Top 5 Questions: to ask every dealer before purchasing their pond aeration windmill.
Does your windmill tower have 3 or 4 legs?
Three-legged windmill towers simply lack the strength and stability that four-legged towers offer. They are often seen as unstable and can easily fall over., in fact. Some companies have discontinued manufacturing them for this very reason. While it’s true that a three-legged tower may have a lower initial cost, that attractive price tag can quickly lose its appeal if the windmill collapses, leading to the need to purchase replacement parts.
Do your windmills come with solid rebar ground mounting rods or the low-grade thin hollow tube for mounting?
There are fundamentally two categories of ground mounting rods designed to anchor windmill pond aerators to the ground. The first type consists of low-cost, thin metal hollow tubes, while the second type is the industry standard, which is made of solid rebar. Despite the application of protective coatings, thin hollow tubes are susceptible to rusting through over time, which can compromise the stability of the windmill. In contrast, solid rebar mounting rods do not present
this issue, ensuring a more secure installation.
What gauge metal is your tower made of?
When buying a pond aeration windmill, it’s important to pay attention to the metal gauge of the tower. A heavier gauge means a sturdier tower, and while many brands opt for lighter 18-gauge metal, we at Joe Mescan Windmill LLC take pride in using a more robust 14-gauge galvanized metal for our towers. This choice ensures greater strength and durability for your windmill.
Is your windmill a diaphragm or a bellow compressor?
There are fundamentally two categories of windmill compressors: the diaphragm compressor, which generates high pressure at low volume, and the bellow compressor, which yields high volume at low pressure. Some manufacturers claim that their windmills can achieve both high pressure and high volume; however, such a combination is not feasible according to the principles of physics. In the context of pond aeration, a bellow compressor is significantly more
effective to introduce a greater volume of air into the pond rather than relying on higher pressure diaphragm systems that only deliver low volumes of air.
What is a freeze control unit & do I need one?
A freeze control unit is an inline tank that dispenses a deicing liquid into the air line, thereby preventing the formation of ice from natural condensation build up that could obstruct the windmill’s ability to pump air into your pond.
The high output generated by the bellow compressor eliminates the necessity for a freeze control unit. In contrast, many diaphragm models produce low output and do require such a unit. If a seller of diaphragm windmills insists that a freeze control unit is essential, they may either be misrepresenting the output of their windmills or attempting to sell you an unnecessary product.
