The GAM Products TwinSpin II is a variable-speed pattern rotator designed for use in the gate of an ellipsoidal for projected effects. The rotator uses drive belts to rotate two B-size patterns, glass or metal, in opposite directions. The motor can be controlled by dimmers, without the need for a special controller or cables. A built-in variable-speed control that eliminates the need for a dimmer is also available. The patterns are held in place by a spring steel retaining ring, so changing patterns is fast and simple. Teflon glides between the mounting rings and stainless steel housing ensure quiet and smooth operation. The motor is mounted on vibration pads to minimize noise. The low-profile motor is offset away from the hot air flow and drives two high-temp belts that rotate the patterns. The transformer is UL-listed. GAM PRODUCTS Hollywood, CA
