So have bough a new bigger compressor for the garage, the one I used before was my dads and was acting up and also way to small for any kind of air tools more.
So ended up with a dual piston compressor powered by a 5,5 bhp motor, really wanted a bigger tank for it but the garage is limited in size, might try to get an extra tank for it later on if I feel its needed.
Box ready to be opened:
And what it looks like:
Dug right into it since Im installing an hour meter to keep track of run time on it, yes I know the minus for the meter should not be to ground but cause of an issue with the big connector to the compressor it will be like this for now:
A bracket for the hour meter and bolted it to the hole that had the ring for lifting the motor, was a bit tight but got it in place:
All bolted up and functioning:
Full flow outlet and 2 regulated outlets:
And a little video about it:
Timed it and it fills the 100 liter tank up to 10 bars in 2 minutes.
Unit was purchased from a company Drift och Underhållsteknik.
Time will tell if if was a good purchase and it holds up well.
10bar x 100L = 1000L air pumped in 2 min so the compressor did an average of 500L/min. Obviously the rate was faster in the beginning and slower towards the end.
I would be interesting to follow the pressure meter with a stopwatch and note down the times for 1 bar … 2 bar … 3 bar etc. That way you can easily calculate the compressor capacity at different air pressure.
Its listed to have a rate of close to 500 L/min at 6 bar pressure.
So your math might be spot on!
Had a problem with the pressure switch but they just sent me a new one and it works great again.
