  • No fit testing is required.
  • Excellent hood stability and fit support a range of operations.
  • The skirting system fully inflates.

The Onyx-45 blower is compact, easy to carry, and extremely reliable, supplying a constant air supply that maintains positive pressure into NBC protective masks.

The Onyx blower draws filtered air from the NBC filter attached to it and supplies the air via a flexible hose directly into the NBC protective hood / mask.

The blower creates overpressure within the interior of the mask, thus preventing the entry of chemical and biological warfare agents.

Made of polycarbonate, the blower is fitted with loops for suspension from a belt or a back harness; this arrangement provides maximum convenience even under field conditions. The advanced & enhanced “45- Onyx” blowers are designed for personnel engaged in strenuous activity. The blowers make it easy to breathe and enhance the comfort of using a standard rubber mask. The blowers are equipped with a monitor lamp so that users can verify their proper operation at all times. The “Onyx-45” blower fits all types of personal filter canisters with a standard NATO thread (40mm X 1/7”).

The Onyx-45 blower flow via an SPG P3 R filter supplies approximately 40 liters of air per minute with a resistance of 26 mm – 20 mm of water (depending on whether the blower is running in high or low mode) and is powered to work approximately 20  hours of continual operation.


  • Weight (including battery): Up to 500 gr.
  • Power supply: 1 lithium-sulfur or dioxide battery.
  • Operating voltage: 5.4 volts.
  • Airflow: approximately /min with a resistance of 26 – 20 mm of water.
