The unit can still be used if the batteries are fully depleted, but it reverts to a standard negative pressure system. Switch the blower on, and the unit instantly provides 90 liters/min of airflow drawn through the attached filters.Īs a result, you'll have an easier time breathing, maneuvering, and doing practically anything with your gas mask. Then, the hose connects directly to your mask, reducing your mask's overall weight for improved mobility. Weighing just 1.8lb on its own, our PAPR straps to your belt and uses two 40mm CBRN filters. The design of our new powered air-purifying respirator addresses all of those issues. Not to mention, the added weight of strapping filters to your face can make wearing a gas mask cumbersome over time. It can be distracting, but worse still-not everyone has the lung power to use a negative pressure gas mask.Ĭhildren, those with respiratory issues, or anyone who can't blow up a large balloon can't use most gas masks. Filters increase breathing resistance, and any negative pressure gas mask will cause you to tire faster than you would without one. That sounds simple, but in practice, it's not always so easy. With any standard gas mask, including our MIRA Safety CM-6M and CM-7M, your lung power pulls air through the filter that removes toxins and potential threats.
