Vent Axia eDemand Frequency Inverter 3Ph 8Amp 444174

The Vent-Axia eDemand Frequency Inverter (Three Phase, 8 Amp) provides intelligent demand-based ventilation control for A/C speed-controllable motor fans. Built into an IP54-rated enclosure, this inverter is ideal for commercial HVAC applications requiring robust protection and reliable performance.

It features a quick-start setup via pre-programmed modes and ensures full motor safety with a thermistor connection. An LCD multifunction display offers easy access to system settings and diagnostics. The inverter supports two analogue sensor inputs — 0 – 10V (requiring a separate power supply) and 0 – 20mA — allowing integration with CO2, temperature, and pressure sensors. Additionally, a 0 – 20mA manual remote speed adjuster provides direct fan control as needed.

As part of the Vent-Axia eDemand product line, this model works with both single and three-phase systems and includes an integrated sine filter for smooth, noise-reduced motor performance. With a consistent user interface across the range, the eDemand series also includes IP54-rated twin fan auto changeover panels equipped with adjustable duty share timers, supporting continuous and balanced airflow in critical ventilation setups.
