The base is made of special rubber compound, softer and more comfortable than ever. It is not affected by creams or lotions. The wide sealing frame and a deeper chin stop assure a snug, comfortable fit and a tight seal. The lens molded from impact resistant plastic / polycarbonate / is securely sandwiched between a groove in the face blank with a 2-part plastic lens ring.

The large field of vision is another safety feature of the mask. The connector is clamped into the face blank. It contains the threaded connection or the plug connection, the inhalation valve and the speech diaphragm. The speech diaphragm permits excellent communication. The exhalation valve is located in the lowest point of the face mask. Its large cross section results in a low exhalation resistance. Valve disc and valve cover are easily replaceable.

The harness enables quick donning and removal of the face mask without prior adjustment. A pressure - free fit is achieved also in combination with a protective helmet. With the carrying strap, the 3S can be carried in front of the chest, ready to use. Now, with the enlarged tabs of the face blank, the 3S harness is even easier to don. The inner mask provides an optimal air flow and keeps the lens free from fogging. It reduces the dead space effectively. The rolled edge cares for a soft and comfortable contact with the face.

The mask can be used with a single filter or can be connected to a breathing apparatus.
