Description of Respirator 3M 7502 size M, 1 pc.
The half mask is made of silicone, which significantly reduces the risk of an allergic reaction and, among other things, increases the comfort of its use. The silicone obturator quickly takes the temperature of the skin of the face.
Bayonet type of attachment of 3M filters to the half mask Series 7500 is perfectly combined with 3M open and closed goggles and other PPE.
To determine the size of the half mask: 1) the width of the face is determined, for which the maximum horizontal width of the face along the zygomatic arches is measured - the bone arch located horizontally on the cheekbones to the outer ear; 2) the length of the face is determined, for which the vertical distance from the bottom of the chin to the deepest point on the bridge of the nose is measured. Sizes of half masks 3M series 7500: 7501-S small (face length 93.5–113.5 mm, face width 117.5–135.5 mm), 7502 - M medium (face length 103.5–123.5 mm, width face 126.5–144.5 mm), 7503 - L large (face length 113.5–133.5 mm, face width 135.5–153.5 mm).
