Air arms FTP 900 fill pressures

[Rickenbacker]

Hello and welcome to the BBS.

I don't own an FTP, but I assume the 90-110bar you mention is most likely the point at which you'd want to refill the gun.

The recommended filling pressure of the FTP-900 is 200 bar (2900 psi) this will return the
best performance. It is acceptable to increase this to 220 bar (3190 psi) for general practise, the
overall shot to shot spread on the charge will rise slightly but you will benefit from extra shots.

That is fill pressure ^^^^.

Although every gun is slightly different the recommended refill pressure for the FTP900
is between 100Bar (1450psi) and 110Bar (1595psi).

So as I assumed above - that ^^^^ is the point where you'd normally stop and refill the gun.

And I believe you should get upto around 100 shots out of a fill. 1 bar per shot isn't a bad 'rule of thumb'.
