1. Filter respirator: Filter respirator is an easy-to-use respirator based on filtration. The filter element (filter screen) of respirator can filter out solid particles, liquids and simple harmful substances in the air, but it can't filter out oxygen.
Air respirator: Self-oxygen respirator is a kind of respirator that provides fresh air by compressing oxygen cylinders. This respirator consists of an oxygen tank and a mask or mask, which can provide self-oxygen supply for up to 30 minutes.
3. Oxygen respirator: This respirator is a respirator equipped with a pneumatic bottle, which can provide a self-sufficient gas source for a long time, so that firefighters can breathe fresh air in toxic gas, smoke and other environments.
Isolated gas masks are often used to isolate the wearer's respiratory system from the air in the working environment. The mask itself provides oxygen or protects people from the invasion of clean environment to maintain normal breathing of the human body. Suitable for occasions with low oxygen content and high toxic concentration in the air.
There are self-contained respirators (divided into oxygen respirators, chemical oxygen respirators and air respirator) and hose respirators (divided into white-suction respirators or air-supply respirators), which are used to rescue poisoned personnel and life-threatening workplaces with unknown site conditions. Therefore, it is very important to train users and correctly select anti-virus equipment.
