These High Output acoustically insulated wooden box fans are made of MDF (medium density fibreboard), which is an excellent material to construct the box with as the more fibrous a material is, the greater it's ability to absorb sound. They are solid in construction and the commercial grade high quality Torin fans are available in varying high outputs.
