2.2 kW WASINEX VFA-10T 380V — water pump frequency inverter with float switch function

WASINEX VFA-10T 2.2 kW 380V is a three-phase frequency inverter designed for water pump control and constant water pressure applications. The unit adjusts pump speed according to actual pipeline pressure, helping to reduce electricity consumption, minimize water hammer and extend the service life of the pump and pipeline system.

This model is designed for 380V three-phase systems, with three-phase input and three-phase output. It is suitable for residential water supply, booster systems, garden and agricultural irrigation, swimming pool water supply, commercial water supply, industrial water circulation and cooling water systems. WASINEX states that this type of constant pressure VFD system can help save water and electricity compared with traditional water supply systems.
