The VMC Group Wide-Flange Bases for Structural Fans are structural steel channel bases with motorslide rails and open spring isolators with 1″ – 5″ deflection. The Wide-Flange Bases for Structural Fans are available in various shapes and sizes.
VMC Wide-Flange Bases for Structural Fans are designed for fan wheel diameters from 12″ – 73″ and support motors up to 100hp.They are available for single width and double width fans, classes I,II & III. Bases can be fabricated without motor sliderails for use in other fan arrangements without an integral base. VMC Group Wide-Flange Bases for Structural Fans help maintain proper drive alignment and resist starting torque. The isolator housings are identical in height within each series and come with easily accessible bolt holes for simplified installation. An elastomeric acoustical cup eliminates high frequency vibration, while color-coded springs permit ease of identification of load capacity. Spring housings have internal adjustments for use in most seismic and wind applications. Their rugged steel housing is designed to handle high wind and high seismic forces up to 2.0g.
When an equipment submittal drawing is provided to the VMC Engineering Services division, a properly designed base or rail drawing, indicating seismic isolator model numbers is produced for customer approval. Once approved, drawings are provided to our manufacturing department for fabrication and shipment.
