Optrel face seal for clearmaxx PAPR helmet (4156.010)
Genuine Optrel face seal made for the PAPR version of the clearmaxx grinding helmet. It is a key certified component needed to keep the e3000X air supply system intact and at the TH3 protection class. Designed for an exact fit and a tight seal, it ensures that only filtered, clean air reaches your breathing zone. Replacing this part is a basic step for continued safety and comfort in dusty environments.

Technology in detail
Positive pressure and TH3 protection
The face seal is a critical engineering element that forms a closed barrier between the inside of the helmet and the surroundings. Its precisely designed shape and flexible, flame-retardant material sit tightly on your face. This tightness allows the e3000X air supply system to build and hold constant positive pressure inside the helmet shell. The positive pressure actively stops contaminants, fumes and dust from entering the breathing zone, which is the basis of TH3 certification. A genuine, undamaged seal is a direct investment in the highest class of health protection.
Optimised airflow and cooling effect
The seal does more than isolate: it works with the internal air channels of the clearmaxx helmet to manage the flow of clean air. It acts as a deflector that guides the air delivered by the e3000X unit evenly and in a controlled way. The air flows over the face and forehead, giving a noticeable cooling effect and preventing the visor from fogging, without irritating the eyes. This close integration is only possible with dedicated components. It adds safety and noticeably improves comfort during long, intensive work.
A key part of the Optrel e3000X system
The e3000X respiratory protection system is designed as a closed, highly integrated system in which every part has a defined role. The face seal is the necessary link that lets the filter unit deliver its full performance and protection. Without the tight seal this component provides, the system could not reach and hold the parameters required for TH3, and its effectiveness would drop sharply. Regular inspection and replacement of the seal is therefore a key maintenance task that keeps the whole system working as one certified unit.
