Application

Suitable for doors. In applications where high levels of humidity or wetness are anticipated, it is recommended that an LVH44 product should be employed.

Description

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.
