aerosols,

while the easily adjustable elastic

headbands are designed in a “V” shape

loop to allow for a firm and comfortable

attachment of the mask onto the back

of your head. It can be used as a filtration

device in combination with the SR 307

compressed air attachment, which then

serves as a breathing device that has

connections for a continuous supply of

compressed air. Included in the package

is 1 holder for the SR 5153 pre-filter, 1 SR

221 pre-filter, 1 cleaning cloth.
