l Back to AC Motor Fan Control Home Page l V-Series l B-Series l N-Series l


The VariPhase V Series AC fan speed control is capable of 115V, 230V, 277V operation. Current handling from 3 amperes to 20 amperes from a single unit.

V-Series AC fan speed controls are full feature: Open loop or closed-loop control; Network or Analog input; 3-wire or 2-wire operation; Soft-start and selectable minimum speed pot etc. V-Series offers the most flexible options for single-phase speed control.

AirCare VariPhaseTM has network connectivity (MODBUS RTU-based) through RJ45 to any controller or AirCare's’ Proprietary Control System. Analog Control input allows manual control or analog inputs from any PLC or system controller.

Main Features

  • Low Cost Digital Control (MODBUS-RTU) Network
  • Full PID control loop (closed loop)
  • “Cluster” (multi-fan) control
  • Analog Input
  • Soft-Start
  • Linear Control of fan speed (RPM)
  • Closed loop by analog feedback/tach

Target Applications

  • Cleanroom
  • Mini-Environment
  • Hospital
  • Ventilation
