dad :

Welcome to the PB forum. There is a lot of info here on windmill aeration including types.

I think that those Forum members who are distributors will be very reluctant to answer your question as asked on the open Forum. The reason is that Forum rules prevent sales activity here. People are welcome to take part and help others but can not engage in sales activity for a host of reasons.

Guys if you want to answer this question (make a sales presentation) please help dad out but do so in a PM or email .
