The range

The Xpelair LoSound range of attenuated inline fans consists of six models for use in ducted applications where high performance and low sound levels are required. Suitable for commercial and industrial applications such as schools, shops, offices, pubs and restaurants, the compact design allows easy installation above suspended ceilings or floor voids using the mounting points provided. The high performance, low noise level motor combined with a cabinet lined on four sides with 40mm sound absorbent material makes LoSound range particularly suitable where low sound operating levels are necessary.

All models can be installed with the covers upwards or inverted.

The Xpelair LoSound range is suitable for ambient temperatures up to 40ºC.
