Description

A high performance, standard vision intumescent air transfer grille for doors, walls and ducts.


Features and benefits:

  • The design allows space savings, ease of installation and avoids the need for operational function checks.

  • Fits directly into ducts, doors or wall apertures.
  • No moving parts.
  • Excellent fire integrity and insulation performance.
  • Not prone to clogging.
  • No access panels required.
  • No moving parts.
  • Robust construction.
  • No maintenance.
  • Use with metal cover grille (optional).
  • Other non-standard sizes may be available - consult the manufacturer for details.
  • Performance: Can be used to provide up to 60 minutes resistance to fire. EI rating of 120 minutes when used in conjunction with a cover grille. Consult the manufacturer's Technical Department for details.
  • Orientation: LVC40 products can be installed either vertically or up to 300 mm diameter horizontally.
  • Positional requirements (Certifire):The upper edge of the grille shall be no higher than 3000 mm from floor level. The lower edge of the grille shall be no closer than 400 mm to floor level.
  • Free area: Low sound power level +.
  • Fixing: 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 mm diameter nominal size damper will suit a 200 mm diameter aperture. Screwed and bedded in Lorient intumescent sealant.
