Huish, the company that owns the premium Atomic brand, bought AUP's Oceanic and Hollis brands last year. Among the inventory were Oceanic regulators with diaphragm first-stages including the CDX, EDX, FDX10, and FDXi, plus Hollis regulators with diaphragm first-stage types DC7, DC3, DC1, DC2,
and DCX.
Now, a serious problem has been discovered, and Huish has issued a voluntary recall.
If you have any of these models purchased since October 1, 2017, don't use them and return them to your dealer for an upgrade.
Furthermore, if you have any of these models and had it serviced between October 2017 and May 2018, it, too, should not be used and returned to your dealer for an upgrade.
A source within Huish told Undercurrent, the company employed a new high-pressure valve seat made of a similar material used in Atomic regulators, but when tested on an ANSTI machine, they discovered that in certain cases it severely restricted airflow when tank pressure dropped below 500 psi (35bar). That part needs to be replaced by an alternative modified-design balance-pin.
Huish ways they have not heard of any user suffering any ill effect, although the U.S. Consumer Product Safety Commission announcement says there is "a risk of drowning."
