Standards and guidelines

  • Construction Products Regulation
  • EN 15650 Ventilation for buildings – Fire dampers
  • EN 1366-2 Fire resistance tests for service installations – Fire dampers
  • EN 13501-3 Fire classification of construction products and building elements
  • EN 1751 Ventilation for buildings – Air terminal devices
  • 2006/42/EC – Machinery Directive


Supply package

If attachments and accessories are supplied from the factory with the fire dampers, they are already taken into account in the order code. Depending on the installation situation, supplementary materials for assembly and fixing may be needed to ensure proper installation, e.g. mortar, screws, mineral wool, etc. Such materials are not included in the supply package, unless they are expressly described as included in the supply package. The selection of additional attachments or accessories as well as the identification and provision of materials for assembly and fixing is the responsibility of those involved in the building project and must be done taking into account the required classification.



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 2 consecutive tests, one 6 months after the other, are successful, the next test on the fire damper 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 for the ventilation system
  • For details on functional tests, maintenance and inspection refer to the installation and operating manual

Technical data

  • Nominal sizes: 315 to 800 mm
  • Casing lengths: 495 and 550 mm
  • Volume flow rate range: up to 6000 l/s / up to 21600 m³/h
  • Differential pressure range: up to 2000 Pa
  • Temperature range: -20 – 50 °C
  • Upstream velocity*: Standard construction ≤ 8 m/s, construction with spring return actuator ≤ 12 m/s, construction with explosion-proof actuator ExMax/RedMax-15-BF TR ≤ 10 m/s


* Data applies to uniform upstream and downstream conditions for the fire damper


Incorrect use

  • without specially approved attachments in areas with potentially explosive atmospheres
  • as a smoke control damper
  • outdoors without sufficient protection against the effects of weather
  • in atmospheres where chemical reactions, whether planned or unplanned, may cause damage to the fire damper or lead to corrosion


The following applies to Germany

  • Do not use it in extract air systems in commercial kitchens
  • Do not use it as an air transfer damper
  • Do not use in combined penetration seal
  • Do not use in fire protection block bulkhead.
  • Approvals under building regulations may be required for the use of upstream shutters of air transfer units. This must be checked and applied for by others.
  • Flame-resistant, non-dripping building materials (elastomeric foams) must at least correspond to fire rating class C - s2, d0 according to the specifications of MVV TB (since 2019/01). The applicable national building regulations must be adhered to
