Dry enough air for pumping a PCP ?

[Solvo]

The Dry-Pak system for stirrup pumps is very effective and will provide dry enough air IF you maintain it.
For it to work well the media needs to be changed frequently (maximum life is 3 months, less with heavy use).

If you don't change it often it does nothing, and you will get water visibly condense within all the connectors and by extension of course the air lines and cylinder.

are all the dry packs like this or similar ? http://www.airgunbuyer.com/ecommerce...0Dry%20Pac.jpg

we used activated alumina n our air dryer in the compressor place i worked at . we used to go to -40 dew point but it can go way lower as much as -100 i think

i have a bag of it here . just a safety specs sized bag (the bag is from a pair of safety specs) i got some for a friend to use in his air dryer in the workshop but he did not use it so gave me it back .

once it stops catching the water you put in in the over to dry off then reuse it .




from what i read the hills pump dry pack stuff cant be dried out and re used .

not sure if it would work in the airgun pumps.

Think the clue to the problem there is the word 'borrowed' as you have no idea if the bolt had been tinkered with etc (and here I would suggest maybe it had), never a fan of m/s rifles for HFT or HT, and as haven't used a post 2014 Scorpion derrivative, would be reluctant to comprehensively endorse one, although I am sure that should I get to play with one, I would not be left wanting.

No - a guy tried to sell it and on trial the bolt "turned out to be loose" (sorry for the pun). This defect was mostly seen on FAC Scorpion guns, I learned later.
