Materials and surfaces

Casing:

• Galvanised sheet steel
• Galvanised sheet steel, powder-coated RAL 7001
• Stainless steel 1.4301

Damper blade:

• Special insulation material
• Special insulation material with coating

Other components:

• Damper blade shaft made of galvanised steel or stainless steel

• Seals of elastomer

The construction variants with stainless steel or powder-coated casing meet even more critical requirements for corrosion protection. Detailed listing on request.

Standards and guidelines

• Construction Products Regulation
• EN 15650:2010 Ventilation for buildings – Fire dampers
• EN 1366-2:1999 Fire resistance tests for service installations – Fire dampers
• EN 13501-3:2010 Fire classification of construction products and building elements
• EN 1751:1999 Ventilation for buildings – Air terminal devices

Maintenance

• The functional reliability of the fire damper must be tested at least every six months; this has to be arranged by the owner of the ventilation system; functional tests must be carried out in compliance with the basic maintenance principles stated in EN 13306 and DIN 31051. If two consecutive tests, one 6 months after the other, are successful, the next test can be conducted one year later.
• A functional test involves closing the damper blade and opening it again; with a spring return actuator this can be done via remote control
• Fire dampers must be included in the regular cleaning schedule of the ventilation system.
• For details on maintenance and inspection refer to the installation and operating manual
