Frequently Asked Questions

What is the difference between the Spare Air 910S and 910C refill adapters?

The 910S uses a ring pressure release valve to vent pressure once the connected tanks equalize, while the newer 910C uses a bleed screw for the same purpose. Both are yoke-style adapters that refill a Spare Air from a standard SCUBA tank up to 3000 psi. The manufacturer produced the 910S through July 2025 before introducing the 910C.

Will this adapter work with a DIN tank valve?

No. The 910S is a yoke-style adapter and is built to connect to a standard SCUBA tank that has a yoke valve, not a DIN valve.

How full does my SCUBA tank need to be to refill my Spare Air completely?

The source SCUBA tank needs to be fully pressurized to 3000 psi to achieve a complete fill of your Spare Air unit.

Which Spare Air models can I refill with this adapter?

This adapter is built to refill Spare Air Industrial Safety units, the Spare Air Xtreme Sport (1.7 cu ft), and the Spare Air Xtreme 6 (6 cu ft), connecting each unit's check valve refill port to a standard SCUBA tank yoke valve.
