43 DS - Cabin Fans

[alenka]

Hi Folks,

Can anyone pass on experiences of installing cabin fans in a 2004 SO43 DS.

I have switches for them on the electrical distribution panel and I gather wires will already be incorparated into the loom. I really just  need a clue as to where these terminate in each cabin so I don't have to pull out every panel.

All comments appreciated

Have you checked your 43DS owners manual, the electric schematics??

Hello alenka,

Many years ago I installed fans into a SO36i. I was impressed that the wiring loom was already in place. A fuse was needed in the distribution board to liven up the cabling.

My experience is detailed in Hints and Tips here, www.jeanneau-owners.com/hintsandtips/cabinfans.html

The fans I put in did work quite well but were a bit noisy and if I were to do it now I would spend more money on the fans for better quality.

Good luck with the installation.

Regards,

Trevor

Hey Trevor ,

problem with this kind of ventilator is that the old (humid) air still stays inside the cabin.
This year I finally aranged a fresh air vent inside the stern cabin .
Nt sure if that is helpful for the TS , but I'll share it anyway. Maybe some stuff for Malcolm's H&T


Air inlet at the stern.



As a ventilator I've used a engine compartment blower , lots of power and high flowrate.
Of course I made sure the suction hose curves slightly higher than the inlet.
Using this type of blower also gives me a spare unit to be used just in case the engine compartment blower stops pulling its weight, it's the same model you see.



The blower discharge picks in on the back cabin separation wall.



As you can see there's a possibility to change the direction of the flow.



Here's a stepdown convertor so the blowers rpm - and subsequently the airflow and amps- can be controlled.
Don't use a pulse width modulator for rpm control , as the blower will scream your ears out , not the way to go when you're in the berth sleeping, now is it.



I took this blue variable resistor out and replaced it by a normal potentiometer.



Built it into the cabin light , that way I also had acces to the neccesairy supply.
After all , when you need the fan ,you're in your berth and no doubt the main lightswitch (controlepanel) will be on.
Oh yes , naturally the light doesn't have to be on to allow the ventilator to work

Hope it helps
regards

Nice work Sailbleu,

I have the opportunity to use the Webasto heater in "ventilation mode" if I want to have some circulation in the current boat but quite right about circulating the internal air.

In fact we do not have fans in the current boat. We have a cheap 240 volt fan that we sometimes just put where we want and use with the help of the inverter.

That looks like a good one for H&T. I like the extension of the regulator pot up to the light fitting. It sounds like you tried the PWM system prior to going to a series regulator. Very good. You certainly do stay busy!!

Trevor
