A J Services manufacture a wide range of fire
dampers which have been designed to be fitted into the ductwork
connected to a HVAC system. Fire and smoke dampers play a vital
role in the both commercial and residential buildings safety should
a heating, ventilation and air conditioning system be in place
which is attached to ducting, by preventing either/or both fire and
smoke from spreading further through the system. It is a legal
requirement to have fire and smoke dampers in place in a commercial
buildings in many instances, and where they are they are required
to undergo at a minimum yearly testing to ensure they are still in
working order. Fire dampers work because of an attached fusible
link, this link monitors the surrounding air temperature and once
it reached a pre-determined temperature the blades in the damper
will be forced shut and the fire contained in that area - where
they are able to withstand the fire from spreading for 2 hours. The
temperature is traditionally set to *2 degrees, although this can
be changed if needed.
The dampers can be used in either high or low velocity and
manufactured from galvanised steel, with the blades being housed in
rectangular/square casing. These can be fitted to both
circular/spiral tube ducting as well as rectangular. Whilst the
housing of the damper is rectangular the dampers can still be
fitted to spiral/circle ducting - this is achieved through the use
of a spigot which allows for immediate connection. Because of this
it means that the blades will also be out of airstream. The
rectangular options differ slightly to the circular, the blades can
either in or out of the airstream - there is also a range which can
internally in to the duct, rather than having walls built around
the damper. Both circular and rectangular dampers as standard are
supplied with hanging cleats or lugs so that they can be positioned
into place and remain securely in place. They can also have
additional frames added either a drywall/plasterboard or HEVAC
frame. Dampers manufactured by AJS start at *0mm and go up to a
maximum of ***0mm.
