DucoGrille Classic N 50HP

Application

Louvres for wall/ window ventilation.

Description

Recessed wall or window louvres, manufactured from extruded aluminium profiles, developed especially for intensive ventilation. The resistance factor of both systems is exceptionally low which allows large quantities of air to be introduced into or removed from spaces, using only a limited surface. Visual free area amounts to 88%, physical free area 68%.


Features and benefits:

  • The Turn and Click system ensures quick and easy assembly.
  • Many louvre blade options are available.
  • An insect screen is fitted as standard.

WarrantyDescription

Ten year

Duco Projects provides 10-year warranty cover on Duco system materials covering potential defects in materials and surface treatment, applicable from the date 3 months after delivery or from the date of installation, whichever is the sooner.For motors and for components subject to wear as a result of movement, however, this warranty is limited to 1 year. This warranty is only valid for building projects in European countries (other countries upon request only) and provided normal use and maintenance have been observed. This warranty is on a sliding scale, reducing by 10% a year (e.g.: during the third year 80% of the claim will still be covered by this warranty). This warranty covers the supply of replacement parts on site to be fitted by the installer, or in the event of defective surface treatment, substantiated costs for pre-treating and recoating the material in question. This warranty relates exclusively to the product itself, not to its installation: accordingly, dismantling and assembly costs are not covered by this warranty. Duco Projects’ maximum liability will be exhausted with the resupply of the defective component or complete system. Under no circumstances can Duco Projects be held liable for any other tangible or intangible loss, including consequential losses. A repaired or resupplied product is covered for the remainder of the warranty period.
