Supreme™ and Dry™ First Stage Environmental Protection

For diving in cold water conditions, or commercial diving in

contaminated water, Aqua Lung offers two different types of

environmental first stage protection kits which seal the ambient

chamber from the environment. This helps to prevent ice from

forming inside the first stage ambient chamber, and effectively

extends the life of the first stage diaphragm for regulators used

in extremely polluted or contaminated water.

The Supreme™ environmental protection kit contains sili-

cone fluid, which fills the ambient chamber and acts as a trans-

fer medium between the diaphragm and the surrounding water.

The Dry™ kit also seals off the ambient chamber, but incorpo-

rates a specially designed piston to transfer the surrounding

water pressure to the diaphragm, instead of silicone fluid.

This environmental protection comes with those regulators

which are sold specifically for cold water use, or it can be in-

stalled as an add-on option by your Authorized Aqua Lung

Dealer, provided that your regulator has a balanced diaphragm

design first stage.

For more information on diving in cold water, read the sec-

tion titled Cold Water Diving, on page 20.
