The 3M 9915 offers lightweight, comfortable respiratory protection against dusts, mists and nuisance‑level acid gases such as hydrogen fluoride, sulphur dioxide and chlorine. Its twin‑strap design, foam nose seal and aluminium noseclip give a good face seal, while the off‑the‑face design provides low breathing resistance.
Fitting instructions are included: place the elastic straps over the head, mould the metal nosepiece to the nose, and check the fit by exhaling vigorously. The respirator must be used in well‑ventilated areas, is maintenance‑free under COSHH regulations, and is colour‑coded dark blue for easy identification.
