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 or three 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.

With the Proflow3, always use 3 filters of the same type and class.
o
Display and alarm buzzer.
o
Rechargeable NiMH battery 9,6V/standard or power. Battery can be recharged 400-500 times.
