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.

Note: If returned, all cannulas and oxygen masks must be factory sealed.

Great product! Our old ones ( from 1987) failed on our way to Florida. Had our new ones shipped to Florida, which arrived early, worked great and fit perfect in our 2005 Ovation. Just recommend these to a fellow pilot on Mooney Pilots.

***** I purchased the AEROX kit to replace an A-3 Oxymeter that had developed a leak. The AEROX flow control valve is all metal whereas the A3 was plastic. It looks good though I have yet to use it. I will probably buy a second kit to replace another old A3 Oxymeter.

I needed to replace 3 cannulas and the attachments, these are a perfect fit for the PA-32 Saratoga II TC with a Scott/Aerox system.

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. I’m 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 it’s 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.

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 it’s 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.

Q: If I buy the retrofit kit, once I join the connector to the built-in overhead panel of my 1979 C-182TR, is there anything else that needs to be included to complete the breathing system?

You should not need any additional components.

Q: Whats the right SKU for Mooney Ovation 3?

13-18992 should be correct. Most Mooneys use the Scott type fittings.

Q: Is this compatible with Aerox P/N 4110-704-1 retro fit kit, I see two female connectors to the O2 source in the picture but the Oxysaver conserving cannula that comes with the retrofit has only one?

Yes, the 4110-701 is the correct replacement cannula in the 4110-704-1 kit.

Q: Have a Mooney M20L-R, what Will be the retrofit kit for the built in oxígen system?

That aircraft uses Scott fittings so our part numbers 13-18992 or 13-19711 would work.

Q: Can you buy just the fitting, without the tubing, cannula etc?

Yes, these can be ordered separately, however it is special order. Please contact our sales department for pricing and lead time for individual components.

Q: I have a factory oxygen system in a 1981 A36TC bonanza I need the kit to start using, there are ports that look like just a hole in the ceiling and the dash which kit do I need to buy?

The kit they call out for Beech Aircraft would be our part number 13-18992.
