Compressed Air Filling

SCUBA Fill Tips:

These insructions for CO2 are adapted from the supplier of my CO2 filling - contact y2kta at hotmail dot com to purchase if you want them too!

WARNING !!!!! Any leak with high pressure air is dangerous. Keep body away from such leaks as they can cut flesh. Never, never try to stop a HPA leak in progress, let the pressure drop to a safe level and then address the problem.

Check your o-rings, one in the SCUBA tank valve and one inside the QD on the fill station. Both should be lubed occasionally with a non petroleum based lubricant. Air gun oil or a silicon based product will work.

Your SCUBA fill station has a bleed valve incorporated into it (the knurled knob on the frame of the fill station). Make sure this valve is closed before you begin filling your HPA tank.

Your connection to the HPA tank should be secure (HPA tank will not pull out of the female QD on the fill station).

Open the valve on your SCUBA tank slowly to listen for any leaks, then begin the fill. Allow the pressure to equalize in the 2 tanks (gauges on the fill station and HPA tank should match), then close the valve on the SCUBA tank. Gauge on the fill station indicated remaining SCUBA tank pressure.

HPA tank can get hot during filling. Once they cool their pressure will drop a bit. If you are filling for immediate use , chilled wet towels will allow the HPA tank to hold more air. If you are not going to use the tank immediately you may want to top it off once it cools.

Open the bleed valve to vent any gas left in the fill station. Now it is safe to disconnect the HPA tank. (Failure to use the bleed valve may cause the loss of the small black o-ring located inside the female QD adapter on the station. The station will not seal unless this o-ring is in place.
