Versa-Vent II 12v Background Fan for 50mm Vent Pipe

£45.00 inc. VAT

Continuous, low speed, virtually silent ventilation 12V fan that connects to 50mm vent pipe for odour and moisture control inside your compost toilet.


The addition of a ventilation fan for your compost toilet should completely eliminate all odours and in addition, will help to control the moisture levels inside the toilet. The fan is designed to be run continuously (although many people do switch it off at night for example). We still recommend the use of some cover material in addition to the fan as the cover will act as a visual barrier as well as improving the final compost mix.

If you order a Versa-Vent II at the same time as a Kildwick compost toilet, we’ll contact you to determine the best fitting position for your installation.

The Versa-Vent II will require a 12V connection, but only draws 50 milliamps.

The Versa-Vent II connects to standard 50mm plastic pipe such as ‘PolyPipe’ which is available, along with fittings such as straight connectors and elbow joints at low cost in many DIY stores and builders merchants. Simply run the vent pipe from the toilet to the outside, ensuring rain cannot enter the pipe. Any odours will dissipate quickly within a metre or so of the exit.

A 240V AC to 12V DC adaptor is also available to enable the fan to run from the mains.
