1.9 OPTIONAL CYLINDER QUICK COUPLING
The SCBA can be equipped with a cylinder quick coupling as an option. The
regulator unit is then connected to the cylinder valve by simply pushing them together.
When the SCBA is pressurised the quick coupling is locked and not possible to
disconnect. With the SCBA evacuated of air the quick coupling can be disconnected
by pushing the locking ring and then removing the regulator unit from the cylinder
valve.
The quick coupling ts 4500 psi cylinders with the use of an adaptor on the cylinder
valve. The adapter is installed on the cylinder valve with a torque of 40 Nm (29.5 lb
ft).
Cylinders with the adapter can be re-lled without removing the adapter. Interspiro
offers a quick connect cylinder charging adapter, p/n 31602-01, for existing ll
hoses.
If the adapter is removed the cylinder can be lled with a standard ll hose.
