flowhood - please help me find right blower
    #12667325 - 06/01/10 03:41 PM (13 years, 8 months ago)

hello,
I'm posting for the first time here, but I've been reading Shroomery for quite a while now.
i must say that pretty much everything i know about mycology i owe to this community, for which i am grateful. awesome place, awesome people :smile:

lets get to the point.

few days ago i found pretty inexpensive HEPA filter so i decided it's time to build a flowhood. HEPA i found is 305x610x80mm 99.95 H13 filter (75 bucks including shipping), data sheet says it's 240Pa (so about 300 including prefilter) and 500 m3/h volumetric flow.

so, looking at this spec i need a blower that will deliver 500m3/h at 300Pa, right?

please take a look at this char:


if i understand correctly, the WK 200 blower is too weak, delivering about 350 m3/h at 300Pa and the WK 250 blower is too strong, delivering 600ish m3/h at 300 Pa?
what shall i do? should i get the WK250? isn't 600 m3/h too much for my HEPA+prefilter?

i will appreciate any help :smile:

if your blower is too weak, you wont get laminar air flow. too strong and you will be fighting to keep your stuff on the table.

when in doubt, go higher than you need and get a speed controller or a dimmer depending on what kind of blower you are getting.

if you can hold a lighter in front of it and its not extinguished yet it the flame stays at an angle, you are spot on

Pretty easy to find this info online. eBay has some really cheap inline fans, the brand Crystal Kings is ridiculously cheap. I picked up a 700+ CFM fan for $80 shipped.

My filter is 48" x 24" or 4 feet by 2 feet.

Agree it is a labor of love, you will be glad you built it with your own hands as well as now u will have a flow hood and u will have saved hundreds of dollars.
