Specially designed for remote on/off functions, it is normally connected in parallel to an operating machine which, when switched on or off, simultaneously activates or deactivates the aspirator as well, making a decisive contribution to reducing electricity consumption and the noise level produced since the aspirator will only work when the operating machine is also switched on.

This function, if equipped with a timer, also allows the system to be switched on at pre-established times.

There are 3 operating modes: neutral / manual / automatic.
