Humidistat Extractor Fan with Pull Cord

Automatic Moisture-Controlled Ventilation

The Humidistat Extractor Fan provides effective mechanical ventilation for bathrooms, toilets, shower rooms, kitchens, utility rooms and other non-habitable domestic spaces. Its built-in adjustable humidistat responds to moisture levels, helping to reduce condensation, dampness and the conditions that encourage mould growth.

Available in 4-inch and 6-inch sizes, the fan combines automatic humidity control with convenient pull-cord operation. Both models are suitable for direct through-wall ventilation or short ducting runs of up to 1 metre.

  • Built-in adjustable humidistat responds to moisture levels
  • Helps remove humid air, excess moisture and unwanted odours
  • Supports the control of condensation, dampness and mould growth
  • Pull-cord operation provides convenient local control
  • Available in 4-inch and 6-inch sizes
  • IP44-rated protection
  • Suitable for direct through-wall ventilation
  • Can be used with short ducting runs of up to 1 metre
