SPARE AIR IS QUICK AND EASY TO REFILL!

Spare Air is a refillable fully self-contained breathing device. Store the Spare Air at full pressure and refill it only if you use it or need to travel on a commercial airline. The always-on regulator is ready to deliver life-saving air in an underwater emergency or toxic air environment. The optional Dial Gauge displays an accurate pressure reading in increments of 200 psi. The pressure indicator white pin will extend completely out when the unit is filled. The pin will recess into the pressure indicator when the unit requires refilling.

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

Refilling from SCUBA Tank

Spare Air can be filled using the SCUBA tank refill adapter attached to a filled 3000 psi SCUBA tank.

Thread the 910S Tank Refill Adapter onto the check valve port of your Spare Air.
Place the refill adapter onto a filled SCUBA Tank. Slowly open the tank valve to allow the pressure to equalize, filling your Spare Air.

Refilling at a Local Dive Shop

The Spare Air can be filled at most local SCUBA Diving Shops using the optional air compressor refill adapter.

Thread the 920C Air Compressor Refill Adapter onto the check valve port of your Spare Air.
Attach the compressor whip to the refill adapter. Release air into Spare Air to 3000 psi.

Refilling from a personal Breathing Air Compressor

If you have several Spare Airs to refill on a regular basis, a Nuvair Breathing Air Compressor may be your best option. Available in both Gas and Electric models.

Thread the 920C Air Compressor Refill Adapter onto the check valve port of your Spare Air.
Connect the adapter to the air compressor yoke and turn the compressor on, filling the unit to 3000 psi. (Electric Model shown)

Refilling from a Hand Pump

Thread the pump yoke onto the check valve port of your Spare Air.
Like inflating a bike tire, fully charge Spare Air to 3000 psi for maximum air capacity.*

Note: if the unit is completely emptied of air in any underwater conditions, refer to the manual regarding proper servicing before refilling your Spare Air.

*Refilling a Spare Air to capacity using a hand pump is extremely strenuous and time consuming.
