Could you post a link of where you tried to reach out to them? 

I tried contact OEM through their authorized distributor from which new airend was purchased but couldn't. They kept on asking questions through distributor and after two months denied warranty without sharing basis.

What tests have you done on the compressor? 

There are no tests. We replaced its airend with new one. During test run, found high vibration measured with CSI Analyzer. As per vibrational analysis, Gas Pulsation Frequency is appearing.

One source I find on line states that the machine is rated to 46°C (115°F).  If this machine is outdoors in sunlight I could see where the ambient temperature might be a factor.  

Hi Fahad, IR engineering teams nearest hub to you are in UAE and Italy. I have some contacts. It will be good if you share more details about bearing failure under the thread, IR air compressors are common, we have 10 units of similar model. 

Hi! Y7. We have four such units at our site which normally gives 1 year useful life. There are number of contributing factors for failure. Dominant mode of failure is High Vibration.

Can you kindly answer my following questions:

1- Are your units direct drive rigid transmission? If yes then does these have soft starters of DOL operation?

2- What is air quality level? How frequent you are replacing air filters? Are you using filters from OEM?

3- What's the duration for separator element replacement? We are getting alarms at a period of 2 months so need to get replaced due to choking?

Please revert with answers to following questions then we can discuss few specific failures as well.

Thanks.

Regards,
