In underwater diving, the purity of breathing air is a matter of life and death. Even trace amounts of carbon monoxide (CO) in compressed air systems can pose serious risks, as CO binds strongly with hemoglobin, reducing the body’s ability to transport oxygen. Ensuring safe, breathable air is therefore essential for divers, whether during professional deep-sea operations or recreational diving activities.
To address this challenge, DEAI CHEM’s Hopcalite Catalyst 12×20 mesh provides a proven and reliable solution for CO removal in SCUBA air purification systems.
Reliable Protection for Breathing Air Systems
Hopcalite Catalyst 12×20 mesh is a granular catalyst composed of manganese dioxide and copper oxide, specifically engineered to convert toxic carbon monoxide (CO) into carbon dioxide (CO₂) through catalytic oxidation. This reaction occurs efficiently at ambient temperatures in dry air environments, without requiring external energy input.
In SCUBA rebreathers and filling station air filters, the catalyst plays a critical role by eliminating CO contamination within compressed breathing air streams, ensuring diver safety under all operating conditions. Its performance stability and long service life make it ideal for both portable and stationary purification systems.
Advantages of Hopcalite Catalyst 12×20 Mesh
High catalytic efficiency: Converts CO into CO₂ quickly and completely, maintaining air purity within strict safety standards.
Room-temperature operation: No heating required, reducing system complexity and energy consumption.
Extended durability: Long operational lifespan under dry conditions, minimizing maintenance and replacement intervals.
Stable structure: Granular formulation ensures consistent airflow and low pressure drop in filtration units.
Mitigating Hidden Risks in Compressed Air Systems
While compressed air is vital in a wide range of applications — from firefighting to underwater exploration — it can also be a hidden source of CO contamination if not properly treated. DEAI CHEM’s Hopcalite Catalyst 12×20 mesh serves as a safeguard within these systems, providing reliable CO removal to protect users from exposure during high-risk operations.
