Description

As smoke can spread rapidly and efficiently through a building ductwork system, damper operation needs to be initiated by a smoke detection system, as thermal sensing can often be too late. Hot/Shield PTC and Hot/Shield Vent PTC dampers are designed to be interfaced with a smoke detection/fire alarm system.

Actionair have developed the Hot/Shield PTC High Temperature Smoke Management and Fire Dampers along with the Hot/Shield Vent PTC Smoke Control and Extract Dampers to enable the concepts of fire engineering to be employed in ducted smoke ventilation systems. These dampers designed, tested and approved to deliver high temperature operation at up to 300 ?C for two hours, provide the designer with the capability of extracting hot smoke and combustion gases through a common smoke extraction duct linked to adjacent fire zones and floors.

Construction

Hot/Shield Vent PTC High Operating Temperature Smoke Control and Extract Dampers comprising of 75mm stainless steel aerodynamic blades incorporating synthetic seal, with stainless steel blade end bearings and peripheral gasketing. Housed in a galvanised fully welded, spigotted casing suitable for square, rectangular, circular or flat oval connections. The totally enclosed precise movement opposed blade drive shall be positioned out of the airstream for protection against damage, be hard wearing and free running. The Control Mode/Damper connection shall be by means of the snaplock drive interface mechanism, which is totally independent of the ductwork. Hot/Shield Vent PTC dampers and the in appropriate insulated control modes shall be arranged for motor close and spring open operation.
