Hydrovane hv02 compressor?

[lalojamesliz]

My brother in law gave me one of these compressors when I was searching for and found my 80 gal.
He is a bank manager and he told me it was very expensive and they used it for like 2 yrs at his branch. I don't remember why he was able to take it but I know i don't have to hide it from the police

I don't see much information about it online on what uses it made for and my brother in law doesn't know exactly how it was being used. He would just walk by it all the time while it was being used and he said it worked when he took it home.

I did see that it has a built in after cooler/ heat exchanger and oil carry over is less than 3ppm and its quiet. I'm wondering if I can use this to paint a car or something that requires clean air.

Well, has a heard of these?

I think it puts out 8cfm @145psi

I've rebuilt many Hydrovanes since they were something of a speciality of our shop. It will be fine for painting if you use good quality filters and maintain them, although I would run the compressor through a tank since using it straight through a hose or piping network will cause excessive inlet valve cycling which will accelerate wear. I've seen many hooked up directly to pipes with no receiver and it's really not an efficient way to go. Any oil flooded screw or vane needs the air/oil separator inside them replace on schedule or there will always be problems with oil carryover. Same with overheating. Proper rotation on startup is critical. This should not be an issue if this is a single phase motor.

Congratulations on your acquisition. It absolutely kicks the *** of that Eastwood QST in terms of quality.

No. You should not keep this for anything special. You should mount it on a nice horizontal tank and use it as a general purpose air compressor like it is designed to be.

See what the Eastwood QST30/60 is selling for. Now realize you have something much better than that for FREE.

You will not get anything like this for less than a couple of grand. And it looks like the electrical is ready to go. Think about that when you read guys posting about which POS throw away consumer grade Harbour Freight fakeroo 5hp piston compressor they are trying to decide to buy.

I'd give my left nut for this as a home compressor. What's the USD to Pound Sterling conversion these days?

Thanks man, I mean Mr.Mac

I just saw the 8cfm rating and compared it to my 80gal. Thank you for showing me how valuable this is. My brother in law told me to keep it or sell it but either way its mine.

Yes on the electrical. It has a plug to connect on the end of the cord. I think its set up for 120v. I'll have to open the wiring box on the side of the motor to see what its wired for. It's either 120 or 240v.

What size receiver would you recommend having this on? I know it had to be good because it has a 1725rpm baldor motor on it but i had no idea its this good of quality

 

[lalojamesliz]

5, 3 and 1 are wired together
2, 4 and 8 are wired together
It doesn't look correct to ME by looking the wiring diagram but I'm not familiar with working on electrical. It was used this way for two years so I'd imagine that it's correct.

I think a 30-40 gallon tank would do, but a nice 60 gallon horizontal wouldn't be a waste if you have the space.

It's wired for 110V and the rotation was reversed by interchanging leads 8 and 5.

As it sits, it's a constant run machine with a simple on/off switch. You may need to pay for some electrical expertise if you want it to operate start/stop. Constant running won't hurt it since it's a 100% duty cycle, and it's actually better for it to keep it up to temperature. These machines will last practically indefinitely with proper maintenance if they aren't destroyed by running them out of oil.

I'm worried about the oil..... its at the very bottom of the sight glass. As soon as I tilted the unit it showed up. At first I thought they ran it dry I wouldn't expect a bank to keep these maintained like I would.
I noticed it while wiping the unit down.Pennies to them I'm sure.
So it has oil but its just very low. I'm not going to test it until I replace the oil and add new synthetic that I used on the two stage pump on my 80 gal since it works great with it.
That and it has a 20a male plug. I have a few 20a outlets with normal style outlets in my garage that I had added but I'll switch out one of the outlets to this type and I'll try this out.

I wonder why its reversed. Any idea?
Thank you so much for helping me out with this

Be careful what oil you use. Vanes normally require a somewhat heavier oil like a 40W since their operation dictates that the blades are held out by centrifugal force against the inside of the stator and sweep along at a fairly high rate of speed. They need good film strength to prevent excessive wear of the blades faces. I'd use whatever Hydrovane recommends and stick with that. I believe we used Shell Tellus 150 as a cheap alternative to the rather expensive CompAir stuff. Other company's equivalent oils will work just as well. Rotation was probably reversed just to match the required rotation of the compressor pump. They are directional.

Normally you just fill a Hydrovane to overflow.

Great information thanks.
I hate to keep asking but any special instructions on how to drain and fill this guy? I think it has a drain plug on the bottom and i was going to dismantle it looking for a fill plug.
Gotcha on the oil. I'll find the proper oil. Thanks

I picked up this HV02 for my home shop. Looks to be in decent shape but unfortunately I don’t know the history of how it was used or serviced. Planning to change the oil before firing it up (still trying to figure out what oil is suitable to use). Does anyone have a service manual the HV02? Would love to do a teardown and rebuild if I can get my hands on the manual.

I wonder if the bank used those transfer tubes where you put the money into a cannister and it gets carried away to another area. Looks like a great find!
