Astro DS duct sleeves are intended for use where a ventilation duct passes through a fire rated wall. The sleeve maintains the integrity of the fire rated wall which would otherwise be lost.

In the event of a fire, the advanced Astro DS Duct Sleeve will expand with the heat, crushing the duct and closing off the hole to the fire for at least 60 minutes..

The Ventilation duct sleeves are available to fit all common sizes of plastic ventilation duct and are suitable for retro fitting with access only required from one side.

NOTE: Three sided installation, where the top of the duct sleeve is cut away to give a flush fit under a ceiling soffit, is not possible with this (220x90 mm) version.


The 60 minute version is only available in one size:
