ION

Breathe Easy.

Smallest Second Stage Ever

The ION LT is AERIS' smallest and most streamlined second stage ever with an outer ring diameter of only 2.3" and 5.4 ounce weight. The ION LT's second stage is made from an ABS/Polycarbonate composite blend of materials making the ION LT both extremely rugged and lightweight, reducing jaw fatigue on extended dives. The extremely lightweight cover ring is machined from a solid piece of aircraft aluminum, and then hard anodized to prevent corrosion. 

Patented Dynamic Adjustment

A common objection to typical adjustable second stages is that divers can't imagine themselves twisting and turning a knob as they descend and ascend through the depths. If inhalation resistance is set near zero at depth, your ascent would require you to manually increase resistance as ambient water pressure is reduced to prevent free-flow. The ION LT features a pneumatically balanced valve that maintains a preferred breathing resistance throughout the dive. Set it once and the ION LTautomatically adjusts to make breathing as easy at 100 feet as it is at 30 feet. 

MaxFlex Hose

Ever notice that nearly every picture you see of a diver, their regulator looks like it’s not the least bit comfortable? The ION LT features reduced weight by removing the previous swivel and by adding our ultra-flexible braided MaxFlex hose.

Brushed Aluminum Styling

The ION LT's high-tech accent rings are machined from a solid piece of aircraft Aluminum, then hard-anodized utilizing a unique process to prevent corrosion. 

Computer Optimized Design

AERIS regulators are exclusively designed using the latest 3-D computer modeling techniques. This allows us the ability to model and test performance while still in the early stages of development. The ION LT's unique deflector vane and housing design diverts airflow from the valve directly to the mouthpiece, producing smooth venturi-assisted inhalation. 

Oversized Integrated Purge Button

Adding to the ION LT's rugged durability, an oversized integrated purge button is utilized to eliminate the possibility of free-flow caused by trapped sand. 

Patented Orthodontic Mouthpiece

To further reduce jaw fatigue, the ION LT features an all new patented orthodontic mouthpiece with high density bite tabs designed to accommodate the natural overbite of the human jaw. 

Nitrox Compatibility

The ION LT is classified as being suitable for use with nitrox breathing gas mixtures containing up to 40% oxygen by volume without the need for special preparation, cleaning or component parts. 

WORK OF BREATHING
Did you know that it costs energy to breathe? The amount of energy your regulator requires to move each liter of air is called work of breathing (WOB). Lower work of breathing equals lower effort required to breathe and increased comfort and safety during a dive.

How to Read Work of Breathing Charts
The computer-generated breathing machine chart presented above represents a regulator's performance per standards established by the U.S. Navy's Experimental Diving Unit. Tests are conducted at 198 feet with approximately 3000-psi supply pressure, 25 breaths per minute of 2.5 liters each.

(1) Inhalation - The chart shows one complete breath cycle, starting with inhalation on the left and continuing along the bottom to the right, staying mostly below 0.0; thus the inhalation work of breathing is reported in negative numbers.

(2) Exhalation - The exhalation effort begins on the right and runs across the top to the left. These are all positive numbers since a diver (or the machine in this case) is blowing out (exhaling) rather than inhaling.

(3) WOB - The total area inside the loop formed by the two lines is what the computer analyzes to calculate the regulator's total work of breathing - the amount of energy the regulator requires to move each liter of air.
