Whenever I am
sizing an aeration system I usually look for a few basic parameters to help
me choose the best air compressor or air pump for the job. There are three
main types of compressors that are used for airation in ponds and lakes:
linear compressors, rotary vane compressors and piston compressors.
Rotary
vane air pumps and air compressors can provide a high volume/airflow
with medium pressure ranges of 5 PSI to 15 PSI Ideal for providing
air to diffusers for pond aeration systems with bottom mounted diffusers
at a 8 to 15 foot depth. The benefit of using the carbon vaned compressor
is that the motors will last for years with only a simple maintenance
change of the vanes.
These pumps are
quiet and have replaceable carbon vanes that are sacrificial so you
only need to replace the carbon vanes every 12 to 24 months and your
system can last for years, even decades with only minor parts replacements!
Let's look at the best compressors and air pumps to use for aeration.
The rotary vane system works extremely well in ponds with depths up
to 20 feet, the average carbon vane system will operate a multiple
diffuser system in fairly deep ponds and I have installed some larger
5 and 10 Horsepower compressors that can provide up to 22 PSI; the
key is to understand and apply the high CFM (cubic feet per minute)
airflow that these pumps are renowned for and ensure you use the correct
pipe diameter and airhose and feeder line to minimize pressure loss
and back pressure.
Of course a
tiny linear compressor will work well with two diffusers placed
in 6 feet of water but a solid rotary vane compressor can provide
the CFM to feed two to 5 diffusers. The 1/4 HP compressors will
provide 3.6 CFM to 4.0 CFM and the larger 1 HP pump will provide
11.8 CFM. A 5 HP compressor can offer 40 CFM of airflow! It's not
rocket science as long as you use the correct plumbing and airline
to divert and control the airflow!

Rotary Vane Pumps
These
motor-mounted, oilless rotary vane compressors are compact,
easy-to-service and excellent for moderate-pressure, continuous-duty
applications.
They more than double the air output of piston compressors with
better longevity. Sacrificial oilless carbon vanes automatically
adjust as they wear to maintain efficiency. Thermal overload
protection, air filter, inlet check valve and 8' power cord
is included. More

A small rotary
vane compressor can provide oil free air to multiple diffusers,
airstones, diffuser assemblies or diffuser tubing. A single small
efficient diffuser requires maybe 0.05 CFM and the large assemblies
maybe 2 or 4 CFM and some diffuser diffuser line, de-icing hose
or bubbler line needs only 0.05 CFM per linear foot which is why
the superior airflow from these compressors is perfect. We can provide
larger compressors from 10 CFM up to 100 CFM and that can provide
10 PSI - 22 PSI
Because
the number of diffusers required for the pond size depends on the
size of the pond I first have to know the length and width and depth
of the pond, this is they key to choosing the best air supply to build
an efficient aeration system for a pond or lake. We want to circulate
the total volume of water in a certain time period and in smaller
ponds we calculate the pond volume circulation so that it is circulated
every 6 to 12 hours.
When I step out in the back field and see a large 1/2 acre pond that
is 12 feet deep and fairly round I don't expect to be able to circulate
the entire volume within half a day...heck that isn't always necessary
in a natural earth pond because it's not a lined little bowl supported
by bricks and hedges! A large natural 1/2 acre pond can often use
just one or two diffusers to do the job but this is when the CFM of
the air pump is critical which is why I am so inclined to lean towards
a rotary vane system!

Why Choose Rotary
Vane Pumps For Aeration
After many years of building my own do it yourself aeration systems
I have worked out a simple calculator to help me decide quickly what
is the cheapest and most effective circulation and aeration system
for the pond:
We recommend
the use of motor-mounted, oilless rotary vane compressors that are
compact, easy-to-service and excellent for moderate-pressure, continuous-duty
applications. The compressors we use for airation provide more than
double the air output of piston compressors with better longevity.
The sacrificial oilless carbon vanes automatically adjust as they
wear out evenly to maintain efficiency throughout their 9 to 24 operating
vane life span Changing the vanes is simple; if you ask: how do I
change the vanes in a rotary vane compressor you will see that is
is very simple!
The only
wearing parts on these tough pumps is the replaceable carbon vanes.
Vanes last on average for 18 months of continuous usage. Buy a few
extra vane kits to ensure many years of faithful and trouble-free
usage. Full instructions for changing the carbon vanes are included.
Includes the gasket/seal, which should be replaced, that fits between
the motor housing and motor cap. Requires no special tools, heck,
even my brother once changed a set using only a penknife and a can
of beer!!
Ten-PSI
models work to a depth of 18 feet and 15-PSI models work to 27 feet,
depending on tubing diameter and distances between the pump and the
diffuser assembly. We create turnkey aeration systems using the 3/4HP
or 1 HP or 1.5 HP in single or multiple configurations depending on
he requirements of your diffusers or aeration tubing.
The vane compressors
are ideal because they can provide high CFM airflow through many airlines.
The typical diffuser system requires 2 to 5 CFM for correct operation
and we can provide multiple compressors in lockable steels cabinets
to operate and function throughout any seasonal conditions including
winter pond aeration, deicing or year-round aeration systems..
Unlike piston compressors, like the WOB-L piston compressor,the only
wearing parts in the rotary vane compressor are the carbon vanes,
which can be easily replaced in about 15 minutes using common tools
(in continuous operation, vanes last 9 to 18 months, depending on
the system operating pressure).
The rotary vane compressors you should use must be performance tested
and covered by at least one-year warranty (any manufacturer warranty
will provide a warranty that does not include air filters, vanes,
water damage or lightning damage).
The best thing about these air compressors is that all models can
be rewired in the field so they can accept 110V or 120 Volts or 230
or 240 Volts in either single or triple phase power and of course
it's best if you specify required voltage when ordering, so we can
supply the correct power cord (all single-phase models will be wired
115V if not specified).
Check valves are recommended where long underwater runs of air tubing
can fill with water when the compressor is off.

There are many turnkey, plug and play aeration systems on the market
that use a rotary vane compressor as the heart of the system. Of course
many of our clients prefer to buy an aeration system with a silent
and reliable compressor system and so when comparing aeration systems
that use rotary vane pumps it is worthwhile to compare the deference
between models and makes. There are many forums and reviews sites
that discuss the pros and cons of various pond air pumps but most
will agree that the carbon vane system is very efficient for providing
medium PSI and CFM for low cost.
You can expect to have 4.0 CFM and 11.8 CFM for each compressor with
operating pressures up to 15 PSI making these compressors one of the
most preferred systems!
Ideal for those of you who say "I want to build my own airation
system"! Of course the brand name aeration systems Like Gast
Compressors or Thomas Compressors or systems by Vertex from Aquatic
Systems or AquaMaster can offer ventilated cabinets to wrap around
the compressor you can also buy a cheap air pump and make your own
aeration system using plumbing parts that will fit the pump.
We like to compare by using the many years of our experience we've
had and direct you to the top-performing rotary vane systems and diffuser
assemblies and systems so that when you do start building an aeration
system you will be using the best components! You can build an aeration
system that performs as good as or better than the following systems
that utilize the rotary vane technology as the heart of their systems.

Rotary Vane Compressors AerationSupply.com oilless rotary vane pond
aerator compressors are compact, easy-to-service and an excellent
choice for moderate-pressure applications. All of our rotary vane
pond aerator compressors are designed for continuous-duty operation.
These rotary vane aeration compressors are the choice for many of
our pond aeration systems because they MORE THAN DOUBLE! the air output
of piston compressors and offer better longevity. One of the advantagious
design features of this type of pond aeration compressor is the internal
carbon vanes automatically adjust as they wear to maintain aeration
compressor efficiency. It is not unusual to have to change the vanes
about every 12 to 18 months if you operate the compressor continuously.
Each of our rotary vane compressors also offer: thermal overload protection,
air filter, inlet check valve and 7' power cord which is included.
Our 1/4-hp and 3/4-hp pond aerator compressors have a maximum operating
pressure of (10)-psi. The 1-hp rotary vane has a maximum operating
pressure of (15) psi. Before we ship in stock pond aerator compressors
each is performance tested. All rotary vane compressors are covered
by a one-year manufactuer's warranty (not including air filters, vanes,
water damage or lightning damage). AerationSupply.com pre-wires all

ROTARY VANE KITS
These rotary vane air compressor kits pump considerably more
air than the pumps above. Rotary vane pumps do not operate as deep
as the diaphragm and piston pumps — maximum operating depth is 18'.
A 3/4 HP high pressure model is available which operates to a depth
of 27'. The 1/4 HP model pumps 4.2 CFM of air compared to 1.5 CFM
with the 1/4 HP piston compressor. This larger volume of air will
increase circulation and oxygen levels for faster cleaning of the
pond's bottom. The 1/4 HP rotary vane kit is recommended for ponds
from 1 to 2 acres, but often is used in ponds less than 1 acre if
high fish population, exceptionally poor water conditions or heavy
nutrient buildup exists. The 3/4 HP models are recommended for ponds
2 to 4 acres while the 1 HP is used in ponds larger than 3 acres.
