The Isomax Acoustic Inline Extraction Fan combines air extraction and acoustic insulation in one unit. It is designed for indoor growing spaces where reducing ventilation noise matters, without needing a separate silencer box around the fan.

How It Works

A rotor-stator system moves air through a full-metal housing lined with soundproof foam. The integrated acoustic lining helps reduce fan noise while the unit extracts air from your growing space.

Key Features

  • Fan and acoustic insulation combined in one unit
  • Full-metal housing with internal soundproof foam lining
  • Speed controller included with 150mm and 200mm models
  • Choose duct diameters from 150mm to 355mm
  • Seven airflow options to suit different ventilation requirements

Available Models

  • 150mm (6 inch): 410 m³/h
  • 200mm (8 inch): 870 m³/h
  • 250mm (10 inch): 1,480 or 2,310 m³/h
  • 315mm (12 inch): 2,380 or 3,260 m³/h
  • 355mm (14 inch): 4,800 m³/h

Choosing Your Fan

Match the duct connection and airflow requirement to your setup. Allow for resistance from carbon filters, ducting and bends, which can reduce installed airflow. Check the selected model's requirements before choosing a compatible filter or external speed controller.

Ideal For

Grow tents, indoor gardening rooms and other cultivation spaces where quieter extraction is a priority.
