Indoor Range Lead Recovery Vaccums

Anyone know the manufacture or a source for the equipment systems contractors use to separate boolits from the rubber ship material backstops?

I have spent plenty of time on the end of those machines. Not fun work by any means. Ours were built in-house. Think leaf blower with a heavy duty impeller. It only moves the rubber, the rounds stay on the floor.
