Eco-Loo 12v ‘Quiet’ Fan Kit – 60mm Fan, 68mm Pipe connector


Provides constant low-speed, low-noise ventilation to ensure an odour-free experience with either the Eco-Loo Compost Toilets or your own design. Quiet and low power consumption at 12V DC. Standard 68mm ‘downpipe’ fittings for simplicity.

Also available as a 24V DC fan – please enquire.


The Eco-Loo ‘Quiet’ Fan Kit can be fitted to your own design of compost toilet or the Eco-Loo Divert or Capture and provides a high quality, low noise 12 volt DC fan built into a custom housing for ease of installation.

Also available in a 24V DC version – please enquire…

The housing fits from the inside of the toilet and is secured with screws (or glue) – a cylindrical protrusion from the rear will then accept standard 68mm round ‘drain pipe’ fittings to enable you to run the vent pipe outside.

In order to fit the fan, you will need to cut a 64 or 65mm hole in the back of your toilet base (most Eco-Loo bases come with the hole pre-cut).

Typical Eco-Loo Fan installation

The fan is classed as a ‘silent’ fan – not strictly speaking 100% true, but it’s the quietest fan we’ve found (under 20 dBA) that still offers good performance and extremely low power consumption, making it ideal for off-grid / solar / wind powered installations. The fan is a high quality unit (brushless axel fan with ball bearing) – the low noise is achieved through excellent blade design and high quality bearings on the motor – although there are much cheaper fans on the market, they are often twice as loud as this one which can become a considerable annoyance.

Please note this fan requires around 12 volts DC and consumes around 0.8A (under 1 watt). If you wish to connect this to the mains, you’ll need a 240 volt AC to 12 volt DC adaptor that can maintain around 80 mA / 1 watt – we also sell these, so check our website…

We also offer solar panels and complete solar kits which can power this fan (and some LED lights if needed) where no other power source is available – check out our solar products.

How does it work?

The fan can be run continuously and will draw air over the ‘solids’ bucket in your composting toilet and then out through standard 68mm drainpipe where any odours can be passed outside where they’ll quickly dissipate. The act of drawing air over the solids container creates a slight low pressure in the solids bucket which will also help to draw moisture out, further reducing the odour potential and accelerating oxidisation of the contents. With urine-separating toilets, the key is keeping the moisture levels under control – a fan will assist with this, as well as assisting with odour control.

We’d recommend as short a run of vent pipe as possible with as few bends. If possible, keep the vent pipe length to a maximum of 2 metres. Make sure your toilet has adequate air flow (ie your must allow fresh air into the toilet box) otherwise the fan will labour and efficiency will be reduced.

The use of the fan means that you don’t have to to use as much sawdust, wood shavings or other cover material after each ‘solid’ deposit, although we still recommend having some cover material available for people to use if they wish. Adding some cover material will greatly enhance the composting process by balancing out the carbon and nitrogen levels.
