Air-Only Ventilators - A question. Perhaps someone in Europe knows.

I don't post too often here anymore. But back between 2007 and 2016 or so, this site was responsible in large part for a restoration that I did on a 1973 Silverton Sedan. I did the grunt work but I could write for hours about all the help and encouragement that so many provided. I'll post a photo of my boat and below ask a question.

When I built the boat I decided not to add a hatch to the foredeck. After running the boat for a dozen years I'm still OK without a hatch. But I'm doing some long distance traveling now and would like to add some ventilation to the cabin. So I've been looking at vents and dorade boxes.

I came across a company in Europe. In Ukraine. Air-Only Ventilators seems to have an interesting approach. I'm wondering if anyone has any opinions on their products.

Well, it looks pretty good. But I have never used one.

 

I've never seen one used either, but they look a lot like an "improved" Nicro Fico/Marinco low profile vent. It is important to note that both of those vents were powered. Given the flow complexity and float restrictions of the Air-Only vents I would expect them to need forced intake/exhaust also.

 

Thanks for the replies guys. Jehardiman, Air-Only does offer a powered ventilation fan as an option. Below is a link to their product line. The fan option will flow about 50 cubic meters per hour and has a couple of speeds according to air only. It's using a small computer fan, only draws about 0.12 amps @ 12 volts. I'm just trying to find out if anyone has actually used one of these and how they liked it. I'm fishin for some opinions.

I've never seen those exact ventilators,but Ukraine is quite a long way away.The almost universal equivalent from Vetus is very common. https://vetusonline.com/english/ufo2.html

 

Have used the Air-Only type with good results; has quite low internal losses, so works fine without fan, yet efficiently blocking water entrance. The Vetus model not good enough in exposed positions, like MIA's fore-deck.

 

Thanks for the feedback baeckmo. That was just what I was looking for. I appreciate you taking the time!

 

I received the air-only ventilator from Ukraine on April 1st. I ordered a couple of the low profile vents with the optional fans. Items came well packaged and were undamaged in shipping. Ordering process was straight forward. A little different than ordering from an internet retailer in the United States but I had no issues. There was a one week delay in getting confirmation on the order. After that the communications was fine. I ordered the item on March 1st, so it took exactly a month for them to get it here.

Maybe this information will be useful for someone considering using an air-only product.

Thanks to everyone who weighed in on this.
