Vent Axia eDemand Frequency Inverter 3Ph2.5Amp 444172

The Vent-Axia eDemand Frequency Inverter (Three Phase, 2.5 Amp) is built for precise demand ventilation control of A/C speed-controllable fans. Enclosed in an IP54-rated casing, this unit is designed for reliability and long-term use in varied HVAC environments.

Ideal for advanced ventilation setups, it features pre-programmed quick-start modes, full motor protection through a thermistor input, and an intuitive LCD multifunction display. Two analogue sensor inputs (0 – 10V with external power supply, or 0 – 20mA) allow for integration with CO2, temperature, and constant pressure sensors. Additionally, a manual remote speed control (0 – 20mA) provides flexible adjustment of fan output.

Part of Vent-Axia’s eDemand controller range, the 2.5A inverter supports both single and three-phase applications and includes an integrated sine filter to ensure smooth motor operation. All models in the range offer a unified user interface and are compatible with IP54-rated twin fan auto changeover panels equipped with adjustable duty share timers.
