Sanisplit NK3 230 V AC Tecma (T-PF.SPLIT/NK230V)

The Sanisplit NK3 230 V AC by Tecma (code T-PF.SPLIT/NK230V) is an automatic lifting unit for grey water, designed for onboard plumbing and for managing discharges from fixtures such as sink, shower, and bidet. The system is designed to transfer discharges to the collection tank even when the slope of the system does not allow natural flow.

Operation is managed by a pressure switch which automatically starts the pump when the level in the collection tank is reached. The presence of the check valve helps prevent water backflow, improving the stability of the discharge circuit.
