The full face mask product is made of gray silicone, with a black screen frame and front grille. The screen has a wide field of view, and the interface is equipped with a sound film to improve sound transmission. The mouth and nose mask inside the mask is designed to reduce the amount of fog and CO2. The "5-point" headband can be quickly relaxed/fastened, and the tightening buckle on both sides and the front can adjust the tightening strap to adapt to different head shapes, with * sealing.
This mask can be slightly improved to be used in conjunction with self-contained breathing apparatus that comply with European standards EN137 or GA124-2004.
The face mask is similar to the previous example, but the screen frame and front grille are blue.
This mask can be used in conjunction with an aerodynamic breathing device. It can also be used in conjunction with helmets and eyeglass frames.
Correct wearing method of face mask
1. Place the eyepiece of the face mask facing downwards and put on the neck strap.
2. Insert the mask into the chin and tighten the head with a headband.
3. Extend the headband as much as possible to cover the back of the head.
4. Adjust the tightening band from top to bottom to tighten it.
5. Block the interface of the face mask with the palm of your hand, inhale and hold your breath. The user feels the mask tightly against their face until they resume breathing. This method can test the sealing of the face mask. If you feel that the mask is not close to your face, adjust the tightening strap and repeat the experiment.
