The e-Fly is a specialized Mac3 float switch that can effectively handle dirty water. Its surface fit and finish have been meticulously crafted, resulting in a smooth and sleek shape that can slice through suspended solids in a tank.

e-Fly Float Switch– dirty water can’t touch this!
The e-fly always remains in the correct position because of the integrated counterweight. An external counterweight (and the ragging point that it creates) is not necessary.
Like its big brother, the Mac5, the e-fly dirty water float switch is available with PVC, H07RN-F and H07BN4-F in 5, 10 and 20m lengths. The e-Fly is also available (as a special order) with ATEX certification (in the same cable types and lengths).
How to configure the e-fly Float Switch
There are two main ways the e-Fly is used:
- Slaved to a single pump for emptying a tank. You can either wire the float switch into the pump with a suitable t-joint or outside of the tank itself using a simple junction box.

Or, as part of a level control setup. As this diagram shows, the e-Fly is suspended from the top of the tank (or attached to an internal pipeline /fixture. The pipework must be sturdy enough to support the extra weight). The level is adjusted on each float by shortening the cable or lifting the attachment point onto an internal fixture.
This array can then be connected to a controller creating a versatile level control system for sewage or turbulent water.
Overall the e-Fly can be deployed in a very similar way to the Mac5 – but where it truly excels in areas where the sheer size and mass of the Mac5 are not required. For a domestic sewage treatment plant the e-Fly is perfectly at home.
