Description
The TD Inline Mixed Flow Fan in 400mm is a duct-mounted fan that fits within a run of 400mm ducting to provide extract or supply airflow. This model is the three-phase version; a single-phase version is also available at this size.
Mixed-flow in-line fans combine the compact, straight-through installation of an axial fan with improved pressure development, which makes them well suited to ducted systems with longer runs, bends and grilles to push air through. Fitted in a ceiling void, riser or plant space, a TD fan powers bathroom and utility extract systems, office ventilation and general commercial supply and extract duties.
Key features
- 400mm spigots for direct connection into 400mm duct runs
- Mixed-flow design suited to ducted systems with resistance from runs and bends
- Installs in ceiling voids and risers — extract or supply
- Model reference TD-6000/400-3PH
- Range available from 100mm to 400mm
