LVN20 Intumescent Air Transfer Grille - Non-vision

A non-vision intumescent air transfer grille. Supplied in two pieces it lends itself to easy installation in a standard 44 mm-thick fire door and when finished with a colour coordinated edge flange, results in an attractive but efficient air transfer feature. Use with integral steel or aluminium flanges. No cover grille required.

Features and benefits:

• Louvred slats give privacy
• Bi-directional airflow
• No site testing necessary
• No moving parts
• Attractive facade on both sides
• Colour match available
• Easy to keep clean.
• Each air transfer grille is manufactured 2 mm less than a nominal aperture size to provide clearance when installed in a duct or other aperture of the same nominal dimensions. e.g. a 198 x 198 mm nominal size air transfer grille will suit a 200 x 200 mm aperture. Screwed and bedded in Lorient intumescent sealant.
• The upper edge of the grille shall be no higher than 800 mm from floor level.
• LVN20 is best suited in the vertical plane.
