Anderson plug is a 2 pin but probably bit heavy just for a fan?

You must already have an earth connection to the Van so you only really need a single pole connector.

The fan is a low current drawing device so just run a single wire from the ignition/accessory circuit to the fan and an earth connection from the fan to am earth (metal) object on the van.

Anderson have the Powerpole connector available in a range of colours, or you could install two if you want a separate earth (return) wire.

Do you have a battery in the van? Is it charged from the vehicle? If so just connect the fan to the van 12 volt circuit.

That is the appropriate question Rod. Usually you will find that even the simplest poptops have a battery to charge and you won't get sufficient power through a 7 pin trailer cable to charge very much at all.

Totally agree John. I use an Anderson plug to charge my van battery and run the fridge when under way. Garny should do the same. It's amazing how many people are told by those that should know better (installers etc) that a trailer plug pin is sufficient to charge batteries and run fridges.

Thanks for the info guys at the moment the van has a small battery to run the water pump only i will be fitting a larger one to run lights etc and also an anderson plug
I will run the fan of the vehicle accessories so as to control on of when travelling will run through anders plug
The fan will draw from a vent through an air cleaner filter high on the side of our Windsor Rapid
cheers to all

most dust enters due to a negative (lower) pressure than the outside of the van.....meaning it is pushed in by the higher pressure.

where are you going to fit the fan so that it will be in CLEAN air and can keep the van at a higher pressure than ambient?

There are a number of threads on this subject if you do a search. Pros and cons of fans and scupper vents have been discussed at length. Of course opinions vary as to the effectiveness. If it is a van and the vent is in the roof, it is thought by some that the air is cleaner.
