Here is what a filter like that will do.. I pulled it out yesterday for a short 45min job- to show. 50 feet 2.5 inch and 50 feet 2 inch vac line with a greenhorn. The diesel burner was set to 210 degrees. So travel time to carpet and back was not too long. Blower is roots 45.
It was a short time so only one side caved but you can imagine how it gets...the other side is also permanently damaged.
