Ok i looked into purchasing a basic Stamets Laminar 12"x24" about $700
various commercial units $700 to OMFG $4,000 HEH thats sticker Shock .
then i googled up lots of DIY Laminar projects , wow lots solid builds and lots Really Crazy Ghetto sound and less then sound theory .
most seemed based on a 24" x 24" filter
i searched around and asked questions of sandman , Microbe and few others THANKS FOR ADVICE
SO i was shopping for a 24" x 24" x 5.85 filter i found a" good one but for only $20 more i could get a
24" x 30 " x 5.85 filter so i could set it long way for a 30 inch work area for grain ...agar ... ect or turn on side for 30 inch tall work area for tall bags .
so i ordered that filter .$190
the vendor also sells a 24" x 24" x 5.85 filter and a 24" x 48" x 5.85 filter
then i looked at LOTS .......LOTS ..........FANS .The snail type squirrel fans that pushed 1000 cfm or more were OUCH $300+ . SO I LOOKED INTO
INLINE FANS MOST WERE a propeller type fan blade CHEAP but really had bad drop in CFM with back pressure.
i found a inline style fan that was a squirrel wheel style fan that had low drop against back pressure rated at 1060 cfm $94
I also orders a router style fan speed controller $17
ok it only took 3.5 months to get filter ..turns out its a build to order item and was beck ordered THREE TIMES .
waiting on fan now .
the price onn the filter and fan i bought has gone up a cpl bucks since my purchase .
...................NOW MY FIRST QUESTIONS ......................
................FOR YOU INTERNET .......LAMINAR .........EXPERTS .......
.(1)....I am about to start designing cabinet .......i am thinking 3/4 cabinet finish plywood or maybe one of the newer kitchen cabinet laminates.
What advice on cabinet materials might you folks have to offer ..i know nothing about the newer laminates .?
(2)....I am curious as to air speed to be exciting face of filter to acheave a good protective laminar flow . i have a little device that i can measure that with .. my reading says about 100 pm err per min or so?
(3).......i was wondering how much work area out from front of filter face ...like how many inches from face of my filter should i have edge or working area table i will have 24 inch wide area but can scoot filter closer to table edge for optimal work area ...."
let me know if that makes since ?
(4)...also i see lots pics of people just working in front of laminar in open room ..............and lots were they have an open face enclosure going out surrounding face of filter..
What are prose and cons of these two configuration s?
ok please if you can provide some posative input please post your oopinions and Ideas .
oh and your questions
