What size blower is this on your 327?
and will we be able to test one @ Vegas?

Bill Bruders said:Guys its all good. I appreciate the opportunity to answer peoples questions and concerns. No matter how hard you try to build the very best products little things just happen. I'm sure every manufacturer is commited to their customers but I'd put the people in my company up against any of them for their passion to make things right. We can't address issues we don't know about so keep it coming we will take it all in and do the best we can.

And if anyone wants to know they drove up from AZ that same day to check it out. They have addressed the issue with the builders on the assymbly line and am confident they won't have another leave the plant that way.
Oh and Bill it is ok to kick Hoody in the (_*_) when you see him i'm going to when i get home. :mrgreen:
P.S. Hoody be sure and Clean Charlie's Litter box before we get home :wink:

There are several differences between Bilobe and trilobe blowers although they vary by manufacturer. So I will focus on the Gardner Denver (Sutorbilt) brand
1. From a vacuum performance persepective trilobes go approximatlely 2 inches deeper into vacuum than their bilobe counterparts at the same HP and torque levels. So they are more efficient.
2. A trilobe blower creates less vibration which reduces stress on the truckmount frame and other components
3. The reduction in vibration reduces noise
4. The shaft size of the main drives are larger and handle torsional shock between the motor and blower far better.
5. The oil lubrication systems on a trilobe are cleaner than the bilobe grease type and provode better heat distribution as well as overall lubrication
6. Finally trilobe blowers use ring seals on the lubrication system rather than o-rings
Of course these differences come with a higher cost but all in all we believe they are worth it. When Mike Roden was at Prochem he worked on the engineering team along with engineers from blower manufactures that developed the trilobe design for the cleaning industry just as an FYI.
Bill Bruders said:Ok Bob lets talk CFM's and Volume of air definately important stuff
One of our Industries dirty little secrets is the use of component manufacturers engineering specs as perfomance specs for performance data. The restoration segment has been real bad at this. 4 years ago I called on industry leaders to mandate independant testing of airmovers as an example an provide real CFM data. Unfortunately they choose not to take a stand. I'm saying this because many a manufacturer of a snail shell airmover will claim 2000 to 3000 CFM, the truth is not even close. The best you can get is about 1550 and that is using a 1HP motor most units produce less than 1000 CFM. Velocity is about 35 MPH Axial airmovers are better at CFM but many times lack Velocity which what really dry's. For people who think the airpath is just a "barn fan" I'm sorry but I can prove the superior performance of the product anyday.
Ok so how does all this play into Bilobe and Trilobe blowers? Well system design is the biggest component of real CFM's and velocity so each TM manufacturers design is big part of this discussion but I don't want to start a he says she says war on this issue so lets talke generically.
Just looking at the enineering CFM's of a blower without calculating the pressure curve to determine how the additional load of water vacuum hose etc. is going to impact it is risky. Rather than get into a this brand that brand discussion lets say you have a bilobe with a free air no load 450 CFM rating and a trilobe with the same free air specs. The added power of the Trilobe in terms of the additional 2 inches of vacuum, the improved performance from the lack of vibration which takes horsepower to over come, the improved lubrication which reduces the units temperature which keeps internal tolerances tighter will result in better extraxtion performance.
Sorry if this is more techy than you wanted but the answer really is a multi facited one
bob vawter said:Sorry Bill but i WAS hoping for a little MORE techy.....lets talk about the volume of the extra lobe witin the volume of the case....and find out HOW the volume of air expelled can be greater at the same RPM....what am i missing here?
Greenie said:Jezus Bawb.....It's a ssimple as three little bites of air, or two Big bites, it's nominal. Airflow has never been the issue, most blower are capable of far more airflow than you will ever get through a 2" wand....let alone the industry standard 1.5" wand.
Noise attenuation and vibration are the big deal, not cfm.
That and being able to run at a "higher" vacuum point, 16"hg beats 14"hg.
Can we get on to other things like telling Mike what BRAND of clutch comes stock on the Butler, and where he can get a suitable replacement on a Sat. morning?
