They can be wired to any electrical source and are typically wired so that the electric gates open when the machine or process is in need of dust/fume collection

Vibration Dampener Flanged Bell Mouth These gates come with aFans and other machinery can generate vibration that is conveyed through the metal ducting pipe. Vibration can increase damage to adjacent machinery, and create unwanted ambient debris (dust) and excess noise. A vibration absorbent membrane is used between two ductwork connection ends. The dampener effectively absorbs vibration and prevents it from passing through to the other parts of the system. Reduce the transference of vibration. Gauges to match
