Inline Butterfly Damper 150mm Baffle

Description

150mm Inline Butterfly Damper

Improve the efficiency of your ventilation system with the 150mm Inline Butterfly Damper. Designed to prevent backdrafts, this damper stops outside air from flowing back into your ducting when your rangehood or exhaust fan is switched off.

Constructed from durable galvanised steel, it features two spring-loaded aluminium dampers that open with airflow and close automatically when the fan stops. A built-in foam ring provides a secure seal while reducing noise for quieter operation.

The damper is designed to fit neatly inside 150mm ducting and is compatible with both flexible foil ducting and semi-rigid ducting. Installation is quick and easy using worm clamps and/or duct tape.
