How To Choose
If you're on a budget, will only be performing mask training, or are comfortable sleeping in the small Head Bivy altitude tent, the Sierra 100 is a great choice. If you prefer simplified altitude adjustment, are more sensitive to noise while sleeping, or want to use any of our larger altitude tents, choose the Everest Summit II. If you want a rugged, stationary unit that can be upgraded to supply an altitude chamber, the HYP 123 is the way to go.
How Altitude Generators Work
Our altitude generators draw in ambient air from the room, reduce the oxygen percentage to match the selected setting, then supply this hypoxic air to a tent or mask via a length of tubing. There are no tanks to replace or annoying maintenance to perform. Simply turn it on, set your simulated altitude, and start training!
FAQs
What’s the noise level of the generators?
It’s comparable to the sound and volume of a window unit air conditioner. Specifically, the Sierra 100 produces about 65 dB of sound and the Everest Summit II and HYP 123 units both produce about 60 dB of sound.
How much power do they use?
The generators draw between 550-650 Watts. So for a 110V unit, between 5-6 Amps of current, and for a 220V unit, between 2.5-3 Amps.
What's included with a generator purchase?
We offer packages for each generator, allowing you to bundle the accessories you need at a discounted price. Simply visit the page for the generator you're interested in to see the available options.
Do they include a warranty?
Yes! All of our generators include a 1 year/2,500 hour warranty with the option to purchase an extended warranty.
