Basic handpump for PCP rifles, likewise HPA handpump tanks and small scuba tanks.
Works fine, no problems - you'll just need to assemble it yourself out of the box.

Let us know if you might need a more premium / better option and we'll assist.

This pump does feature an inline filter for catching microbial matter that might otherwise pump into the rifle. Does not feature a dessicant housing however, you could always make a plan by stuffing a bunch of dessicant sachets into the handle sides (by removing the handle rubbers. Stuff some in on both sides. You can stuff in as many as you'd like, just minding that some of the sachets don't tear and release silica balls through the retainer screw. That being said, as a safeguard, push some low density foam in first, then the dessicant sachets. Re-fit the handle grips afterward.

Remember to chuck some silicone drops down the 2nd stage shaft on occasion, to lubricate the pump. Likewise, thread the handle off and chuck some droplets into the third stage shaft.

There are some people who say that, chucking some coolant in the 2nd stage tube, does help keep the temperature in the pump down, likewise, increases the lifespan of the seals, which does make sense. We'll leave this up to you guys to decide and experiment. We ourselves found that, just using the handpump indoors, away from ingress and regularly lubbricating w/ silicone oil, minimizes O-ring friction and keeps the pump running happy, w/ no failures on the seals.

1.How long will it take to fill a 450cc tank?

The first time you fill it will take a longer as you are going from 0-3,000 psi. So the first time like 20-30 min. It will take at least 15 pumps for every 10 bar pressure of your need in the 450cc tank. It all depends on how tough you are really.

2.Can I use this with paintball air tanks or the Pioneer Air bow ?

If you have the right fill adapter for the connector.You can fill them that has a 8mm female Foster quick-disconnect on the end of the pump hose.

There is a 50cm(20INCH) hose with the pump.
