CTEK Diamond Contaminated Diving Helmet
Product details
Dual-Mode Exhaust Flexibility: Unique modular design allows the diver to operate in either surface exhaust (surface vent) or ambient water exhaust (open circuit) modes.
Contaminated Water Protection: In surface vent mode, exhaled gas is sent to the surface rather than the surrounding water, ensuring a cleaner environment for the diver—ideal for working in biological or chemical contamination.
Rugged Stainless Steel Shell: Features a durable stainless steel helmet shell that requires no refinishing if the surface is scratched or gouged, significantly reducing long-term maintenance.
Reclaim System Ready: Exhaled gas in surface vent mode can be directed to a reclaim system or simply vented to the atmosphere on deck.
Simplified Maintenance: Innovative design eliminates threaded inserts for securing the port retainer to the shell, enhancing durability and ease of service.
High-Performance Breathing: Features an integrated inhalation body and pod unit based on the high-performance CTEK 455 Balanced Regulator.
CTEK Diamond Contaminated Diving Helmet
The CTEK Diamond represents the next evolution in modular stainless steel diving helmets. Designed for versatility and extreme durability, it allows divers to switch between "Surface Vent Mode" and "Open Circuit Mode" via a simple two-step process before entering the water.
This capability makes it the premier choice for diving in contaminated waters where exhaled bubbles must be kept away from the face port or containment is required. Built with a robust stainless steel shell that withstands harsh conditions without the need for refinishing, the CTEK Diamond meets the rigorous standards established by Dive Lab and is Commercially Rated (CR) for professional use.
