Ex e mb, Ex d mb, Ex mb, Ex ia for zones 1 & 2
(gas), 21 & 22 (dust), ATEX cat. II 2GD
International approvals: IEC Ex, FM, CSA
Medium:
Filtered, non-lubricated and dried
compressed air, instrument air,
nitrogen and other non-flammable
neutral, dry fluids
Operating pressure:
2,5 ... 8 bar (36 ... 116 psi)
with internal air supply
0 ... 8 bar (0 ... 116 psi)
with external air supply
Ambient temperature:
-40 ... +65°C (SNBR)

Depending on solenoid system.
Air supply must be dry enough to avoid
ice formation at temperatures below +2°C
(+35°F).
For outdoor installations all
connections must be protected
against the penetration of
moisture and a solenoid with IP66
protection must be used!
