Why air compressor do not give required pressure?

Question

It is a broomwade compressor. Only get 2 bar. supposed to get 5 bar.

Answer 1

Besides major leaks or premature bleeding, you may want to check:

(1) intake filter, if this filter is too dirty the inlet pressure will drop to make the outlet pressure also drop

(2) control panel, anyone tampered with the max pressure setting?

(3) if it is a water-cooled, check water level, too hot a cylinder head will cause a lower compression ratio

(4) if you newly installed it, double check that you did not mistakenly wire up a wye instead of a delta to get the right HP and RPM for the 3 phase motor given your local 3 phase voltage. And that you did not wire it up to rotate in the wrong direction which may cause the lubricant to run dry and thus raising the head temperature

Answer 2

I'll believe your air compressor valves or piston is leaking, thus cannot built up the requirement amount of air you need. Check any leaks outside, maybe hoses or valves. Then, call a mechanic to rectify it !

Answer 3

You will find a brass safety valve on the air tank.Adjust this by turning nut on valve CLOCKWISE to INCREASE PRESSURE or ANTICLOCKWISE to DECREASE PRESSURE. Only make very small adjust ments each time & keep an eye on the pressure gauge.

Answer 4

If its has inter or after coolers check the coolant flow.
