Graf Overflow Siphon DN 100 w/ Rodent Guard

Differs from the standard overflow siphon with the inclusion of a slotted steel rodent guard. Dirt particles that are lighter than water (e.g. pollen & dust) settle on the water surface as a floating layer. This floating layer is removed when the tank overflows by means of the overflow siphon in the tank. Also aids in mosquito prevention.

This model includes a slotted steel plate which prevents rodents from entering the tank in applications where the Internal Minimax® filter is not used.

When used in conjunction with a Calming Inlet, the Overflow Siphon prevents mosquitoes by acting as a water trap where mosquitoes cannot enter or exit the tank.

Connects to standard 4" PVC using a Fernco fitting.
