Allvent ALVIFDS2020 500MM Square Intumescent Fire Damper

The Allvent ALVIFDS2020 ALV511 is a 500mm square intumescent fire damper designed for large 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 well suited to 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 practical installation.
