Technology Details
Reliable Connection to the Clean Air Source
The 4090.050 pressure hose is the basic supply line that carries clean compressed air from the external source to the regulator unit on the user's belt. Its standard construction is optimised for durability and resistance to the typical conditions of an industrial environment. The 10 metre length gives the welder a large working radius and freedom of movement around the workstation without having to keep moving the air source. It is a key element for an uninterrupted supply of breathing air. This component is an investment in mobility and continuous protection in hazardous zones.
Guaranteed Integrity of the Supplied Air System
A genuine Optrel pressure hose is essential for maintaining the full integrity and certification of the entire Supplied Air system. It is precisely matched to the couplings and pressure parameters of base systems such as Optrel 4090.000. This eliminates the risk of leaks, pressure drops or damage that could result from incompatible substitutes and put the user's health at risk. It ensures that the system works as the manufacturer intended and meets strict safety standards. Choosing the original hose is an investment in the certainty that your personal protection system will work flawlessly at the critical moment.
