Unvented chemical goggles for gas and vapour

Fully sealed goggles for gases, vapours and chemical splash.

Goggles with no vents at all, which is what the field-of-use mark 5 (gas and fine dust) requires alongside 3 (liquids). Synthetic-rubber frame resists acids and solvents, and the polycarbonate lens carries a premium anti-fog coating because without ventilation condensation is the main challenge. Wide neoprene strap for long wear. For water treatment, hazardous-waste handling and acid transfer.
