Trade in your older SPARE AIR for a brand new one!

Spare Air trade-in allowance

For a limited time, we're offering an $80 credit towards a new Spare Air when you trade in your old 1800 psi model or 3000 psi model. Our newest models feature an always-on design that supplies life saving air in an emergency without any requirement to turn a valve on and much more breathing time than the 1800 psi models.
