Can positive pressure respirator use half mask ？
Previously, we introduced the composition of positive pressure air respirator, which is mainly composed of mask, air supply valve, pressure reducer, gas cylinder and back plate. The mask is the most closely connected part with the user. The mask of positive pressure air respirator is designed as a full mask, so can the air respirator be used with a half mask? Today Cangzhou Haigu will answer this question.
Can the positive pressure air respirator be used with a half mask? The answer is no, because the half mask directly covers the mouth and nose of the user, and there is not much air storage space. If the half mask is connected with the air supply valve of the air respirator, the air will continuously flow into the half mask, and the excessive air flow will affect the normal breathing of the user. The full mask has a face screen, which can hold the air and keep the pressure inside the mask higher than the external pressure, which can't be achieved by half mask.
In addition, the positive pressure air respirator is generally used in the environment with high concentration of toxic gas, which may cause damage to the face. The full face mask can cover the face, while the half face mask does not have the coverage area as large as the full face mask. Therefore, the half face mask is not suitable for use with the positive pressure air respirator.
Through the above answers, I believe you have a certain understanding of whether the positive pressure air respirator can use the half mask, and hope the answer can help you.
