How to Fly with Spare Air

When carrying SPARE AIR on a commercial aircraft, the system must be empty and according to TSA regulations, the regulator must be unscrewed from the cylinder so they can be sure that it is empty. 

1. To empty all the air out of the SPARE AIR press the Purge Button until no more air is released. Unscrew the regulator from the cylinder counter-clockwise (no special tools are needed – it is screwed on hand tight).
2. If the regulator does not unscrew easily DO NOT force it or use tools, instead soak the entire SPARE AIR in a 1-1 vinegar & water solution overnight to loosen any salt corrosion. Leave o-ring, washer and exhaust discs on the regulator.
3. Place the regulator and cylinder in a Ziploc plastic bag to protect and keep them clean. (Option - purchase the "SPARE AIR Travel Pack" which includes its own carrying bag - see below.) Keep SPARE AIR regulator and cylinder threads clean and dry. Include SPARE AIR Owners Manual so TSA employees can refer to it if they have questions.
4. Pack SPARE AIR in your checked or carry-on baggage.
5. Reattach the regulator and cylinder and refill SPARE AIR when you reach your dive destination. You may lightly lubricate the tank o-ring with a small amount of silicone spray or grease - NEVER use a hydrocarbon based oil. DO NOT force regulator onto tank - if you feel resistance stop and unscrew and start again.
6. Replace tank o-ring after product has been disassembled and reassembled 3 times, or o-ring shows signs of wear or air leakage. Tank O-ring size is 016 and you should be able to purchase from any dive shop.
