What is Swan Aero-Tube™ aeration tubing made of?
Our patented Swan Aero-Tube™ aeration tubing is made using a special process that combines linear low density polyethylene and rubber from recycled car tires. Swan uses over ten million pounds of the rubber from recycled tires every year to make porous tubing.
Can you clean the tubing or do you have to replace it?
It is very simple to clean the tubing by using a gloved hand and clean water. Put the tubing in water and rub vigorously. After several years of continuous usage, the tubing should be replaced to maintain the maximum efficiency and oxygen exchange.
Is there a limit to the operation time for Swan’s aeration tubing?
No. Our aeration tubing product is designed to operate 24 hours a day/7 days a week without problems.
What is the maximum length of tubing I can use in a continuous run?
The tubing is most efficient if used in lengths of six feet or less. You can use longer lengths if you supply air at both ends. The key is to maintain an air flow as close to 0.4 CFM as possible throughout the length of the tubing.
Will Aero-Tube™ clog or become blocked preventing proper aeration?
Under proper operating conditions the tubing should not become blocked. It may clog if it is placed directly on the pond bottom, because it is designed to be suspended eight to ten inches off the bottom. Aero-Tube™ aeration tubing works best when run continuously but it can also be used intermittently as long as it is run regularly to clear out any potential contamination.
Why does Swan Aero-Tube™ transfer more oxygen than other technologies?
The answer is surface area. Swan’s fine bubble technology creates significantly more surface area than competing technologies resulting in a much higher oxygen transfer rate and a more efficient system.
How do aerators equipped with Swan’s Aero-Tube™ aeration tubing compare to other traditional aeration devices (e.g. paddle wheels)?
In a head to head comparison of the Aero-Tube™ aeration system against various paddle wheel systems, the Aero-Tube™ system was as much as 2.6 times more efficient in fresh water and 4.2 times more efficient in salt water. Our tubing puts the air directly into the water for absorption, by creating extremely fine bubbles. A paddle wheel merely throws the water up into the air for an exchange to take place, a much less efficient method of aeration.
Does an Aero-Tube™ air lift system provide vertical mixing and directional flow?
Yes. Because of the high volume of fine bubbles created by the tubing it can vertically mix very effectively. Due to the design of an Aero-Tube™ air lift system, a strong directional flow current is also produced with proper system design and setup.
Is there a warranty on Swan’s aeration tubing?
There is a limited warranty on our product. When used for its designed purpose, our aeration product has a warranty against defects in workmanship or materials.
Can I use a soaker hose as an aeration tube instead of Swan’s Aero-Tube™?
Yes, but we strongly discourage it for the following reasons: Soaker hose is typically made with a thinner wall and is therefore likely to have a shorter lifespan than Aero-Tube™ aeration tubing. Aero-Tube™ products are specifically designed to provide air flow efficiently and create a small-sized bubble. Soaker hoses have significantly fewer and larger pores than Aero-Tube™ tubing and thus will require higher air pressure to operate, resulting in higher energy costs.
Can I replace my air stones with Swan’s aeration tubing?
Yes. Swan’s aeration tube is more cost effective and efficient than air stones. The aeration tubing is not prone to breakage like air stones. It is also easier to clean. You simply rinse it with water, rather than the muriatic acid typically used to clean air stones.
What are the critical considerations when choosing a blower to supply air to Swan’s Aero-Tube™?
One of the most critical aspects in the design of an effective aeration system is choosing the proper size blower. A blower that is too large will most likely overheat from constant back-pressure, and will have a short life. And a blower that is too small will not deliver enough air to the system.
The basic rule of thumb to follow when choosing a blower is that it should deliver a constant airflow of 0.4 CFM per foot of aeration tubing. This holds true regardless of the length of tubing used. However, in order to deliver the required 0.4 CFM, higher horsepower ratings will be required as both the footage of tubing and the water depth increase. Since each manufacturer of blowers has different specifications for their units, it is recommended that you refer to the flow and head loss charts that relate to the unit you choose.
What type of blower should I use to power Swan Aero-Tube™?
For larger aquaculture aeration systems, it is important that you use a “clean” air blower, such as a regenerative blower or a positive displacement blower. Never use an air compressor or any other type of unit that may emit oil or other residue into the system. This will not only cause water pollution, but will lessen the efficiency of the tubing as well.
In addition, flow valves should be used to balance the airflow to each segment of the system, and blowers should always have a clean air filter in place during operation. Proper maintenance and care of the blower will help to extend the life of the entire aeration system and, in turn, will help to maintain higher production levels.
