This is a small room that acts as a shortcut between the Gel Refinery Site and the Gel Hall. Samus must shoot a red switch to activate a Grapple Swing Point. Then while swinging, Samus must shoot another red switch to activate another Grapple Swing Point. Then after a third red switch is hit, Samus will be able to make it all the way across this room.
The room contains a large machine which features spinning rotors, which sift through the lake of Fuel Gel below them. This machine is part of the Gel purification process, hence the name of the room. The Grapple Points in this room are a method of traversing the room without falling into this mechanism.
