The fans cost about $90 each and the PWM controllers about $1.50 each.

It looks like your PWM controllers are after-market and not built into the fans? Be aware that some motors may overheat if run at low rpm and I suggest you put a hand on the motor body to test its temperature after running the fan at low speed for 20 minutes or so.


 Yes, thanks for that. I am aware of that so as part of my install test I kept an eye on temp of the fans & controllers.  That's the controllers in small electrical boxes on the wall under the fans.

Someone built me a DC transformer for model trains so the train could run from full speed down to stepping the motor to the last mm. The control over the train was brilliant, but the sound from the motor was horrible due to the chopped supply, so I stopped using it.

Friend with a 20Ft Tandem and roof top Air Con has purchased the items below for when its hot at night in a CP or else where and he cannot run the generator to drive the air con and he wants to get to sleep.

He has tried it out and very happy with the result, and the small ice blocks will hopefully fit in the unit.

Will probably get a similar set just in case, maybe OK for our 22Ft caravan but dont know re our Mercedes Benz 6.5mHigh Roof Sprinter Campervan, dont want the roof to rust out from the inside like some Nissan and Coaster motorhomes, but if only used in dry hot air locations for minimal time should be OK.

I've noticed ads for Delonghi Portable A/C's lately that may fit the bill www.binglee.com.au/delonghi-pac-cn93eco-pinguino-air-to-air-portable-air-conditioner

We purchased something similar a few years ago, put ice water in, and the fan blows cool air out, through a filter

The wife used it once, and it now sits in storage, under the bed

I know that we are all different, but I would never buy another one

Inclined to agree, JayDee!

I have a Trayon slide-on without a/c. I have a 12v fan and use a spray bottle to keep cool, BUT... only in the annexe or shade! I also bought a little personal 12v evap cooler, which is OK, I guess. Again, only in the annexe or shade. Cooling down a van requires a lot of energy and is OK if you have 240v supply and a compressor a/c. Evaporatives are fraught, so just keep a fan and spray bottle for personal comfort and forget trying to cool down a van unless you have a proper a/c and access to power.

Or go swimming.

Thanks folks,.

Just as I thought.

We will not waste our cash on this unit, instead we will buy another 12 volt sirocco fan.

 "They are great (and heaps cheaper than refrigerated aircon), but not available for a caravan"

Well... It is only up to yourself if you would employ a plain domestic evaporative air cooler in your caravan, just a selection of the size to fit in your type of RV, and no problem, isn't it? I use it in my modest, DIY type Motor Home, transformed into an MH, from an old 1981 truck, Toyota Dyna, and I'm happy with it. There is nothing to stop you, too. If you chose to do so, install a small inverter - even 600W will do fine for starters - and enjoy it. I use also a plain 240VAC fridge from Aldi. It just a plain,  small, domestic, 129 litres/240VAC fridge. Al this, with lights and laptop, and other things run now from 1000W inverter 12VDC to 240VAC. Before I used 600W, but after 3 seasons, I decided to upgrade, after the Chinese thing quit to function. No drama, served me well for some years, and I got it cheap too, any "named" type would cost me at least 5 or 6 times as much. All cheap and affordable, and well functioning. This way, I use my money as I want and need myself, not to feed the "names", just because they have names. I have a name too, but since nobody would pay ME for it, I choose too, not paying THEM, for their names. Just simple like that. I got a lot of better uses for my money, friends.
