Hydrovane Compressor Noise

Recently brought a used Hydrovane PU23. Is it normal for these to make a boiling/bubbling noise like a kettle once they are switched off? Haven't quite got around to understanding how these compressors work, to know if this noise is normal?
 
Don’t know a huge amount about compressors but I would firstly wh3n you stop the compressor open a tap and dump all the air, if the boiling bubbling noise stops investigate air side. But more likely water in engine cooling is the culprit so very slowly and cautiously check radiator cap, do not burn yourself if engine is likely to be at operating temperature

On my Hydrovane that's an engine powered one, the instructions are to not release pressure when shutting down


I can hear something on the pump side while the pressure gradually reduces.

Is your oil level correct in the pump ?

A man has pleaded guilty at Newtownards Magistrates’ Court to waste offences relating to a bonfire next to the electrical sub-station on the Circular Road in Newtownards, Co. Down.

Gareth Gill (51) of Abbot’s Walk, Newtownards pleaded guilty to two charges under the Waste and Contaminated Land (Northern Ireland) Order 1997, for which he was fined £150 each and ordered to pay a £15 offender’s levy

On June 25, 2018, PSNI officers went to Gill’s yard, where they found a large amount of waste consisting of scrap wood, pallets, carpet and underlay.
