Material and surfaces
Casing:

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

• Special insulation material
• Special insulation material with impregnation
• Replaceable damper blade (from NS 180 mm)
  
  

Other components:

The design variants made of stainless steel or with powdercoated casings meet increased requirements for corrosion protection. Detailed resistance lists upon request.

Supply package

If attachments and accessories are factory-mounted on the fire dampers, they are already included in the order code. Depending on the installation situation, additional materials such as mortar, screws or mineral wool may be required for correct installation. Such materials are not usually included in the supply package (unless stated otherwise). Attachments and accessories have to be selected by people in charge of the building project. These people also have to select and provide any additionally required installation or fixing materials and make sure that the required classifications are met.

• At the instigation of the owner of the ventilation system, the functional test of the fire damper must be carried out at least every six months, taking into account the basic maintenance measures in accordance with DIN EN 13306 in conjunction with DIN EN 31051. If two consecutive tests, one six 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 function can be done via a remote control
• Fire dampers must be included in the regular cleaning schedule for the ventilation system.
• For details on functional tests, maintenance and inspection refer to the operating and installation manual

• The fire damper is used as an automatic shut-off device to prevent fire and smoke from spreading through the air duct
• The fire damper is suitable for supply and extract air in ventilation and air conditioning systems
• The fire damper may be used in areas with potentially explosive atmospheres if suitable special accessories are used and if the product bears the CE conformity marking according to Directive 2014/34/EU. Fire dampers for use in areas with potentially explosive atmospheres are marked for the zones for which they have been approved
• Operation of fire dampers is allowed only in compliance with installation regulations and the technical data in the installation and operating manual

• Do not use in extract air systems in commercial kitchens
• Use as an air transfer damper (MFD) only in accordance with General construction technique permit Z-6.50-2516
• Use with a combined penetration seal requires projectrelated type-approval.
