Allvent ALVIFDS1818 450MM Square Intumescent Fire Damper

The Allvent ALVIFDS1818 ALV510 is a 450mm square intumescent fire damper designed for larger ventilation openings through fire-rated walls and floors. Its rigid steel-framed grille allows normal airflow through the ventilation system, while the intumescent material expands under fire conditions to form a fire-stop barrier. With up to 2 hours of fire protection and no moving parts that require operational checks, it is a practical choice for commercial, multi-residential and larger building ventilation systems where maintaining the integrity of fire-rated construction is essential. It can also be fitted into steel ducting for a secure and straightforward installation.
