Seal Vent Opening in Ingersoll Rand Sierra SH300
Seal Vent Opening in Ingersoll Rand Sierra SH300
(OP)
We have oil free package Ingersoll Rand Sierra SH300 and observed that 1st stage airend and 2nd stage airend seal ports are blowing heavily hot air. Is this a normal phenomenon? please see the attached photo.
I understand, this ports(openings) will leak only whenever there is a seal failure. however vendor advised, they shall have air blow even during normal running.

Thanks for your reply.
Yes. I can do this. however still I need to understand; during normal conditions (seals are ok), should we see any air coming from these openings?
Please note that, this unit still under commissioning! it is recently installed.

for a new machine there really shouldn't be any significant flow but should be more of a "seep"
Get the seal data. I've been surprised before at how much is still within allowable range.
