Vent Axia eDemand Frequency Inverter 3Ph 18Amp 444176

The Vent-Axia eDemand Frequency Inverter (Three Phase, 18 Amp) provides advanced demand-based ventilation control for A/C speed-controllable motor fans. Built to handle intensive HVAC applications, this inverter features an IP54-rated enclosure for environmental protection and durability.

It includes quick-start functionality with pre-set modes for easy commissioning, and total motor protection through thermistor connectivity. An LCD multifunction display allows for intuitive monitoring and configuration. Two analogue inputs — 0 – 10V (external power supply required) and 0 – 20mA — enable integration with CO2, temperature, and constant pressure sensors. Manual speed control is available through a 0 – 20mA remote input.

As part of the Vent-Axia eDemand range, this 18A inverter supports both single and three-phase systems and incorporates a built-in sine filter to ensure smooth, efficient motor operation. All models share a unified user interface and can be used with IP54-rated twin fan auto changeover panels, complete with adjustable duty share timers for balanced and reliable airflow management.
