Ceiling Fan Cuff for 100mm PVC Duct | CFC
Description
Description
Quelfire’s CFC Ceiling Fan Cuff prevents the spread of fire through plasterboard ceilings.
One Size: For 100mm ∅ PVC Duct
It has been tested for use on both single and double-skin plasterboard ceilings and is compatible with various ventilation systems.
The CFC Ceiling Fan Cuff features built-in spring clips, making it easy to install, especially for retrofit projects.
Its steel-shell outer contains a high-performance intumescent material that reacts when exposed to fire, forming a carbonaceous char.
This char effectively seals off the gap left by the melting service, preventing fire from spreading to the next compartment.
Standards & Approvals
Standards & Approvals
- Cut the plasterboard aperture to Ø135mm around the Ø100mm PVC duct spigot.
- Centralise the PVC duct spigot within the hole.
- From the underside push the Quelfire CFC up into the aperture around the PVC duct ensuring the spring clip clamps fully back onto the plasterboard and that the Quelfire CFC is clamped tight in position.
- Make sure the gap between the CFC and the plasterboard is clean of any debris and remove dust from all edges.
- Seal the small gap between the CFC and the plasterboard and around the power cable with QuelStop Intumescent Acrylic Sealant.
- Install the ceiling fan to the plasterboard with correct screw fixings in accordance with the ceiling fan manufacturers requirements.

Product Info & Features
Product Information
| Property | Details |
|---|---|
| Composition | The CFC Ceiling Fan Cuffs consist of a continuous pressed stainless steel flexible shell containing a high-performance graphite-based intumescent material. This material reacts under the influence of heat to exert pressure on the duct as it softens, forming a carbonaceous char that acts as an effective insulation plug, preventing fire from passing through to the adjoining compartment. The CFC has built-in spring clips which securely hold it to the plasterboard ceiling. |
| Testing & Installation Responsibility | The CFC has been tested in the scenario shown on specific manufacturers’ fan units. However, the customer/installer is responsible for ensuring suitability. Installers should verify the product, test data available, standards to which the product is tested, fan units and ducting, and floor/ceiling construction meet their specific scenario. Quelfire is unable to provide guidance for all possible installations, so consulting a fire engineer is recommended for final suitability confirmation. |

-
Up to 90 minutes Integrity and Insulation.
-
Can be retrofitted.
-
Suitable for a range of ventilation systems.
-
Tested on both single and double skin plasterboard ceiling timber floors.
