Working time: 7 hours. Charger Voltage: 110 V / 220 V. Air supply flow rate: First gear: 62 L/min Second gear: 74 L/min. Net weight of the air pump : 0.6 kg. 1 x air pump. 1 x full face mask. 2 x air pipe. 2 x canister filter. 1 x recharger. Before using the air supply fan, ensure that there is sufficient power and that it is operating normally. Before use, check all connections to ensure they are secure to prevent air leakage that may pose a health hazard to the user. Insert the appropriate length of the hose into the buckle on the safety belt at one end of the face mask.

Men should shave their beards before wearing the mask to ensure a proper seal. The long hose mask should be stored by designated personnel and inspected regularly. Any issues discovered should be promptly repaired, and damaged components should be replaced as needed. If you detect any unusual odors or a lack of airflow during normal use, please check or replace the filter consumables promptly. When the following situations occur, work should be immediately stopped, and personnel should evacuate the site. Drowsiness due to harmful gases. Detection of the odor of harmful gases. Irritation of the eyes, nose, mouth, or other areas due to harmful gases. Abnormal air flow or cessation of air supply. Shutdown due to power outage, malfunction, or other reasons. This equipment is suitable for various dusty workplaces and is effective in preventing various particulate matter dust, mist, smoke, etc. And odors below permissible levels. It is not suitable for oxygen-deficient working environments (air environments with oxygen levels below 18%), IDLH concentrations (immediately dangerous to life and health), or workplaces where explosive conditions may occur.
