High Pressure Pumps

[WILBA]

The cost of the cylinder has not been included
It's comparing the cost of refilling a cylinder you already own, to buying a pump which then saves the refill costs.

Some people DO need to fill a cylinder because they only shoot away from home & need to refill the rifle during the day (& in that case the cylinder still needs to be tested)

What I do not know is whether these pumps provide DRY air, certainly they don't have filter packs built in, although they sell them at about £160,
so I suspect they might just use a centrifugal/cyclone moisture trap which will reduce moisture content, but is far from DRY.

Can't you buy an inline drypack type filter to use with these compressors?

Yes, I even say so in the post you quote , didn't you read it they're about £160.

Thanks for the replies chaps, not unduly worried by the economics but the dry air question is of more concern.
if you have someone quite close and convenient with a dive bottle compressor that's fine but the place where I've had mine filled in the past is only open quite limited hours and I think he's hoping to retire completely sometime soon.
