Fire & Smoke Damper CFD-01 Description

Specification

The type CFD-01 Fire and Smoke damper has been designed for building into walls, floors or bolting or welding to steel bulkheads. The damper has been successfully tested in accordance with BS476 and IMO Resolution A754, and is certified by Lloyds Register of Shipping and DNV for A0, A60 and H120 rated divisions when suitably lagged. To ease installation these dampers can be supplied with pre insulated controls, and are designed to be suitable for mounting in any attitude with the airflow in either direction.

Casing

These dampers are also suitable for operation at 250°C for one hour for smoke clearance.

The damper casing is formed from 3.0 mm thick sheet steel into a rigid channel section to ensure proper alignment of blades and shafts. Damper Units in excess of 1000 mm width or height shall Be manufactured as a multiple assembly. Where circular dampers or dampers with width or height dimensions less than 150 mm are required, additional spigot adaptors are used which increase the damper insertion length from 300 to 400 mm.

Blades The blades are a formed double-skin aerofoil section of 1.5 mm sheet metal which operate on the ‘Firelock’ principle creating a 3-pass labyrinth between the blades which fire cannot penetrate. Blade stops at the top and bottom of the casing and sprung side seals provide excellent low leakage characteristics.

Shafts 300

Continuous Ø 19.05 mm with blades plug welded at each end.

Linkage Opposed action linkage consisting of drive levers and bosses connected by flat bar link bars, driven through stainless steel pins. All linkage is contained within the depth of the damper casing.

Bearings Phosphor bronze self lubricated ‘Oilite’ flanged bushes.
