So I now have the HF 5hp 60gal.
Current setup:
It is wired through a 50a plug with 8/3 to a 40a 2 pole 240v breaker.*@#$ Vibration isolators are due to arrive today, it needs it. It is not yet bolted to the slab since, while it is in the right spot, I am undecided about its rotation. *@#$It is plumbed with a street 90 to a close ****** to a full port ball valve to a 6 inch ****** to a regulator/filter to a quick connect, all brass all 1/2". *@#$The switch is factory set at about 165 and 120 psi. *@#$It takes 58 seconds to recover.
Some thoughts about it:
The good

rice.
At 800, best value I have found.
Not nearly as loud as I thought it would be.
Well built.
It has a bit of a rumble and slab vibration which *@#$I expect the to go away when I put it on isolators.
Compared to what I have been using, this thing is a beast.
The bad:
The terminals in the switch housing look like the are for maybe 12 ga wire with the ground screw even smaller.*@#$ It was a struggle to get the 8ga in the terminals.*@#$ I had to drill a separate hole for the ground and anchor with a small bolt, washers and a nut.
The indifferent:
Would have been nice if the air outlet was 3/4".*@#$ It is 1/2".
The tank pressure gauge is next to the pressure switch which is under the edge of the *@#$motor/pump bracket.*@#$ Hard to see right now since the tank is currently oriented so I am parallel to the belt.*@#$ I think I may rotate the tank 90 so the belt is perpendicular to me so that the switch and the gauge are facing me.
The future:
Going to add a ****** to the oil drain to extend it from the pump.*@#$ Right now it is a bit messy to change the oil since the plug is relatively flush to the pump and doesnt allow the funnel to sit properly,
Havent added a tank drain yet but will.
Will extend the plumbing from the regulator to a flex hose to hard pipe (undecided on material) to two drops plus a retracting reel.
A week in....would buy it again
