Description
The Turbo In-line Mixed Flow Fan in 4 inch is a duct-mounted fan that fits within a run of 4 inch ducting to provide extract or supply airflow. This model is supplied without a run-on timer — a timer version is also available.
Mixed-flow in-line fans give the straight-through convenience of an axial fan with better pressure performance, so they cope well with ducted systems that include bends, longer runs and grilles. Mounted out of sight in a ceiling void or loft space, a Turbo in-line fan is a popular choice for bathroom, shower room, WC and utility extract, as well as general small-duct ventilation duties.
Key features
- 4 inch spigots for direct connection into 4 inch duct runs
- Mixed-flow design handles duct runs with bends and resistance
- Standard (no timer) version — timer model available separately
- Model reference TUBO-U-100
- Range available from 4 inch to 12½ inch
