Gast Vacuum Pumps & Air Compressors : Highly rated inexpensive aeration pumps

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 compressrs 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! 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 bubble tubing needs only 0.05 CFM per linear foot which is why the superior airflow from these compressors is perfect. We can provide larger compressors up to 40 CFM that can provide 15 PSI - 22 PSI Contact us

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.

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!

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 lifespan. 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 thermal overload protection which protects the motor from over-heating, the air filter, inlet check valve and power cord is included. 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 turn-key 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, de-icing 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 thatall 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.

Add diffusers & weighted airline and you've got a homemade, diy aeration system! Check the number of diffusers you need and choose the appropriate pump that can deliver the correct CFM. Measure the distance from the compressor to the diffusers and you have the length of weighted tubing needed. A few extra parts depending on your installation can be bought at your local plumbing supply store and you can save even more money!
