Re: R 404 A
For R404A you need Ester oil. I've been using ICI Emkarate as it is what the local wholesaler stocks.
Available in three grades/viscosities 32,46,68 dependant on the type of compressor used and the temperatures you are running at.
Some compressor manufacturers recomend thier own brand of oil for certain compressors (special additives).
Phone up the compressor manufacturer or their distributor and see what they recomend.
