DESCRIPTION
SMA 2750 SERIES are designed to provide sufficient buoyancy to turn an unconscious person face upwards within 5 seconds
of immersion. Most adults require less than 5kg of flotation to keep their heads above water. However, this PFD will provide a
minimum buoyant force of 28.3kg (278 Newtons) when it is fully inflated.
SMA2750 is very light weight without the harness and other attachments. However, the Essential Services model such as the
Victorian CFA, Coast Guard & Melbourne Metropolitan Fire Brigade etc. has additional attachments such as the harness, J
knife and a detachable pocket containing a sewed on lifeline. Both ends of the lifeline have Makefast snap hooks and it weighs
about 510g. The total weight of the SMA275 model is approximately 2.28 kg
SMA2750 will fit teenager & adult with a chest range of 75 – 140 cm & weighing 40kg and above comfortably. It is designed to
be worn over outer clothing and is secured to the body with an adjustable waist belt system which also provides maximum
freedom of movement.
SMA2750 – MODELS, DESIGN & CONSTRUCTION
Models
There are 2 models of SMA2750, namely:-
-
Manual Inflation System (SMA2751)
-
Automatic Inflation System( SMA2752)
The difference between them is that the SMA 2752 is a manual type with an automatic backup inflation. In other
words, if you opt to use your PFD as a manual, you need to remove the automatic cartridge. With the automatic
cartridge screwed onto the inflator, your PFD will inflate when the cartridge is immersed in water. All other
features are the same for both models.
