Since some paintball cylinders go up to 4500 PSI, you are limited to filling 3000 psi bottles at the local dive shop. If you ever want to go to the higher pressure tanks for more shots per fill, you will need your own high pressure compressor. An electric 4500 psi compressor with paintball filler will run you $2750 and will put out scuba grade air. After the initial filter runs out, paintball grade filters are available at a reduced amount. However, with the small compressor, it will take about one or two minutes to fill your bottle and you should get about 500 fills before you need to change the filter so the cost there is minimal. Also, if you hurry, there is a special for free shipping on compressors shipped before DEMA. Drop me a line at
