VMC Group Fan-Spring and Motor Bases are structural steel angle iron or channel rectangular bases with motorslide rails and seismic spring isolators with 1" or 2" deflection. Custom deflections are also available upon request.
VMC Fan-Spring and Motor Bases are designed for use with arrangement 1, 2 & 3 single width or double width fans with belt-driven motors. Bases can be fabricated without motor sliderails for use in other fan arrangements that do not have an integral base. VMC Group fan spring and motor bases 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 VMC Group's 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.
