Time Overrun Extractor Fans
16 products
These fans are usually connected to your bathroom lights or via an on off switch. Time over run means the extractor fan will remain on for a pre-set time - usually 2-30minutes after you have sitched off. This helps to control the level of humidity in your room.
The run-on timer control option requires live, neutral and switched live electrical connections to your fan (earth is not needed). The switched live connection is used to operate the run-on timer. The fan will continue to run after the switched live has been interrupted by your switch or pull cord. The run-on time can be adjusted inside the fan from between 2 and 30 minutes.
- Live, neutral & switched live connections.
- Connect to your lighting or household circuit to operate by your light switch, pull cord or separate switch.
- Built-in run-on timer.
- Connect to an electrical circuit to allow the cooling of equipment after switch off.
Tip: Building regulations state that if your room is enclosed with no opening windows, then a fan with a run-on timer must be used.
