Old sears swamp cooler/with pictures

Anyone recognize this swamp cooler (pictures attached) - I can not find any markings to what model or any identifying marks except there is a date of June 06 1986 on the inside. She says it is a SEARS.
Need to replace the filters (pretty old)
The filters rotate on a motor driven roller
I am trying to fix it for a 96 year old lady.

 

Here's another thread that might be helpful to you.

And here is one more. You might get lucky and find these are from the same manufacturer as the one you are working on.

Old Rotobelt Swamp Cooler

 

That looks like one of the Essick built for Sears units. They've discontinued those belts a while ago. You may have to measure and come up with a physical size needed. Then you could check locally or post the size here.

 

Man, I'll tell you … when they discontinue .. they discontinue, and that's that …..
The filter measurements: 23 inches wide x 26 inches long. But it is "LOOPED" so double the length and add probably 2 inches to go "OVER" the rollers.
I also have been looking for some "SAME" type material. Maybe I can duplicate them and use that.
I did find out that the model is a Kenmore: 661.623920 and the filter number is: 42-6293 (which is no longer available ((of course))) And the company that made them is no longer in business. Essick Air told me this. However, I continued searching, to no avail!
So my best bet would be to find some material (other than that straw type stuff sold at the hardware stores-which deteriorates pretty fast).
So … anyone with any ideas is more than welcome to post … and thanks for the help!
