Refilling the Spare Air Xtreme Sport

The Spare Air Xtreme Sport is a refillable fully self contained breathing device. The included pressure indicator displays when the unit is pressurized to 3000 psi.


The optional Dial Gauge indicator allows for reading the pressure inside the cylinder in 1000 psi increments.


Extended pin - unit is full and ready to use.

Recessed Pin - Unit needs to be refilled.

The always-on regulator is ready to deliver life-saving air in an underwater emergency. Store the Xtreme Sport at full pressure and refill only if you use it. Service the unit if completely emptied of air while underwater.

Refilling is about as difficult as refilling a bike tire. There are 4 typical methods for refilling a Spare Air Xtreme Sport:

Refill at a Local Dive Shop

The Xtreme Sport can be filled at most local SCUBA diving Shops who are Spare Air Dealers using the optional air compressor refill adapter.

Attach the 920C Air Compressor Refill Adapter to the Spare Air Xtreme Sport

Attach the compressor whip to the refill adapter. Release air into the Xtreme Sport to 3000 psi.


Refill from a personal Breathing Air Compressor

If you have several Xtreme Sports to refill on a regular basis, a Nuvair Breathing Air Compressor may be the best option. Available in both GAS and Electric Models.

Attach the Spare Air Xtreme Sport to the 920C Air Compressor Refill Adapter.

Connect the adapter to the air compressor yoke and turn the compressor, filling the unit to 3000 psi. (Electric model shown.)

Refilling from SCUBA Tank

The Xtreme Sport can be filled using an optional SCUBA tank refill adapter attached to a filled 3000 psi SCUBA tank.

Attach the 910S Tank Refill Adapter to the Spare Air Xtreme Sport.

Place the refill adapter onto a filled SCUBA Tank. Slowly open the tank valve to allow the pressure to equalize., filling the Spare Air Xtreme Sport.


Refilling from a Hand Pump

In "extreme" circumstances where a SCUBA tank or powered air compressor may not be practical, a high pressure hand pump may be used to fill the Xtreme Sport.

Attach the Spare Air Xtreme Sport to the pump yoke.

Like inflating a bike tire, fully charge the Spare Air Xtreme Sport to 3000 psi for maximum air capacity.*

NOTE: If the unit is completely emptied of air in any underwater conditions, refer the the manual regarding proper servicing before refilling your Spare Air Xtreme Sport.

* Pressurizing the Spare Air Xtreme Sport to 3000 PSI using a hand pump is a strenuous, time consuming process.
