Nicro Vents Or Similar

[EJO]

I need to change an old Nicro 4" solarvent and I'm of course looking for the best price.
Can anybody tell me what is the difference between a Nicro Model N20604S and N20704S or even N20504S. I understand the S for SS, the N for Nicro and the 04 for 4" diam, but they all say 1000 cfh so what is the difference in 5, 6 or 7 as the price is different and nobody sells all models so I don't really no the street price.

FWIW Defender.com has a sale going on right now.

I don't know the differences between them off hand, a quick call to Defender and they should be able to tell you. I Have had mine for a few years now and think they are great, you will need to replace the rechargeable POS battery they send with them though, but thats an easy fix.

there are a couple of different generation of Nicro power vents. The older ones (close to 300.00) seem to have a better durability reputation although Nicro seemes to be good about replacing the newer ones under warranty. (while in warranty)

There are some threads about them on here...

Here is a thread on mounting a computer "muffin fan". I got all the parts back in Nov. but haven't done the install yet. I may try it this week

My current motor works fine, the solar panel won't recharge my new battery plus I want one exhast and one supply therefore I need to buy a new one.
What is the difference in these model numbers as in my original question.
I know how to fix, or build a new one. I have read the various threads on the internet, but I still don't know what the difference in a N20504 or 604 or 704 is.

you may have to click translate.

The 20704 can be switched over to your boat's 12v electrical system for more rpm's.
