The Branson Silver Booster 900 Series (Part No. 101‑149‑053) is an aluminum O‑ring booster engineered for 20 kHz ultrasonic welding systems, particularly the 2000/900 series welders. It offers a 1:2.0 amplitude gain, effectively doubling the ultrasonic vibration from the converter. This booster features a silver color code, signaling its high-amplitude gain in Branson’s color-coded system. It uses a 1/2‑20 threaded interface and is widely compatible with integrated welders like the 2000 IW and IW+ models.
