Description

Cejn Breathable Air Couplings are designed to meet critical safety and performance requirements in sectors where breathable air is essential. With a long tradition of quality and innovation, Cejn provides robust and reliable solutions to ensure operator safety in environments such as rescue operations, underwater work, and industrial and firefighting contexts.

Superior Performance and Unmatched Safety

Cejn breathable air couplings feature exceptional flow capacity, a variety of connection options, and ease of use, reducing the risk of operational errors. The product line includes couplings and nipples designed to perform efficiently even at high pressures, up to 35 bar (508 PSI), delivering continuous airflow up to 3950 l/min (140 CFM), depending on the model. These couplings and nipples are specifically designed to provide secure connections and prevent accidental disconnections thanks to the automatic locking function.

Materials and Durability

Cejn Breathable Air Couplings are made from high-quality materials, such as nickel-plated brass and stainless steel, ensuring optimal resistance to corrosion and wear. NBR (Nitrile Butadiene Rubber) seals ensure airtight connections, maintaining the integrity of the breathable air supply system even in demanding environments.

Ease of Use

Cejn devices are designed for quick and secure one-handed connections, facilitating operation even in emergency conditions. The compact shape of the couplings minimizes required space, optimizing ergonomics and improving operational efficiency. The robust and lightweight design ensures the couplings are not only easy to use but also extremely durable, minimizing the risk of failure and providing years of trouble-free service.

Ideal Applications

Cejn Breathable Air Couplings are the ideal choice for a wide range of applications requiring high-quality breathable air, including:

  • Industrial sectors: for welding, painting, and other high-risk operations.

  • Safety and rescue: for use in rescue, firefighting, and ventilation systems.

  • Underwater activities: to ensure a safe and continuous airflow at high depths.

  • Protective operations: for hazardous environments where breathable air is essential.
