I want air on my van for motor bike weekend sport but don’t want to carry a compressor and generator.

Is it possible to mount a receiver to underside of my van and fill it from small compressor at home.

If so will a larger tank mean longer lasting air supply. Also will it keep pressure for a long time.

Robin, “Is it possible to mount a receiver to underside of my van and fill it from small compressor at home” absolutely yes, if there is room to mount an air tank below the chassis. Maybe it would fit best on a rack behind the bumper?

“If so will a larger tank mean longer lasting air supply” Again, yes. The larger the filled air tank the longer that air is available to use. In particular, if you are stingy with air use, and dial the pressure from the tank to the lowest setting where it will work with a regulator, air will last even longer.

“Also will it keep pressure for a long time.” Yes, as long as there are not leaks in fittings and so on there is no reason why the air tank should leak at all.

When you pump up the tank with pressure, you are introducing water vapor with the compressed air. You will need, then, a way to drain the tank periodically to ensure that the water that condenses from that air isn’t sitting at the bottom of the tank and starting a rust issue.

You might also, depending on what you want the compressed air for and the size of the tank, consider using a small compressor that can be powered from the accessories plug in the van. It will take a long time to fill a tank of any appreciable size, but then, it can also fill the tank when driving along.

Just be sure that, if you have a small compressor capable of delivering a certain air pressure that the tank is rated for 25 PSI more than pressure.
