What is a Linear Actuator in a Fog Curtain System?

A linear actuator is an electromechanical device that converts rotational motion into straight-line movement.

Location

The actuator is typically installed:

Between the support structure and the fog curtain nozzle frame

Primary Functions

  • Raise the fog curtain assembly
  • Lower the nozzle frame
  • Adjust spray angle and coverage
  • Enable automated operation
  • Support sensor-based positioning

How Fog Curtain Systems Work

Step 1: Detection

Sensors detect dust levels, vehicle movement, or environmental conditions.

Step 2: Control Signal

The PLC or controller sends a signal to the linear actuator.

Step 3: Position Adjustment

The actuator raises or lowers the nozzle frame.

Step 4: Mist Generation

High-pressure nozzles create ultra-fine water droplets.

Step 5: Dust Suppression

Dust particles combine with water droplets and settle quickly.
