Office duster/HC152A conversion

Possibly, I don't have one. Buy one and send it to me.

I have one, Sent me a can and I will test it for you.

Just looked at Techspray Duster- it is 1,1,1,2 Tetrafluoroeth ane aka 134A!

So, I'm reading the links and have a couple questions.


the guy at the s10 link has ester oil in his list of stuff to get. Is this the same as the pag150?
Does the pag150 with uv already in it have any drawbacks?

Is a wrecking yard compressor a better idea than a remanned unit? I have heard nothing but bad about re-manufactured compressors and how half or more go bad in a short time.


Thanks.

I would buy a new compressor instead of a rebuilt.

From what little reading I have done, pag will work as long as there is no mineral oil in the system.  I don't think they used mineral oil since some time in the '90s.  Not sure what new compressors come with but I think ester and pag are compatible but I would double check that with some googling

Most systems use PAG because it doesn't wear out like Ester can. Most compressors are dry even though they use a very small amount of oil to assemble them.

I used PAG150, IIRC

I got the side can tap and the vac pump and gauge setup. Haven't opened them up yet as we have volleyball this am. I have to pick up some more duster cans as the kids took and used the ones I had. I think I can use this duster with the mineral oil. And I can mix the pag150 with the mineral oil in the system. Am I wrong? Steve sez I am above.
What can I do short of pulling it all apart?

I am on a budget and would like to get it up and running but will hold off and get the drier and orifice if we think it is necessary. I want to do it right but with my economically challenged state I am doing it on the cheap. The system is stock. Really. I bought it new and nothing but running the A/c until it didn't blow cold any more. I just left it be as I didn't have the knowledge or tools to do anything.

Thanks for the input. I can start another thread but thought this one being added to was better to keep it together.

I'm told you want to change the orifice if for no other reason than that's where
trash from dead compressors etc will accumulate

I'm not sure it has a dead compressor and was going to pull a vacuum on it and try to fill it with the duster stuff. While in the meantime saving up for the orifice tube and drier. Jason hooked me up with a compressor so if the initial deal doesn't work for long I can swap the compressor and hhe other new stuff on and clean it real good then. Poor plan?
