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.

I have a question for you guys. The hose that goes from the pump to the top of the element has a fitting in the middle with a1/8 inch hose connector that goes out of the unit and ends up at a vent location. I pulled the hose out of the drain pipe turn on the pump and a considerable amount of water comes in that tube and goes into the drain. I have no idea what it’s for, but it appears that hoses capacity is greater that the supply capacity, emptying the water tank too soon. So, I removed the hose and plugged up the hole and the supply can keep up with the consumption. My question is, what heck is that for? It doesn’t look like something temporary or used to drain the supply at the end of the season. Thanks in advance.
