Product Features

Our market-leading UK smoke and fire dampers will fit most circular ducting in the UK. Manufactured in the UK, the smoke and fire damper is ES-rated in accordance with EN 13501-3 and fully compliant with product standard EN 15650:2010. They are available in sizes between 100mm and 355mm for both 24V and 230V systems.

The CSS range of ES-rated dampers has been developed to provide effective control of fire and smoke. The purpose is to reduce the spread throughout a building via ductwork to aid the escape of those in the building and to provide easier firefighting access, reducing the risk to people and property.

Suitable for standard circular/spiral ductwork systems, this allows heating, ventilation and air conditioning (HVAC) systems to circulate air in normal conditions but automatically shuts when a fire breaks out. This means the fire rating of your walls and ceilings are not compromised, stopping smoke and fire for up to two hours.

How Does The Smoke And Fire Damper Work?

CSS dampers feature a single stainless steel blade which drops into position to create a smoke and fire barrier. This is automatically activated when the electrical thermal release breaks when it reaches 72°C. The damper also has an inbuilt fail-safe which ensures the shutter closes should the power supply be interrupted, just in case.

Requiring installation by a trained engineer, the damper is suitable for most wall, floor and ceiling types of rigid construction (drywall, masonry, block work and concrete). The Actuator, which operates the damper, is supplied fitted and the control mode should be wired into the HVAC system.

Inspection and Maintenance

Each damper has a green LED lamp built in, as standard. This gives the user a simple and clear visual check that the Actuator is receiving power, the Electrical Thermal Release is correctly fitted, and the thermal fuse is intact. Plus, it features a manual test switch to check the fail-safe release under smoke and fire conditions.

Regular inspection, maintenance and cleaning of your dampers are essential, in line with the entire ducting system, which is undertaken by a qualified engineer as part of the requirements of BS 9999. As such, you must ensure adequate access is provided to fire and smoke dampers with access panels and doors.

Selecting The Right ES-Rated Damper

CSS Dampers are designed for applications in normal dry filtered air systems, and suitable for standard or 50mm insulated circular ductwork. Firstly, you need to ensure you select the power voltage which is compatible with your existing HVAC system, either AC/DV 24V or AV 230V.

Secondly, when selecting the size, this relates to the diameter of the ducting. With sizes available to suit most systems, every size is fully compliant to the relevant standards.

Approvals

Manufactured in the UK by market-leaders Actionair, they’re ISO9001 and ISO14001 accredited, producing dampers which are CE Marked and are an LPCB approved product.

Fully compliant with product standard EN 15650:2010, the smoke and fire damper is ES-rated in accordance with EN 13501-3, corrosion tested to EN 60068-2-52, thermal fused tested to ISO 10294-4, and fire tested to EN 1366-2. Plus, every damper undergoes a continuous program of cyclic and leakage testing to ensure quality.

Please Note: Due to their specialist nature, the circular smoke and fire damper is not available on our standard next working service. Please expect delivery within 5-8 working days.
