always guarantees a minimum concentration of 25 % oxygen on mixtures which
includes nitrous oxide.
IN CASE OF LACK OR LOW OXYGEN PRESSURE CUT-OFF: audible alarm
with immediate cut-off of nitrous oxide delivery.
AGAINST OVERPRESSURE IN FLOWMETER BOX : safety valve calibrated at
0.8 bar for the protection of the glass rotameters.
IN CASE OF LACK OR COMPRESSED AIR LOW PRESSURE : all the devices
(gas feeding) supplied by compressed air are automatically supplied by oxygen.
AGAINST THE SIMULTANEOUS DELIVERY OF AIR AND N
membrane key on the flowmeter front panel.
