I am considering replacing the RPC connection to my 5hp air compressor with a VFD. The compressor seldom runs, as most of my shop needs are satisfied with the little 220 1ph "tank on wheels". But, shop space is getting tight, so I'm thinking to have only the larger unit plumbed to all points, wired in a way that I need not remember to turn on the RPC before energizing the compressor. (Oh to have 3ph off the line ;-)
It seems that compressor duty would fall under the "hard starting' designation, though I have never had any trouble with the 5hp RPC in service now.
I have a NIB Siemans VFD that might suit the task
I am not actually considering using the drive to vary the motor speed, though at times I consider slowing the darn thing down to a more rhythmic pace.
Will anyone care to comment on the application of VFD to compressor service?
TIA

PS I did a "search" of this forum with the key word "compressor" and got back the entire form list. How to narrow the search?
