SGE 400/3 BB CBRN Gas Mask Details

SGE 400/3 BB CBRN Gas Mask

Gas Mask Type

This SGE 400/3 BB CBRN gas mask is a NIOSH-approved CBRN gas mask. When used in conjunction with NATO 40mm CBRN filters, this full face type of gas mask is able to be worn in chemical, biological, radioactive and nuclear environments and provide a decontaminated face seal and filtered air supply to the wearer. With the butyl rubber face seal this mask has been proven to be worn for up to six days without having to be removed.



The crucial part of any CBRN gas mask is the facepiece, how it is made, and what materials are used. The SGE 400/3 BB facepiece is made of butyl silicone rubber. This is different to the SGE predecessor, the SGE 400/3, which only uses a silicone face seal which did not comply with NIOSH-approved CBRN requirements.

The facepiece of the SGE is what forms the mold for the following components: face seal, chin cup, head harness tabs, the wide vision eye lens, three filter assemblies and a receptacle for the drinking attachment.

The facepiece has buckles on its exterior which allows the supporting head harness to have a number of strong points of contact.



The nosecup is of the SGE is designed to be comfortable and effective as it is a crucial part of the system. The oral-nasal area of the mask is made of soft medical-grade silicone rubber which is designed specifically to come in contact with the body and not cause any irritation or discomfort against the skin.

Head Harness

Head Harness

The SGE 400/3 BB uses elasticized NBR rubber straps for its head harness system. These are attached to the back in a single unit. The cheek and temple straps, as mentioned above, are fastened to the buckles on the facepiece system. The pull points on the harness are located closer to the face of the mask to act tighteners when pulled together.

Front Module

Front Module

The SGE’s front module consists of protective face shield coating to protect the SGE’s internal components. The visor uses a polycarbonate material which is both highly scratchproof and chemical proof in its creation and has been tested to withstand projectiles. The front housing also contains the port for the drinking attachment system, outlet valves, and three NATO 40mm filter attachments.

The gas mask’s front module is the primary working space for the air ventilation valves. The exhalation valve uses a structure that covers the whole filtration membrane while still allowing the easy exhalation of air out of the mask, rather than having some of the exhaled air spread through the mask causing fogging.

Drinking system

Drinking system

The SGE 400/3 BB  incorporates a drinking system into the main body and the front module of the mask. The internal drinking device is an optional accessory that can easily be assembled in the bottom of the mask.



The SGE 400/3 BB uses 40mm NATO filters to provide respiratory protection against gases, vapors, and particles, in conjunction with the SGE gas mask. The SGE 400/3 has three filter ports on the mask, being in the middle, as well as the left and right cheek of the gas mask.

About The SGE 400/3 BB CBRN Gas Mask

SGE 400/3 BB CBRN Gas Mask

Medical, SCUBA and military safety provider Mestel Safety previously had the SGE 400/3 gas mask as one of the world’s competitive top selling gas masks due to its wide visibility, comfort, and affordability. To comply with CBRN requirements they introduced a butyl-rubber face-seal allowing it to withstand CBRN environments.

This SGE has the benefit of coming from a long line of gas masks, which means that it has been perfected with improved functions and industry specifications over time. For instance, it has three NATO 40mm filter ports, has a mouthpiece drinking assembly, and has full vision capacity. The visor itself is made of durable polycarbonate and has been tested to resist a one-inch steel ball at 335 miles per hour without inflicting any damage on the visor. To stop the visor from fogging up, the mask has a moisture release valve to help with any situations where it may be used for extensive periods.
