SPIROLINE BELT
The Spiroline belt consists of a coupling with four connections mounted on a belt
with a waist buckle. The hose to the facemask is connected as shown below. One
connection is used as a compressed air input and is connected to the P+ regulator. In
this connection there is a check valve to prevent toxic gases from getting in if the air
supply hose is disconnected. The two other connections are fitted with blank plugs or
the optional pressure gauge and the optional suit ventilation hose; see figure below.
