Time Overrun Extractor Fans

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.
