Centrifugal Spun Aluminum Products SDB • SDBD • STXB • STXD Downblast & Upblast Centrifugal Roof and Wall Exhausters Designed with Efficiency in Mind CSAP_0716 July 2016
Centrifugal Spun Aluminum Line Overview When we started the project to improve our upblast and downblast spun aluminum power roof ventilators we 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.
Centrifugal Spun Aluminum Line Overview We designed these fans so you can use smaller models and motors to meet the performance needed. With our new centrifugal spun aluminum line we are able to deliver wider performance ranges and unit sizes. The charts below show sample comparisons of the SDB and STXB vs. common competitors and the old DB and TXBs. These charts show at the most common static pressure points of these models (.25 to 1”) the new SDB and STXB have more CFM/BHP.
