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.
