Lomanco Whirlybird® Turbine Vent - Maximum 301 Comparison

lamento vince product comparison this is a comparison of the maximum 301 static roof vent and the Lemang co whirlybird wind turbine if you're trying to decide whether to install a Lemang Co whirlybird or a simple static type roof bin here are a few facts you should know first the Lemang Co whirlybird is a dynamic wind powered ventilator that actually works as a wind pump to exhaust the heat and moisture out of your attic space the cubic feet per minute or CFM flow will accelerate as the outside wind speed increases this is confirmed by independent testing at the Texas engineering Experiment Station at College Station Texas but see for yourself here it is proven very simply static exhaust ventilator watch what happens when I simulate the wind speed improved exhaust capacity greatly improve intake capacity better performing VIN so there is no doubt that the spinning action of a low Manko whirlybird greatly enhances the performance of that vent no matter what the other guy claims this vent is a static ventilator which means it just sits there and while static vents are not bad they will never outperform the airflow that the Lemang co whirlybird can achieve levan co is tested both vents under the exact same controlled conditions and as a matter of fact and record the Lemang co whirlybird exhaust more air than the maximum 301 at all wind speeds the 12 inch where the bird has 37% more airflow and the 14-inch has 88 percent more airflow what does this mean it means you need fewer wind turbines to ventilate the same attic area something else to consider the maximum vent in its own published report states that it lets air flow backwards into the building this means that your exhaust vent is now an intake vent and short circuits your whole ventilation system of course the report also states this was tested over a piggery housing with some 96 grower hogs if an exhaust vent does not exhaust 100% of the time you will have problems a properly installed whirlybird will never reverse its airflow or let air and weather come into the attic space Lemang co has been in the ventilation business for over 68 years and over 35 years in the canadian market we do not do our testing at a pig farm Lemang COEs testing research and engineering facility is truthful trustworthy and world-class the maximum weighs in at over 26 pounds they even show at least two people needed on their instructions to install and state that a generous amount of roofing cement is required to prevent leaking engineered for strength and still weigh in under four pounds the Lamont Co whirlybird is quick safe and easy for one person to install with common hand tools the maximum is made from galvanized sheet metal with exposed edges that will ultimately rust and stain your roof it also has an inferior warranty when compared to the Lamont Co whirlybird turbines all aluminum rust-free construction and forever guarantee that's right the Lomonaco whirlybird is guaranteed forever as long as you own your home and is fully transferable from home owner to home owner the whirlybird is available in standard colors of mill white black brown and weathered bronze you get thirds in all their standard colors of brown black gray and that's it Lemang co turbines are packaged in a unique box that protects and ensures Lemang co where the birds reach the jobsite undamaged overall the whirlybird proves to be a superior attic ventilator while providing equal or better weather infiltration protection than the maximum 301 static roof vent whether you're a home builder or homeowner the best return on investment for protecting the longevity of your home is the proper installation of a balanced ventilation system with the proven performance and quality of Lemang Co Vince if you want more information on the Lemang kohlberg or Lemang CO vents visit Lemang cocom you can also find us on facebook and subscribe to our youtube channel
