Compressor Placement
It is critical that the air compressors be protected from the weather. You will
need to provide a shelter for your compressor to protect it from rain, snow and
other harsh elements.
• Be sure your shelter is adequately ventilated. A cooling fan may be neces-
sary in warmer climates. Several cabinet options with fans are available.
• Be sure the compressor does not sit directly on the ground, as the vibration
from the motor will cause dust and dirt particles to be pulled into the motor
and may cause premature failure.
• If operating compressor in freezing climates do not place compressor in
“heated” buildings. Warm air holds more moisture. This warm air may con-
densate and freeze in the colder outdoor line.
• Ensure that compressors are placed where
they will not become flooded with water.
• If possible, shaded areas are preferred.
• In areas with limited electrical supply,
compressors can be placed long distances
from the pond edge. A remote access valve
assembly can be fed from the compressor
with properly sized tubing.
Cabinet Placement
• If installing a Sentinel Deluxe Aeration System, place the cabinet on a level,
unobstructed base to ensure the compressor does not overheat.
• A post mounted cabinet should be kept free from high weeds and other
obstructions to ventilation system.
Diffuser Placement
The amount of surface area an aeration system will effectively cover is greatly
dependent on two factors - DEPTH and SHAPE. The deeper an air diffuser is
located, the more boiling action it will create and a larger area will be aerated.
The diagram below shows how much surface area is effectively aerated per
air diffuser at various depths. Ponds that are irregular or odd shaped will also
reduce size of aeration area — call our technical department for additional help.
Example:
Our PA34 pond aerator
would aerate only
1
/
8
of an acre if operated
in 4' deep water, while
aerating up to 1 acre
if operating in 12' - 16'
deep water.
The shape of a pond affects
the amount of diffusers
needed. Irregular shaped
ponds often require multiple
diffusers to adequately aerate
entire water column.
