The product Build Time you see represented on this site is only a typical number of days the manufacturer states it needs to build the product(s) when ordered. Build times are based on business days (excludes weekends & holidays).
The build time does not include the time it will take to ship the order to you (the customer). If an order has multiple items and comes from multiple warehouses, you may receive part of your order on one day, and then receive the remaining part(s) of your order at a later date.
*Please be aware that seasonal demand of certain equipment may cause build times to run longer than what is typical.
For our new centrifugal spun aluminum power roof ventilators we've set fan efficiency as our number one goal. We knew the wheel, the heart of the unit, was the place to start so we took meticulous steps to design and engineer the most efficient and cost effective wheel we could. Our new wheel features curved blades, solid rivets and improved cooling vanes which together ensure the best fan performances possible.
Since efficiency was a key factor in the design we looked to increase our manufacturing
efficiency to save on costs and ultimately save you, the customer, money. Commonizing parts, improving manufacturing processes and creating a more robust product not only created a lower priced unit, but also lowered the operating cost over the lifetime of the product. Additionally, through improvements to important structural components of the fans we increased the overall strength of our centrifugal fans compared to our older models.
