Avra Cohen: cabinetmaker and avid scuba diver. I am a volunteer diver at the NY Aquarium. I am well familiar w/ cyclonic dust collection, now looking to build an underwater model that will separate out sand. We have powerful vacuum w/ 2" hose built into the exhibits, but need to separate out sand to redeposit it elsewhere in the exhibit, while keeping it from getting into the system where it will chew up the impeller.
Welcome any thoughts on modifications that would be useful or thoughts on consideration of the difference between airflow vs hydrodynamics. I think a Thien baffle will be needed for the same reason it is appropriate for sawdust collection.
