Folks, I need to upgrade my vent and fan, both of which have deterioated. i am thinking stick with square style. On a previous unit I had a nice maxair with remote and I think two way fan. I gue ss with the remote it was a powered vent, I was wondering if you could get a power vent with option to manually open if power failed. The Maxxfan Deluxe looks good in a catalogue. I have two vents on a 24' unit. Is the Vortex and different brand or more powerful and compatible with the Maxxair vents? I should dprobably forget vortex and be content with the Mzxxfan deluxe. I am confused as I see later in the catalog Maxair original vent cover which I got years ago and the new maxxair 11. It looks taller than the maxfan deluxe cover. Opinions please. Doug
For now,Boomer, I think I will do the same as I don't want to have to remove lid base and caulking on the roof. Actually I just need new lids but the Heng will be a simple upgrade on the fan, thanks. Doug
