Stainless Steel Air Vent

Produce compliant, on the other hand, no fixing screws for the stainless steel cover On the other hand it would have been good if the flange was provided

Price performance as always great.

This Taiwan replica of the ECS fan mounted on many yachts is extremely attractively priced, but you have to accept a few disadvantages
The hole circle of the 4 outer screws in the stainless steel sheet deviates from the original, so you have to drill 4 additional holes in the deck. The supplied screws are consistently too thin for the existing holes and must be procured to match. The dimensions of the ventilation hole and the hole circle of the 6 retaining screws of the plastic parts are exactly the same as the original.
On the other hand, if you only want to replace the plastic parts and keep the cover plate, this is not possible because the size of the light entry opening is not identical.
Of course, you don't have these problems with a complete new installation, but it is noticeable that the designer of this fan copied the original without understanding how to assemble the clear water deflector and the deck flange do not really fit together well. For the form-fitting assembly, it was necessary to place 3 suitable polyamide washers between the deck flange and the water deflector to prevent the forces from causing mechanical damage when screwing. Unfortunately, we will only know when the time is up whether the UV stability of the plastics used is sufficient for this fan to also survive the 38 years that the ECS original survived.

The stainless steel sheet is quite thin compared to Vetus. The assembly sketch is more than poor. You think you can't do much wrong. But if you hold the insect screen in your hand, you get brooding. I didn't get it right. Doesn't look good from above.

A UFO fan from the "ecs" brand was installed on our ship. The plexiglass cover was yellowish and brittle. Since I couldn't find any more fans from ecs, I tried this product and the fan from Talamex as a replacement. This fan is from "AAA" and made a slightly better impression than the product from Talamex. Basically, the products from "AAA" and "Talamex" were identical.

However, the stainless steel cover is extremely thin at 0.49 mm compared to the 1.2 mm of the ecs fan. The holes also don't fit 100%. I therefore combined the white plastic part and the plexiglass cover from the new "AAA" fan with the old stainless steel cover of the "ecs" fan.
The cutout in the ecs cover was a few mm larger.
Conclusion: I was able to repair my old ecs fans with it. For a new installation, I would choose a different, higher quality product.
