World's
first Breath-Synchronized Air Flow System (BSFS)
|
|
|
BSFS
continuously supplies equivalent amount of breathed air
with the wearer. By monitoring inside pressure of the wearer's
facepiece that varies according to the wearer's breathing
pattern, BSFS calculates necessary air flow rate for smooth
and comfortable breathing. Then it controls fan speed so
that inside pressure of facepiece is kept consistent while
inhalation and exhalation.
Unlike conventional PAPR systems, which simply keep sending constant
and large amount of air flow, BSFS supplies an optimum amount of
air flow that is synchronized with the wearer's inhalation pattern
and also it keeps positive pressure inside the facepiece. This assures
a considerably longer service life of filters and batteries than
a constant flow powered air-purifying respirators.
Full-Facepiece PAPR, with a Built-in Moter Fan Type, is also available. |

| BL-50 supplies equivalent
am ount of inhaled air
into facepiece. The air blow is activated when
inhalation begins. No air is supplied into the
facepiece during exhalation. Thus, natural
breathing is available and you will feel as if there
were no respirator on your face. |

Enhanced ability
to maintain safety |
|
BSFS blows optimum amount
of air that is synchronized with wearer’s inhalation
pattern.
By monitoring air pressure in facepiece that varies according
to the wearer's breathing pattern, BSFS calculates
necessary airflow rate for smooth and comfortable breathing.
As the internal air pressure is kept consistent, chances
of inward leakage are very slim. As shown in the above chart
(right), air pressure in facepiece becomes lower when
filter is clogged. (“FAN OFF” shows same condition
of ordinary respirator with clogged filter.) Then, there are
higher
possibilities of breathing difficulty and inward leakage. Even
under such conditions, BL-50 minimizes air pressure
reduction to lessen inward leakage. Thus, protection of wearer
is maintained in high level. |

Extended intervals
for
filter replacement |
 |
Breathing through particulate respirator
becomes difficult when filter air-flow resistance
reaches at 100Pa, which suggests replacing
filter. At filter resistance 100Pa, air pressure in
facepiece exceeds 200Pa, and wearer
experiences difficulty in breathing.
However, BL-50 keeps optimum facepiece air
pressure by supplying breath synchronized air
flow even when filter’s air-flow resistance
reaches at 100Pa.
This extends intervals for filter replacement and
saves running costs. |

Built-in
Motor Fan Type Model BL-50 |
 |
Intelligent motor fan is housed in facepiece to
achieve quicker response to feed back signals
from breath sensor.
Respirator and motor fan
are integrated in one body to make the
system compact. |
