The prototyping service from Universal Air Filter, Sauget, Ill., for its Windowpane product line has added production capabilities to the Flex-Frame filter assembly model. Mechanical and product design engineers as well as industrial designers can use the prototyping service for free in conjunction with the 3D CAD downloads available at

"Previously, the roll-formed channel frames were the only products available for download and quick-turn prototyping," says Mike Miano, engineering and sales manager. "Now, design engineers wanting Flex-Frame air filters for applications requiring a flexible or non-conductive frame can request a free prototype and have it in their hands within a few days."

Flex-Frame models allow design engineers to select the number of openings and intermediates needed in their filter design, which can be downloaded into any 3D modeling software package such as SolidWorks or ProEngineer. Once the designers download the model into their product assembly to check the fit and possible interference points, they can submit a prototype request online, by e-mail or by phone. Universal Air Filter will create a custom prototype and ship it to the designer within a few days at no charge.For more information go to
