Oxysaver Cannula, this comfortable device may be used in place of a mask at altitudes up to 18,000 feet MSL. It has a conserving feature that can extend your oxygen supply up to eight times.

Aerox Flowmeter/Indicator--this device not only indicates oxygen flow but also reads directly in thousands of feet MSL.

Aerox Flowmeter/Indicator has dual scale--useable for Oxysaver Cannulas or masks.

Aerox Adjustable Flow Valve--an all metal, thumb screw operated needle valve allows you to precisely control flow. The adjustable needle valve is attached to the outlet end of the connector supplied with your system. Flow can now be controlled precisely for altitude and type of equipment (Oxysaver cannula, mask or regular cannula). The flowmeter and needle valve may also be co-located.

I have an older Cessna, the built in O2 system works fine, but no mask fittings...this took care of that issue, and Ive used PLENTY of O2 masks, but the cannula design, at first seems like it would be odd/uncomfortable, instead I found it works great and actually is more comfortable then the standard type mask, plus I can still use the Bose A2 headset!

I really like this system. Iâm my Cessna 210 with onboard O2 it saves a huge amount of gas. However, it gets 3 vs 5 stars though as the edge under the nose is sharp and itâs uncomfortable after a short amount of time. I recently wore it for 4.5hrs straight and ended up with a small cut (like a paper cut) between my nostrils. They really should have figured out how to not have a sharp edge touching your nose., especially for this price.

Product is good, but I wasnt sure by the description if I was getting the fittings (which I wanted) or the fitting and hose/nasal part. Also, I wasnt sure if by a set, they meant 2 or 4. Turns out, it is 1 fitting and hose/nasal part.

Q: Do the retrofit kits come with just the connector or do they include the cannula and flowmeter?

The retrofit kit will come with everything needed including the cannula and flowmeter.

Q: I have a Cessna T210L. Not sure if itâs considered new or old style. How can I tell?

You would need to look at the photo break down of the adaptors to see which style(old or new) matches the connector on your aircraft.
