    Scroll Air Compressor

    Anybody have thoughts on one of these. An impressive 12.7 CFM claimed, small size and quiet. Too good to be true?

    I think they've been in the medical community for some time but I haven't seen automotive ones before.

    Re: Scroll Air Compressor

    Seems like a good idea, but then so did the Wankel engine.

    Not sure I believe that a 30 gallon tank at 145 psi can be the equivalent of my 80 gallon tank running 175 psi. Seems like the laws of physics kind of get in the way there.

    Rated efficiency (in terms of cfm per kVA) is actually slightly lower than my old 2 stage piston compressor (made by IR I believe, sold by Sears).

    But lower operating noise would certainly be worth something. I mounted mine outdoors (and the "new" one will be outdoors as well), just so I don't have to listen to it run. Neighbors haven't complained (yet)

    Don't forget, you still need special wiring for it. It doesn't appear to come with a plug, and the instructions appear to expect it will be hardwired with a cutoff switch instead of a plug and outlet. So much for "completely portable" (unless you just happen to have a 20amp 220v outlet in all the places you might want to use it). "Must be installed by a licensed electrician."

    Nothing wrong with scroll compressors, but be sure to read the negative reviews before considering.

    Re: Scroll Air Compressor

    We have 2 large 15hp scroll compressors at work. They work great and are very quiet compared to a piston type (we have a piston for backup)
    Probably overkill for a home or small shop unit. Buy a good piston unit and add a chiller with the money you save.

    Re: Scroll Air Compressor

    Still looking for comments on using a scroll compressor in a small one person shop. I did read the comments, John, both negative and positive and am not scared away, at least not by the comments. I do appreciate Georges comments on his work compressors although the comparison to the Eastwood's smaller version might be a stretch.

    Also here's a bit about my situation. I already have two compressors, one 20 year old Campbell Hausfield 60 gal single stage and one 50+ year old Ingersoll Rand two stage 80 gallon, the latter already hard wired to a shut-off box. While the IR is much quieter than the CH, they are both very noisy. I do not have the option of setting up a compressor outside here in the frozen North like Randall does in sunny California. I have thought about building a shed for the IR compressor but that would cost as much as the Eastwood compressor. Also don't know how they would do in months of sub freezing temperatures in the unheated shed.

    I do appreciate the comments though. I'm only at the "consideration" stage with this and would rather have the negative comments now.

    Re: Scroll Air Compressor

    I have never seen a scroll this small. Large commercial units are more efficient , and quiet. I sold a 25hp unit a few years ago. I would put out enough air to do anything! Most of the large ones are 3 phase. I see this unit is single phase which is what most residential has. Much quieter, less power required to run them.

    Re: Scroll Air Compressor

    Yes, thanks Jerry, I can't seem to find anything to compare this with, although the big ones seem to be quite common. I wonder if there is any reason they can't be scaled down?

    Re: Scroll Air Compressor

    Here you go a bunch of smaller scroll compressors
    they cost a bit more than the Eastwood but probably better.

    I'm sure my dentist has one similar but not suited to garage application; they are tankless (no reserve) and only 4 to 6 cfm.
    From your username can I assume you have a 70 Triumph Herald?

    Re: Scroll Air Compressor

    Had a 70 herald. Rebuilt all the mechanical stuff. Brought the engine up to higher spec (similar to Spitfires so about 75 hp vs the normal 60) and drove it like I just stole it. But I no longer have as parking space for it and decided I wasn't enjoying the body work and it needed allot of body work so it had to go.
