Sale price$9.99

Description

This 100mm Back Draft Shutter is designed to automatically close off ducting when your extraction fan stops, helping reduce unwanted backflow through your ventilation line. It’s a practical addition for smaller grow tents and compact ventilation setups using 100mm ducting.

Why you’ll like it

  • Helps prevent reverse airflow when fans are switched off (as stated)
  • Automatic close function supports more stable ventilation control
  • Useful for reducing drafts and unwanted air movement through ducting
  • Simple inline addition to standard duct runs

Best for

  • Grow tents/rooms with 100mm inline extraction systems
  • Ventilation lines where backflow affects temperature/humidity stability (general guidance)
  • Systems that cycle fans on/off (timers or controllers)
  • Compact HVAC-style ducting needing one-way airflow control

How to use

Install inline with 100mm ducting in the correct airflow direction, then secure with clamps or tape as needed. Ensure the shutter can open and close freely without obstruction.

  • Install in the correct direction of airflow (general guidance)
  • Support ducting so the shutter isn’t under strain
  • Check operation after install (opens with fan on, closes when off)
  • Inspect periodically and clean dust build-up if needed

  • Coco: Not applicable
  • Soil: Not applicable
  • Systems: 100mm ducting and inline fan ventilation systems
