high vibration problem in elliot air comp

[ramsharan]

sir,
we are having only elliot 350 pap 3a compressor.it runscontinuously.in recent past we facing high vib problem on LS bearing.after repair it hardly runs for a week .recenyly we found that fresh oil viscocityat 40 degree celsius is 25 centi srokes where as recommeded is 32.question is can we blend the oil with higher viscocity to match therequirement.
pl.comment or suggest the source.
thanks

If you need to use an oil with 32 Cst at 40ºC that means an ISO VG 32, you need to select an R&O (Rust and oxidation inhibitor oil) iso vg 32. If you want to reduce the vibration levels I recommend you to use high film strengh lubricants such as Royal Purple oils.
The viscosity ISO 32 have a range between 28.80 and 35.20 cST so you are not in this range, and need to replace the oil.
