Intumescent air transfer grilles

Series LV 1

DescriptionKoolair LV intumescent grilles are used to compartmentalise zones inthe event of a fire or high temperature gases.

The LV grilles contain an intumescent material that expands in theevent of fire to seal the ventilation duct in accordance with BS 476:Part 20 and 22 and UNE-EN 1634-1:2000.

There are two models in the LV grille range, each with differentcharacteristics to allow the correct selection to be made depending onthe desired application.

The LVV40/LVC40 range with PVC coated sodium silicate grilles for walls, doors and both circular and rectangular ductwork.

The LVV40/LVC40 models provide 60 minutes of resistance in caseof fire or high temperature smoke (EI30/EI60) and the expansiontime for the intumescent material to seal the ventilation shaft isapproximately 5 minutes.

They are designed to facilitate without excessive noise and efficient airflow. They allow air to flow in both directions through the grille and can be mounted both vertically and horizontally depending on the application. They have a free area of approximately 60%.

They are designed to be easily installed, contain no moving partsand are maintenance free and resistant to clogging.

The grilles in the LVH44/LVHC44 range are high performance grilles,designed for use in aggressive work environments. They are made of graphite lined aluminum with protected edges of steel metallic structure and designed for applications in walls, doors, floors,ceilings and both circular and rectangular ventilation ductwork. Theyare suitable for outdoor use and can be mounted both vertically andhorizontally.

The LVH44/LVHC44 models provide 120 minutes of resistance incase of fire and high temperature smoke (EI90/EI120) and theexpansion time for the intumescent material to seal the ventilationshaft is approximately 2 minutes. They are designed without excessive noise and efficient airflow at normal and high air flow rates. They have a free area of approximately 60%.

They have a steel frame that protects the intumescent material fromany deformations that may occur in the grille housing structure.Likewise, in these models, the metal frame that protects theintumescent material prevents it from deteriorating as a result of hot,corrosive or high velocity air passing through.They contain no moving parts and are low maintenance andresistant to vibration damage.
