Many of us older CC's came without a AC Diffuser built in.
Our coach has the Dometic Penguin II's 15K units installed. Yes they are ducted, but they also have the plastic grill return and cold air direct dump from the bottom of the AC unit. These are loud. Closing the direct air dump does reduce the noise some. The filter is, well, I suppose they do filter some...
Our coach was before the increase of internal headroom height, so space for tall people is a factor.
All of that leads up to my question to fellow CC owners with the similar set up for AC that we have in our era coach. Has anyone tried the WackO Products DA100 silencer and filter? And if so, how much noise reduction do you feel your seeing as far as a percentage.
I've read a few reviews, where people used their phone to do a before and after decibel reading. One gent in a non CC said his went from 77 down to 72. While not a dramatic drop at about 6.5% reduction, but it is some drop
I do feel the filtration would be superior with the WackO setup.
I'm 6' 2" (Used to be 6' 3.5" -but 40 plus years of the DW grinding me down
!), so head room, especially with a ball cap on, is a factor for the front AC unit...
Another reason for posting this here in the CC Owner's area, is that I read comments that some felt they missed the ability to have the direct Cold Air Dump from the unit. The loudest exhaust of cool air into the coach for sure. But also the one with the greatest air flow. A few felt that their specific coach design of the ducting systems itself, was not able to completely handle the increased volume of air when the Cold Air Dump grill was closed off. (We personally quite often close our front grill off, to reduce the noise level while watching TV. Leaving the rear zone (We have only 2 AC's, others of cours will have 3 and a few CC Prevost based units may even have 4(?).) Cold Air Dump grill open at these times, with a small fan blowing towards the front of the coach, in extreme over say 105 degree temps. And if we're needing to catch up with the heat gain, we will leave the front zone open too as needed.)
So was wondering if any other 40-42' coach CC owner's of my era have any first hand experiences on this product?
OK, best to all, and TIA for any info sharing
