Free Flow Control
This unit should be for Technical use only -
Regulators not designed for cold water use are especially prone to freezing. In the event of second stage freezing, free-flow can cause catastrophic loss of air. With the FCD fitted to your regulator, a simple sliding action allows the diver to isolate the free-flowing second stage and continue the dive using a secondary air source or alternatively, the diver can manually control the air flow allowing a safe ascent to the surface.
At Puffin Dive Centre we recommend solving the solution to free flow further up this problematic line - If your regulator is prone to free flowing in may be needing a service or upgrading to match the performance requirements needed for the activity used.
If you are unsure about why your regulator free flows - Please call us and discuss options before purchasing this product.
