Re: Quiet Vac Pumps
I have been using the pump and reservoir kit that O'Zeeke refers to in his post above. rctous (aka Brian) has put together a nice, economical pump kit. It's been working well for over 9 months. I can't compare the noise level to the MES-DEA pump used by DIYguy. I suspect the MES-DEA is likely quieter and is also likely higher quality. It is also 2-3X the price.
The noise level is not objectionable, though I did add a pseudo muffler to it (foam placed over the exhaust port). I'd use this again. The photo shows the foam on the end of the reservoir. The pump is inside the reservoir.
