We have introduced the composition of a positive pressure air respirator, which is mainly composed of a mask, air supply valve, pressure reducer, gas cylinder back plate. The mask is the most closely connected part with the user, positive pressure air breathing The air respirator is designed for full face mask, so can the air respirator be used with half face mask? Today, Dongguan Shengyao Plastic Products Co., Ltd.-a manufacturer of protective masks will answer this question.

      Can a positive pressure air respirator be used with a half-mask? The answer is no, because: the half-mask directly covers the user’s nose mouth, there is much space for air storage. If the half-mask is connected to the supply of the air respirator After the air valve, air will continue to pour into the half-mask. Excessive airflow will affect the user’s normal breathing. The full-face mask has a face screen that can hold part of the air keep the pressure inside the mask stronger than the external pressure. The half mask cannot be reached.

       In addition, positive pressure air respirators are generally used in environments with high concentrations of poisonous gas. The poisonous gas may cause damage to the face. A full-face mask can cover a person's face, while a half-face mask does cover a large area as a full-face mask. The mask is suitable for use with positive pressure air breathing apparatus.

       Through the above answers, I believe that everyone has a certain understanding of whether a positive pressure air respirator can use a half-mask, I hope it can help you.
