info about aqua tech 3ph powerhead

[prodrumernate]

ive been searching online the past hour trying to find out if my aqua tech 3ph is submersible or not.i know power heads normally are.but want to make sure before creating my sponge filter.i read someone had put it in the water and it broke.yet i read it is submersible.nowhere on it does it say it is.while my 4 other power heads do.but this has the adapters and things i need to create my sponge filter for my hex tank.
