3. Technical information
o The complete blower unit consists of a blower body, a blower, a breathing hose, a belt, a battery,
and a recharger.
Two thread filters must be attached to the blower device. The connection thread of the filters and the
breathing hose of the blower device conforms to the standard EN 148-1.
With the Proflow2, always use 2 filters of the same type and class.
o Display and alarm buzzer.
o Rechargeable NiMH battery 9,6V/power. Battery can be recharged 400-500 times.
o Accessory: Instead of the battery, one can use a power supply (230 VAC), or a lighter socket cable
(12 VDC) for vehicles. In case the optional power supplies are used, the battery (snap coupling)
must be detached.
Automatic regulation of the

*) This can be achieved with a clean filter and a good battery.
Particle filter + Sari or Promask = 7 h
Particle filter + Vision = 6 h

do not provide sufficient protection in case of
breakdown or inferior output of the blower.
Therefore, devices of class TH1 must never be
used against carcinogenic, very poisonous or
radioactive gases and vapours.
Device with combined filter
The specified multiples of threshold value for the gas or particle filters
are given separately, but in all cases the lowest value applies.

TM2 gas filter class 1, 2 or 3

For devices with combined filter apply the
relevant limitations of gas and particle filters.
*) Provided that the maximum permissible detrimental gas concentration for the gas filter is not exceeded. For
power-assisted filtering devices with gas filter, concentration must not exceed 0.05 vol.% in gas filter class 1 and
0.1 vol.% in gas filter class 2 and 0.5 vol.% in gas filter class 3.
**) If national guidelines exist: in all cases the lowest value applies.
