There are several ways to have your AirHog Supreme/AirHog Piglet Supreme filled.
The easiest of course is to take it to your local friendly Scuba shop and have them fill it for you. However, some Scuba shops can only fill to 3000 psi because of the output capacity of their air compressor. Even so, some Scuba Shops will have the ability to "ram" to 4500 psi. If you are unable to find a Scuba shop that can perform the "ram," you might try going to your local Fire Department.
Fire Departments, even rural ones, have a compressor that has an output capability of 5000 psi that they use to fill carbon-fiber Fire-Fighter tanks. Be sure to check with them first, and if they are able to fill your AirHog Supreme with compressed air to 4500 psi, then order your
Fire Department to DIN Adapter shown below... don't forget to take along a box of donuts!
Another possibility is to also check with a Paint-Ball store nearby to see if they can fill your AirHog Supreme to 4500 psi with Nitrogen gas. If they are able to, order your Paint-Ball to DIN Adapter listed below. Nitrogen gas is a dry gas- it is virtually moisture free and the best gas you can put into your PCP!
Last but not least is filling your AirHog Supreme/AirHog Piglet Supreme with totally dry nitrogen gas and never worry about condensation or corrosion inside of your PCP air rifle or air pistol. First of all, check with nitrogen gas suppliers such as AirGas, PraxAir or a nitrogen gas supplier nearby to make sure that they have 6000 psi nitrogen gas output. Then order your very own Dirt E. Harry Nitrogen Regulator right now and start prolonging the life of your valuable PCP air rifle or air pistol!
