„Neutral atmosphere“ relief wells
• When conveying and compressing „neutral gases“ such as ambient air, it must be
ensured that the connections of the relief wells are open to the atmosphere. These
relief wells are marked on the installation drawing as „neutral atmosphere“. If
these wells are closed by means of gas-tight screwed sealing plugs or other plugs,
for example, this will cause oil to leak in the compressor‘s conveying chamber.
• Danger of lubricating oil contamination in the medium to be conveyed !
• Due to the process by which the compressor is manufactured and/or the storage
time of the replacement compressor stages used, these wells may be sealed at
the factory with plastic plugs, stickers or similar.
• Please check these wells during first commissioning and remove any seals that
may be present.
• The relief wells are arranged around the circumference of the discharge-side and
intake-side seals, depending on the type used.
