Half mask for respiratory protection Rd40 ST85
The ST85 is a half mask for professional respiratory protection, durable and decontaminable with a 40mm threaded front connector in compliance with the EN148-1 standard, compatible with all RD DIN40 filter cartridges on the market. It is ideal for the protection of operators handling harmful substances, paints, solvents and dusts.
The major advantage of the ST85 half mask is its ease of use. The quick-donning headgear keeps the mask comfortably in place.
