FILTER SELECTION

Post by damunk »

Hi guys,

I am going to put a air filter because with the DIY boxes I made from wood and using filler I am abit concerned that there will be little bits breaking away initially. Is it okay to put a filter just before the motors.

Has anyone had issues with air flow restriction? Thinking about a simple flat one mounted to one of the boxes. Or perhaps a vacuum cleaner FOAM/spounge thin filter.

It will restrict flow, how much depends on the filter. I have used a really coarse open sponge that robbed 10-20 cfm @ 200

Paint the inside and outside of the flowbench, wood is porous and will leak. No worry about anything "breaking away" either.

Just one coat of wood paint?
Or undercoat required?

I paint my builds with "kilz" primer no specific reason though. Enough to seal the wood is all you need. I painted the outside of my personal build with Rustoleum, steel wool between coats and it has proven to be a very durable finish and it came out good enough for my shop.

Soooo I will put in my 2 cents, I did prime all wood before assembly then I glued and screwed the bench together, then i picture framed the entire internal of the bench with 3/4 x 3/4 yellow pine this was installed with adhesive caulk (phenoseal). 15ga brad nails and all included corners lightly caulked and fingered smooth. Once all this was dry I painted the entire internals of the bench with two coats of latex semigloss paint in bright white. I did this because 1.) i wanted to be able to see inside my bench and clearly view if there was dirt of foreign matter in the bench, later fount it easy to see shit you drop down the hole :-0 and 2.) Latex after time gets hard and if the bench moves or cracks in the corners etc it will make it easier to see.

A little extra paint goes a long way toward a professional looking build.

I also paint inside in white for the same reasons. White roll cages and cracks been around for years! I just slap it on and it goes everywhere. I use a 4" brush and only wipe one side. That way it doesn't get short anywhere. Total of 3 coats at least. I prime with nothing.

I will do that later. Just trying to get the manometer right at present. After that I will paint and find a decent filter.
3 coats of white.
