All our large blowers are Hoffman and the small ones are of the roots type. I don’t know the cut off point on the capacity. The Hoffman blowers have been blowing since the plant was built in 1952. I think I saw one being repaired in my tenure. We covey both plastic particles and powdered chemicals by the tons.

GD has good cross section of both types. They did have a very good technical support group.
