Gas Masks and Their Different Types

Gas Masks

A gas mask (class 3 respiratory protection equipment) is personal protective equipment (class 3 respirator PPE). It's regulated by EN140 for half-mask respirators and EN136 for full-face respirators. Due to their large range of filters, RD DIN40 single-filter gas masks with universal 40mm filters are the most popular.

Half-mask respirator

The lower half of the respiratory protective mask covers the nose and mouth. The mask is made of a soft seal with an adjustable harness that protects the breathing tubes. Half mask respirators however presents two main usage restrictions:

– Substances that are to be filtered shall not cause irritation to the eyes such as chlorine, ammonia, derivatives, nitrous, sulfuric, or hydrochloric acid…

– Filtering cartridges should not exceed 300g. This limits the number of particles and gases that are combined in cartridges such as the ABEK2-P3 filtering carts

Full-face respirator

Full-face respirators, also known as panoramic respirators, offer users a wide field of vision up to 98%. They are lighter than half-mask respirators and provide complete protection for the eyes and breathing tracts, making them safer.

They can be fitted with filtering cartridges up to 300g, including complete particles or gas protective combinations such as ABEK2-P3 filters. These are the most commonly used cartridges in the industry.
