Sutorbilt has released their new MR series blowers (increasing their lead over Roots).

The gearbox is designed to run 15 degrees cooler at the same power input.

Viton Seals have also been improved to allow higher vac lifts.

One mounting bracket design allows both horizontal or vertical configurations.

So, everybody pushing the Vac Lift ceiling like we are, can benefit from the new design.

Re: New Sutorbilt Blower Design

The question here Larry is, Will the Cobb's units come with them standard or an optional upgrade? :D

Nate;

They will be standard equipment on all of our TM's.

The real question is how much additional lift can they generate.

Re: New Sutorbilt Blower Design

As a TM Mfg. I would be asking how much will it add to the cost of the machine.

ps: Lift is generated/controlled by the relief valve, so how good is the relief valve?
pps: are the waste tanks being beefed up to handle the additional load?

If it runs 15 degrees cooler, does that mean heat exchanger machines will also run 15 degrees cooler solution cleaning temperatures?

Loren;

The 15° cooler gear area is due to better isolation between the impeller volume and the gearbox.

The gearbox and lubricant is the critical temperature for long life.

The exhaust might even be slightly hotter. :)

Where did you get the cool degree sign from? I've looked over my keyboard and don't see one.

It is one of the extended ASCII characters.

Search for it and you will find several other characters you can use like:

Looked at a blower in the new Sutorbilt 5LR series (#59) today.

The gearbox is separated from the impeller airspace.

The engineer had some thermal Infrared photos that showed the substantial reduction in heat at the gearbox.

Not to hijack, but regarding blower sizes....

What is the difference (vac performance) between a #5 blower (like what is used in the BL Thermal Wave II) and the 59 blower?

Re: New Sutorbilt Blower Design

Same 5" gear, just one has 6" wide lobes the other 9" wide lobes so it delivers much more CFM at the same rpm. Because of that, the 6" wide lobe is rated at a higher Lift level than the 9", it's all about stress on the shaft and gear, a 9" lobe put smore stress on the Components than a 6", so pick your poison, high flow or high lift? Also the 9" requires more HP to drive it.

These photos show two Infrared thermal images:

Top image is MP Blower showing heat transfer into "Gear Area"
Bottom image is MR Blower showing no heat transfer into "Gear Area"

Caption from MR thermal image:
With FEA thermal analysis, a good design was made great.
• Innovative bearing housing design with air gaps
reduce gear end sump temperatures by 15°F,
extending lubricant, bearing, and blower life
