The candle holder has a support foot (1) and a conical cap (3) is mounted above it. The cap is fixed to a tube (4), extending from the top of the holder. An extractor (5), fixed inside the holder, is joined to a concentric tube (7) inside the tube above the holder. The free space inside the holder is filled with rock wool (6). Filtering foam (8) fills the space above the top of the inner tube. The exit of the aspirator is joined by a tube (9), inside the foot, to a noise absorber (90) mounted on filtering foam (91).
