Refilling Spare Air

Pressure Indicator: Spare Air requires filling.

Pressure Indicator: Spare Air is filled to 3000 psi.

Dial Gauge: Shows actual pressure in psi.

SPARE AIR IS QUICK AND EASY TO REFILL!

Spare Air is a refillable, fully self-contained breathing device. The always-on regulator is ready to deliver live-saving air in an underwater emergency or toxic air environment. The pin on the standard Pressure Indicator will rise while filling and when flush with the top, unit is full at 3000 psi. The pin will recess into the pressure indicator when the unit requires refilling. With the optional Dial Gauge Pressure Indicator the needle points to actual pressure in psi or bar. Spare Air should be stored full or with some positive pressure to prevent contaminants from entering the cylinder. Store in a clean, dry environment with optimum temperatures of 50-75ºF for best product performance. Avoid direct sunlight, automobile trunks or other areas subject to temperature extremes. Industry guidelines recommend replacing air in cylinders annually.
