The Elta 068‑0150-JF1 is a compact silencer measuring 150mm in diameter and 300mm in length, part of a small metric range of noise attenuators. It is designed for use with small fans to reduce operational noise and eliminate cross talk between duct sections. Featuring a spigot connection, this silencer is compatible with flexible or spiral ducting, making it an effective choice for ventilation systems requiring noise control in limited spaces.
