I pretty much concur with Kevin Jenness' recommendation for a low rotation speed pump reciprocating air compressor for the OP at this time.. Get a 7.5 hp if you want some extra capacity. I agree with the Quincy, although I would rate a Gardner Denver over an Ingersoll Rand industrial compressor. With proper care, it will last for years. I would stay away from home center machines. You will pay more but will have a quieter machine that will withstand a wider range of temperature, and require less attention. This type of compressor could be purchased used due to their long term durability.
To maximize your compressor, I recommend
1: Locate in well ventilated area where heat generated by compressor is easily dissipated.
2: A larger tank to add more capacity buffer and reduce cycling.
3: Horizontal tank instead of vertical, to lower the center of gravity and lessens the impact of inherent vibration
4: Place on vibration pads to minimize vibration effects
5: Plumb inlet air from outside if in cooler weather zone and no shop air conditioning. This will cut down noise around the compressor.
6: Create ¾” loop to connect all usage to minimize pressure drop and add storage buffer and reduce cycling
7: Pressure regulator at output to avoid pressure swing effect at usage points.
8: Accessible tank drain to remove water daily
If your usage demand grows and develops a constant usage over time, you could move to a rotary screw that is sized for constant demand, and use this compressor as a back up and auxiliary supply for higher peak demand. You could plumb it in series to add buffer storage and automatic supplemental capacity.
By the way, I sold industrial air compressors for 3 years before entering the woodworking industry.
Regarding the rotary vane configuration, it would be less critical in tolerance compared to a rotary screw. I agree, you will have to replace the vanes, as the design requires centrifugal force to thrust the vane edges against the compression chamber, resulting in vane edge wear. It will be more forgiving in terms of contaminants in the air.
Rotary screws require bearings to maintain precise relative position of the screw lobes. Thus the stringent oil change requirements. Inlet air contaminants could cause lobe damage in extreme cases.
