Fill rate slowing down

[paddydiver]

MY Coltri Mch6 has about 60 hours on it and the fill rate seems to be slowing down quite a bit over the last few fills. I use it lightly. Normally only filling 1 tank (or 1 twin set) per fill, 10l 12l or double 10's per use. Filter and oil are changed regularly, a little more often then recommended by the manual.

Before I go looking at it myself is their any pointers from more experienced people on here? Maybe the belt needs tightening? Anything else I should be looking at? It's not a dramatic slow down, but definitely slower then it was.

Third cylinder ring blow by. Basically it's a super cheap compressor and not expected to last.

.....It's expected to last more the 60 hrs!

I’ve got over 140 hours and 400 fills and still getting the same fill times. And pump to 300bar.

It's down by a matter of minutes over the last few fills. Cylinders usually have at least 50 or 60 bar in them, fills fine up to about 150 bar then slows down more then it used to get up to 220.

I did experience this, but it turned out to be the gauge needle sticking as when it got to 260 bar it would jump up; I changed the gauge that fixed it.

Check with soap solution for leaks on fill hose fittings...nothing then try other fittings...not certin how air temp and humidity would change compression rate, if at all...
