Roots 45 on Judson Nitro

[CarpetKING]

Any of you guys have a roots 45 on a nitro or know if it will fit/clear pulleys and motor?

 

[Bob Savage]

Call Judson.

I'm sure they can tell you.

 

[CarpetKING]

Yea I talked to les said it wouldnt fit

 

[Greenie]

didya ask Les what was the largest pulley ratio you could use on your existing 33 to turn it faster, those can spin fast, just noisier.

 

[hogjowl]

Yeah, over drive it and this is one of the times I recommend an Odin vac booster.

 

[CarpetKING]

Didnt think of that Greenie. Hopefully I can squeeze a little more suction out of the little blower. The new greenhorn definitely helps my drying times just looking for ways to get even quicker dries.

 

[Jay D]

if you run it at 3600+rpms you WILL notice the difference But don't go over 15hg. Mine runs at 3600 and it runs like a grape ape.

 

[Greenie]

If Doodaddy was on here he'd tell ya it will spin 4000 if you want it to.

As far as "lift" I doubt you'd ever see more than 13" with a glided greenhorn, it'll only come up if you suck up the cat or drapes by mistake.

Just run some synthectic in it

 

[CarpetKING]

Thanks for all the info. Gonna go by Les's Monday and see what I can do

 

[Duane Oxley]

You can boost it up to 15% overdriven with no noticeable longevity problems. That's 115% of the motor speed. So, if the motor is turning at 3,600 without a load and drops to 3,450 under load (which is typical), then Greenie was close in his statement. The actual result would be 3,967.5 RPM.

And it does provide a noticeable difference.

 

[hogjowl]

Did you screw me when you told me to run 30 weight motor oil in my blower?

Thanks for FINALLY getting me a bill.

 

[Duane Oxley]

No. When that blower was made, Roots was putting in their owner's manuals to use 30 or 40, depending upon ambient temp.

All we've ever used is 30.

 

[hogjowl]

It may be all in my imagination, but my blower was making a funny sound yesterday and I thought of you.

 

[SuperFly]

You want your blower to last longer use
Dresser Roots Blower and Compressor
High Temp Synthetic Lubricating oil

ISO-VG-320.. or even 220..

30w is really risking your blowers life..

 

[Ron Werner]

depends on how often you changed the 30W, In my big red I was using 30W, never knew any different, its what the guy I bought it from told me to use. Changed it every 100hrs

 

[Guest]

Should go more than that,but it is you Ron Anyway,synthetic can go 2500hrs under normal wear and it runs slightly cooler.

 

[Leslie Judson Jones]

Judson has about 1500 Roots 45 blowers in our industrial vacuum systems. These systems run continuous 24 hours a day, 7 days a week. A lot of these systems still have the original blowers in them. These systems have more than 200,000 hours on them. All these vacuums use 30 wt. non-detergent motor oil in the blowers. The manufacturers of the blowers that are being sold today recommend synthetic oil. I received a memo suggesting that you can now use Mobil 1 synthetic oil in blowers.

 

[Ron Werner]

and changed how often Les?
I wasn't changing it every 100hrs because I was being anal, I was told that was the frequency.
I'd rather change it every 500!

 

[TimP]

with non-detergent oil. I think you can go at least 300 hours. I switched to synthetic on my blower for my last change. And I run synthetic for my cat pump and change it every 500 hours now.

 

[Duane Oxley]

500 for non detergent petroleum- based oil is the recommended interval

First oil change is to be at 100 hours, then every 500 thereafter

I tell people to do it based upon an assumed use of 100 hours a month / 25 a week, since 25 is about the max that a full- time cleaner puts on the system in a given week (Most do less, few do much more...)

So, change the oil every 5 months is my recommendation. It's easier to plan for, IMO.
