Round vent draught covers

When I was at Marquis Northants back in November on one of their Marquis Majestic motorhomes it had one these covers fitted over the round vent.

Our Broadway has one of the round vents on the outside wall where the microwave is sited, presumably to let out heat but when the wind blows it's pretty drafty around the microwave 

I asked the manager at Marquis Northants if they could supply one of these covers and he didn't have a clue, showed him the cover on the Motorhome in the showroom and he said he'd find out, needless to say I never heard no more (surprise surprise) I understand swift make the majestic for Marquis 

Has anyone seen these anywhere as I've looked online and can't find anything like it anywhere? Another concern is the current round vent appears to be completely open as is the one on the opposite side of van into the back of the wardrobe and neither even have a fine mesh inside like some I've seen so what's to stop spiders, insects or wasps getting in though these into the van? 

Will be very interested if someone comes back with details as we have the same problem. Like having air conditioning on full cold all round the microwave and the vent for the microwave 'inside' the van. I have had the inside vent blocked virtually since we had the van and was going to remove and fit a blank behind the outside vents and then refit them but didn't want to disturb the sealant. We rarely use the m/w as not often on EHU and I am sure the internal vent which is quite big would do the job anyway.
Good point re insect ingress, will go and have a looksie to see if ours has mesh.

I can get the vents with mesh from my local camping shop off the shelf or Amazon which would stop the insect situation (has anyone personally had insects in via these vents out of interest?) 

The vent covers pictured would certainly cut down on drafts though 

CC,
I think you will find that the round vent on the 'off-side' of the van is the balanced flue of the Boiler/Heater.
Best to leave that one alone!
We did not get the microwave (or indeed the TV) with our 18month old van, so we do get quite a draught coming through the vent bend the microwave shelf.
I shall look into ways of reducing the airflow through it although I am always wary of blocking off all avenues of ventilation.
Would be interested to hear if you source some suitable product as per your pic.

Hi Backtrax 

Finally tracked down this part... 

Turns out it's an Eldiss part and is manufactured by ESP plastics 

Marquis got me one but when I came to fix it I noticed it had been filed at an angle on the back so the recess was lower on one side than the other, it's fitted ok'ish but I'm looking into obtaining another from another source either an Eldiss dealer or direct from ESP plastics although it looks like they might not sell direct to anyone other than the trade.

I cant post it this week but I have a pic of one installed on a friends AS. Also another friend is looking to make a mould to make some triangular shaped covers. Modelman could produce some, pity he's retired.

This does throw up an interesting dilemma.

Whilst the vent cover facing backwards will create a vacuum pulling air out of the van, when travelling or when the wind is head-on, it will actually force-feed the draught when the wind is up your backside...............so to speak.

Opening facing downwards.............???


As a matter of interest, my retro-fit m/w has no ventilation whatsoever, there again we only use it occasionally. I'm pretty sure this would be the case for all retro-fits.
I wonder if any members have had any damp/mould issues in this area?

What about one of these instead...

Hi Derek... I don't follow mate, the vent is fitted with the opening facing downwards? Maybe my photos haven't published to the forum in the correct orientation but view ok on my iPad.

Having contacted a local Eldiss parts dealer & ESP plastics direct I've had a reply from neither which I kinda expected as that seems the norm in the Motorhome industry, it's extremely rare to get any kind of reply 

With regard the vent fitted I'm more than happy with the design, as its purpose made to fit the round vents and I think they look neat and more attractive than the open round vents, just wish they were more easily obtainable as it's took me six months to source just the one!  Not been away in the van since fitting it, but it's certainly noticably less drafty sitting on the drive so seems to work as hoped
