Nice 447.
You got 3 phase to run that?

got it for 700$, came with a Sullair air dryer Ill get this week. Factor in the value of the dryer and it's a decent price.
I don't have three phase or I'd put a 15hp on it, and get 51.8 Cfm at 175psi. This is a 10hp, so I can easily switch it to a 10hp single phase. 36.5CFM at 175psi is already enough. ***** to have to remove that motor, the thing is like brand new. Someone will be happy to get that one for used price.
I paint cars and do powdercoat. I want to use the new sandblast non-stop to save time, and be able to put 2 da on it. The duty cycle on this HDI is 75% .
For the rest of the stuff I do...even the dresser is overkill, but you can't have too much air.
It's gonna be quieter as well, 590rpm versu my already tame dresser at 700. That's why I get industrial units, they run slower and thus cooler and quieter.

10hp Single phase is kinda the bottom lower limit for that monster.
People don't relalise how big that pump is.
Sitting in my shop getting drunk and snapped this 10 mins ago. 247 Devil Bliss. 19.5CFM or 25 if I upgrade to 7.5HP.
1/2 the size.

You can run the 447 on 7.5hp, thats the limit as it needs 500rpm minimun.
It says so on the pumppapers, but it's never been commerciallized as such.
I wanted something to max out 240V. Can't find 15hp single phase, too rare and only in closed frame motors, so even more expensive.
Nice 247 right there Ross, My friend would love it. Only reason he can't take my Dresser (18.5 cfm at 175psi) is because my dresser is horinzontal. Btw, ill be swapping to those filter you have on yours.
People dont realise how big they are until they have one in front of them. Even your 247 is massive . My pump alone weight 425lbs and 24 inches high by 30 inches lenght and 24 inches width.
Cant wait to get it off the truck and inside to play with it

People often question the need for the 247. Same foot print as any other 80g and can be found used for the same / cheaper than most China made Comps.

Bought this 500l dual chinook k30 pump compressor to replace my old 350l single 2 stage pump. Only paid a couple 100 euro.
Now in the proces of customizing it to get a dry air output. And i will have to rebuild a pump

So I had a duplex 445 setup present itself and was curious if those were just the predecessors to the 447. They seem to have similar performance specs but best I could tell was a mist lube system. Still researching a bit. I thought it was an outrageous price, but through the crappy pics I saw there was a 2nd pump sitting on the tank.

Got myself a Devair VAT-5063 with the infamous DV447 4 cylinders pump
I just got it functional yesterday but wow that big boy is filling up the tank really fast !
If you want to see the installation/wiring of my compressor, you can go here to see lot of photos I took of during the process :

Picked this up for $150 today. 5HP, 230 Volts single phase, AMP compressor. Got to fire it up...couldn't plug it in but it was in really good shape. I figured I can't go too wrong here but I am optimistic it will work fine.

A couple of days ago I posted about my 80 Gallon AMP compressor that I bought for $150. I am happy to say that I discovered that my compressor is a rebadged Saylor Beall model VT-PL-730-80 and made in 1995. Here are pics of mine and the Saylor Beall. I am ecstatic because this means I can get parts and this is a great quality compressor. This will be an especially HAPPY Easter for me.

This may not be the best place to ask, but does anyone know good places to list an antique compressor for sale? I've got a 57 deVilbiss here that's only taking up space, but I'm not willing to scrap it and would like to see it go to a collector or otherwise good home. This is what it looks like assembled, right now the pump, motor, and tank are separated.
Edited to add: I found it a good home, living in a wood shop.

Sorry this is SO far past when you originally quoted - and maybe this is answered further into the thread (I'm new to the forum and have only gotten this far into the thread so far) - but since there's no receiver on a rotary screw, wouldn't the output air be even harder to dry, because there's nowhere for the moisture vapor to 'condense out' of the air stream??
And, if the above assumption is correct, wouldn't that mean installing a higher-capacity air dryer and thus increasing cost/complexity?
Believe me, I'm not married to recip compressors - I actually like the idea of rotary screw units - I'm just confused about getting the moisture out of the air...

After about 5 years, I finally have my compressor operational.
In the fall of 2010, I purchased an Eaton 60 gallon vertical tank compressor. I had it delivered to my folks farm as my Dad bought an identical one at the same time. At the time, we were planning a move to Michigan and that would have inculded building a new house. Well, life takes strange turns. The next summer, we downsized big time and moved to Florida. I didn't take my compressor as I just didn't have the room. Instead, I wrapped it with stretch wrap and it sat in a machinery shed for 5 years. In 2014, we moved again to the Atlanta area and built a proper house. This past fall, I drug a trailer up to my folks to pick up my compressor and a few odds and ends that we had room for again.
While building the house, I roughed in 1/2" copper drops in my garages. This house has two, a main 3 car garage and a 30'X25' lower garage. In the lower garage, there is a 8'x8' "closet. That is where the compressor lives. I had a 60 amp sub panel installed in the closet when we were wiring the house. The copper was stubbed into this closet as well.
Yesterday, I'd decided that I had waited long enough and went to HD to get more copper. I needed to run about 70' in the attic above the main garage and tie into my drops.
All the drops come off the top of the trunk line and the entire trunk line slopes back towards the compressor. I used a length of hydraulic hose to tie the compressor to the copper.
The compressor sits on a little platform that has hybrid caster wheels under it. Each wheel has a rubber foot that threads down to the floor, taking the load. If I need to move the compressor, I can thread the foot up and the caster wheel takes the load.
Today, I finished up the tie in and pressurized the line for the first time. No leaks. There is some Legacy epoxy enroute and I figured I'd need air during the prep.....

Most of the screw-type compressors that I have seen, at various places of employment, were set up with twin-tower desiccant air dryers on their outputs, with automatic controls. One tower is in the air stream at all times, while the other is getting regenerated (heated to remove the moisture).

So, just out of curiosity, do rotary screw compressors create more/less/same amount of condensate as recip piston units, per volume of air?
redmondjp
Well-known member
Educated guess: the same amount.
Screw-type compressors are best for large air users where there is a continuous demand for air. They don't do well in start-stop situations so aren't ideal for most smaller users.

OK - here's my contribution:
"New to me" 80's era Champion VR5-8 5HP 80 gallon compressor, w/a R15-A pump and a relatively new 5HP single phase (converted from original 3 phase by prior owner) I just unloaded at my place in exchange for three short days' labor helping an old friend move... rated at 17.3CFM delivery @ 175psi. Also got the magnetic starter you see attached to the receiver and a wall-mounted 60A disconnect as well - just need to get that much power out to my garage, wire it all back together, plumb some lines and I'm off to the races.
Along with the compressor I scored a cast iron Vermont Castings Dauntless woodstove + all the stainless steel Metalbestos chimney I need to vent it out a side wall on my first floor and all the way up past my second floor to clear the roof rake! You can see the back of the stove in the background of the photo - haven't had time/money to do anything with either, since I'm renovating my house out-of-pocket as well.
I know the compressor runs - seemed to take 15-20 minutes to fully charge the tank to 175psi, then through a series of 6 cycles it averaged just under 2 minutes to recharge from 140 psi... not sure if this is normal/fast/slow, but the recharge rate is reliable so not too worried.
Can anyone tell me if those charge/recharge cycle times are way off?!? Also, what particular stuff should I be looking for with the tank being a 1980 vintage? I'm not sure how any other previous owners cared for the beast, but the PO (my friend) didn't use it terribly often and I'm pretty sure the tank was drained regularly as the guy is pretty careful - almost OCD - about his tools.
I hope to have the woodstove in by next winter and the compressor has to wait until I either get a big enough generator to run it or get the time/money to better wire the detached garage where it's stored... my wife heard it running and quickly put an end to my plan of putting it in my basement!

My compressor is almost ready to be used. One head has an unloader that leaks and I need to get a motor to run it, but the other one works well. Very nice sound, deep and powerful, not tinny and annoying. Overall the best $250 I ever spent. I have about another $600 into getting it running, $300 for the 10 HP (single phase) motor and starter, $150 for the Barry isolators, and another $150 in misc fittings and parts.

Formula for CFM: (TANK GALLONS x 0.536 x PSI change) divided by SECONDS
80gal x 0.536 x 35psi / 120sec = 12.5cfm
cosmopedro

Wow - I did not know that formula... Extremely helpful - if undesired - information...
On the plus side, 12.5cfm isn't all that shabby - and considering the cost and ready availability of repair parts, not an insurmountable issue.
Thanks, sld961!

Very nice. I think I have the same Quincy. Care to explain the entire system? Looks like a large auxiliary tank, a dryer, and maybe a timer on your drain valve?

You're welcome. The "real numbers" were a little lower than I was hoping for when I finished my compressor build as well. I built a Franken-compressor with an Emglo L pump (ca. 1983), 3hp GE motor (ca. 1974) and a 30gal, 200psi tank.
The cfm listed in the pump literature was quite high. I didn't expect to get 21cfm with a 3hp, but I was hoping it was in the high teens. It ended up at 13cfm from 0 to 120psi, then 12cfm from 120 to 140psi, which is about where you would expect a 3hp to be. Overall I'm pleased with the results. Still need to clean the tank up and paint it.

You pretty much nailed it. The extra tank is a former "hot water maker", ASME coded tank I picked up free (500 gallon). I had my youngest son inside the tank after installing to clean it out! My former compressors' tank rusted out (1941) so I installed a automatic tank drain my boss gave me on a replacement tank and subsequently transferred it to the new system. It blows down every 15 minutes. New compressor is a 5 HP, 17.2 CFM @ 175PSI. I purchased 2 Quincy filters and spare cartridges for each. The refrigerated dryer is valved in a by-pass so I don't have to run it continuously.
