The exclusive mount for air pump installation made of concrete should be
arranged. The mount should be away from the foundation and its height
should be min. 10 cm higher than the foundation.

vibration of the air pump mounted on an unstable place such as concrete blocks,
shelf etc.

of level will be partially applied on rubber parts, which may shorten the life of the

heavily, provide a roof to keep the air pump from the
slanting rain.
Water of slanting rain etc. taken in the air
pump will enter the part charged, which can be cause of
