Where can I fill my HPA bottles?

Recommended Posts

Where can I fill my HPA bottles?

 

Typically vendors aimed at Scuba-Diving, Paintball, and Airguns have air compressing services.

 

 

High Pressure Air Bottles/tanks can be filled by several methods:

 

 

 

1. Air Compressor
These come in many types, both mains and fuel powered. Their operating pressure must meet the required needs of the bottle to be filled, many low pressure compressors exist for a multitude commercial purposes.

2. Hand (stirrup) Pump
Pumps commonly have at least two or three stroke so that air is compressed during both the compression and the return action. It has been noted that for certain pressures a minimum bodyweight and strength are required.

 

When operating a pump for extended duration care should be taken to monitor the temperature and moisture build up on the apparatus.

3. Scuba Tank

Using specific tools, a scuba tank can be used to fill several HPA bottles.

4. By connection to another bottle.

Linking a bottle which is larger or contains air at a higher compression should allow another bottle of lower volume or lower PSI to be filled by direct connection and temporary free flow when using appropriate equipment.

Limited General Information on HPA Bottles:
I don’t presume to be exceptionally knowledgeable on filling HPA, the purpose of this thread is to provide assistance finding a location to fill HPA bottles, and though it is not to educate on how to fill them I will update accordingly.

HPA bottles come in several sizes including, though not limited to those below. Usually in the majority constructed from aluminium or carbon fibre.

3000 PSI: 13 CI, 35 CI, 48 CI, 62 CI
4500 PSI: 48 CI, 68 CI, 100 CI
1 Cubic Inch (CI) is 16.387 Millilitre
Common Pressures Conversion:
Usually everything on the airsoft/paintball side of things is in PSI. However often other industries in the UK use BAR.

A basic PSI Conversion chart:

70 PSI = 4.82 BAR
100 PSI = 6.89 bar
120 PSI = 8.27 BAR
300 PSI = 20.68 BAR
450 PSI = 31.02 BAR
800 PSI = 55.15 BAR
3000 PSI = 206.84 BAR
4500 PSI = 310.26 BAR
Don't count on this chart for science. :-)
