How many times up to 4.5 psi

Post by zambuluca » Thu Nov 07, 2013 6:42 am

Hi, in the manual of AE 1041 it is shown that to reach 2.0 psi takes about n. 07 strokes, for the main chamber. So this is the question, How many strokes to reach the right pressure (4,5 psi) ? and and especially what is the volume of the pump used to say this?
for the first question the answer shold be +/- another 9 times
but for the second i don't know.
Somebody can help me ! Thanks Luca

i would seriously recommend that you buy an inline pressure guage and not just trust how many strokes of a pump! considering that air pressure changes with temperature and altitude, it wil always remain a guessing game and make it difficult to do a quick check on an increasingly hot day when all that air starts expanding .

All rights, but the main chambers of AE1041 (and 1040 the same) have got the Boston valves and i have tried to get information with the sevylor-gauge for boston valves, which doesn't work with the valves of the Airfusion . :evil:
So if I have right understood the gauge on the pump doesn't work whith the Boston V., and so i'm trying to find another way, or somebody know a pressure gauge that works with the Boston :lol:, but in europe i have found nothig. :oops: Thanks Luca

Answer to your first post.
The pumps were determined using the Advanced Elements Double Action Hand pump w/gauge.
2x2000 cm3

Here is a gauge that can be used to check exact pressure for a Boston Valve.
