Quick question, need the name of a part.

[THE FAMILY GUY]

I'm building a d.i.y filtration system. I need the name of the part that was commonly used in some sumps. It looks like a helicopter rotor and it spins and sprays the water onto the media. Can someone name that part and tell me where I can purchase it.....thanks

I don't know the correct name for it but try rotating spray bar for sump or check out Spinning wet dry spray bar DIY from 2010. The issue is the holes tend to clog up in the spray bar if it isn't pre-filtered.
