Protective Half Mask, without Filters, Blue

Product details

The DUO half mask is a professional, durable and decontaminable mask intended for use in industrial and technical applications. It is designed for handling hazardous chemicals, toxic gases, solvents, dust and for spray painting. It is suitable for use in chemical and pharmaceutical companies, agriculture and mineral grinding processes.

The DUO half mask is used exclusively in combination with Spasciani 2000 series filter cartridges, fitted with a snap-in connection system. The filter cartridges can be used together with special pre-filters, which protect the filter element against accelerated clogging in environments with high dust levels. The mask does not come with filters included; they are purchased separately.
