Design & Construction
SMA 2750 is basically made up of a bladder enclosed in a valise. The bladder is made from polyurethane coated
materials .However the valise is made from flame safe fabric called Nomex.
The bladder has the following items on
-
60gm co2 gas cylinder inflation mechanism with the pull toggle( Tab);
-
Oral inflation tube ;
-
Whistle;
-
Water activated rescue light which serves as a beacon for an emergency rescue situation ( optional
feature);
-
60cm of SOLAS Grade reflective tapes appropriately distributed on the front side of the bladder;
-
A collar strap.-
-
For SMA2752, automatic cartridge.
The front of the bladder has indelible donning & operating instructions. The back of the bladder contains care
instructions, warning alerts and a service record section.
The valise is not part of the inflation system but acts as a protective covering and as an enclosure for the bladder
when it is deflated by sealing the Velcro fastener which is sewn along the side edges. A small protruding tab at
the bottom right hand side of the valise is used
to assist in opening the valise to inspect or service the
bladder inflation system
(see fig 1). The valise also houses the adjustable waist belt system but the latter can
be detached from the bladder. Like the bladder, there are donning, operating instructions markings. It also has a
marking to identify whether the PFD is a manual or an automatic model.
The waist belt is made out of durable polyester material and is fastened using a stainless steel buckle and an
adjustable mechanism. Provision is made for excess belt to be tucked away after fastening without any physical
hindrance. The waist belt also has provision for a J knife and a detachable pocket that houses a lifeline.
Both models have a harness sewed onto the valise and is integrated into the waist belt system
RECOMMENDATION:
We strongly recommend that you initially buy 2 re-arming kits for your respective model, one for initial
familiarisation and the other to serve as a spare.
We also recommend that you routinely check your PFD as instructed below. If you are not confident, please send
it to Roaring Forties authorised service agent to attend to your PFD.
TO OPERATE SMA 2750
By jerking the pull toggle of the 60g carbon dioxide gas inflation system, the PFD will inflate. This is for both models. However,
for the automatic model, the PFD will inflate when the automatic cartridge is immersed in water. Hence there is choice for the
automatic model.
