Pneumatic Tubing Requirements
Protective Gas Supply Requirements
The protective gas supply to the protection system must be
a clean, instrument quality compressed air or nitrogen and
must contain no more than trace amounts of flammable gas,
vapor or dust.
The protective gas supply compressor intake must originate
in a nonhazardous location. Suction duct passing through a
hazardous location and the protection system tubing and
piping must be fabricated from noncombustible materials
suitable for prevailing hazards and environmental conditions.
The protective gas supply must originate from a dedicated
instrument quality compressed air header (1/2" pipe or
larger), no farther than twenty (20) feet from the protection
system. Local compressors and gas cylinders should not be
used before consulting with Fuchs.
The protective gas supply to the protection system must be
equipped with a tamper-proof regulator set at 5 psi maximum.
Exception:
If the protected enclosure(s) is equipped with an
EPV-3 Enclosure Protection Vent, the protective gas supply
to the protection system must not exceed 120 psi maximum,
5 psi minimum.
