Good morning, colleagues, I want to ask a simple question of whether or not we can get into the subject so much. Can I change oil to mineral to a 2hp Tecumseh compressor that comes to work on r404 and put it to work with R22? The issue comes where I am the R 404 is too expensive and the customer has 2 bottles of unused R22. The equipment will be installed in a freezing cellar

HELLO FRIEND, BASICALLY ALL THE COMPRESSORS ARE EQUAL, THE PROBLEM IS THAT TECHNICAL PART THAT YOU DO NOT WANT AND THAT IS NOT REACHED TO ALL INCLUDED ME. AND IT WOULD BE SOMETHING SO, REACTION COULD GENERATE WHEN COMPRESSING GAS, THAT TEMPERATURE COULD RAISE THE HEAD, WILL RESIST THE FLAPER, WILL HAVE A, PERFORMANCE AGREEMENT. THAT ONLY IN THE PRACTICE CAN YOU VERIFY IT OR HAVING EXPERIENCE, I PARTICULARLY AND TESTED A MACHINE OF 12 LOAD YOU 134 AND I WAS PERFECT. AND YES, YOU CHANGED AN OIL FOR 22, THE VALVE OR CAPILLAR ALSO CHORD, FILTER. AS YOU SEE IT IS NOT JUST CHANGING GAS. REGARDS .

you would have to change expansion valve for r22 since 404a is a mixture .......
