Product Information
The Spare Air 920C Air Compressor Refill Adapter is a refill fitting that lets Spare Air and HEED 3 emergency breathing units be filled directly from a full-size high-pressure breathing air compressor instead of a SCUBA tank. It threads onto the check-valve refill port of the Spare Air unit and accepts a yoke-fitting compressor whip, allowing air to be released into the unit up to 3000 psi.
Who it is for
This adapter is built for dive boats, dive stores and travel destinations where a full-size SCUBA compressor is on hand but a tank-to-tank fill is not practical. The manufacturer calls it "a must for dive boats, dive stores or travel destinations," since it lets operators refill Spare Air and HEED 3 units using the same compressor already used to fill SCUBA tanks.
Key details
- Fill pressure: up to 3000 psi
- Part Number: 920C
- Connects to any dive boat or dive store full-size compressor equipped with a yoke-fitting whip rated to fill SCUBA tanks to at least 3000 psi
- Threads onto the check-valve refill port of the Spare Air unit; the compressor whip then attaches to the adapter to release air into the unit
Compatibility and sizing
The 920C is compatible with Spare Air mini SCUBA breathing devices, Spare Air Industrial Safety units, HEED 3, and the Spare Air Xtreme Sport and Xtreme 6, since the Xtreme models thread onto the same refill port as the 910S adapter. It is intended for use with standard dive shop or dive boat full-size SCUBA compressor systems that have a yoke-fitting whip rated to at least 3000 psi.

The 920C is compatible with Spare Air mini SCUBA breathing devices, Spare Air Industrial Safety units, HEED 3, and the Spare Air Xtreme Sport and Xtreme 6. The Xtreme models use the same refill port as the 910S adapter, matching the 920C's connection.
What kind of compressor do I need to use the 920C?

How does the 920C adapter attach to a Spare Air unit?
