The Vent-Axia 10314307A is a 7 Amp three-phase 5‑step auto transformer, designed to regulate the speed of compatible fans in industrial and commercial settings. Featuring a robust IP54-rated enclosure, it ensures protection against dust and water ingress, making it suitable for harsh environments.
This unit allows manual speed adjustment through a rotary switch offering On/Off control and five stepped fan speeds. It helps eliminate motor noise and vibration, providing quiet, smooth operation without electronic hum.
For three-phase systems operating at 415V/3PH/50Hz, the controller outputs are 0, 65, 110, 175, 285, and 415 volts. A neon indicator provides clear operational status, and integrated terminals support remote On/Off switching.
Capable of controlling multiple fans, it supports multi-unit configurations as long as the total load stays within 90% of the controller’s maximum rated current. For safety, fan thermal contacts (TKs) must be wired in series.
Ideal for applications demanding reliable and noise-free fan speed control.
